Establishing appropriate compliance and control metrics is critical when managing risk related to outsourced operations. Due diligence is required in order to properly assess whether the institution desires to be a business partner with a specific outside entity.
After entering into an outsourced partnership, contractual and financial metrics need to
be managed accordingly.

Risk assessment is a key component of information technology disaster recovery planning. In a large organization, it is often challenging to determine which applications are critical and who relies on which applications. The risk assessment process must include an analysis of what the cost is when the systems are down (both current and future costs).

Understanding Risks
Risk events must be considered in conjunction with controls that have been developed to ensure that objectives are met. In established areas where systems and processes exist, a residual risk approach works well. This approach begins by identifying controls already in place to achieve the business objective. Control gaps may then be identified. In this environment, the largest risk is that the existing controls are not being executed.
When considering new strategic initiatives or new business segments, the identification of inherent risks may better serve the organization. In this approach, risk events are listed along with a risk rating probability. Based on this analysis, the organization determines the appropriate design of controls.

Business Continuity Planning for a Pandemic
To address the business risks associated with a pandemic, processes and procedures should exist to ensure continuity of essential operations during an extended period of high illness rates in the workforce. Plans need to be made well in advance – by the time staff are becoming ill, it may be too late.
Critical business processes should be protected by training more personnel to take over essential roles. Simple changes in the work environment such as having fewer face-to-face meetings, rigorous hygiene, and frequent cleaning of common area surfaces may help to mitigate the risks.

Data at Risk
There are many reasons why data are at risk and why companies must do more to protect valuable data assets.
• Information is transmitted and archived in sophisticated systems with links to the
Internet.
• Companies are slow to deal with technology change.
• Data are stored on many types of electronic devices.
• Technology is continually changing.

Are Your Controls Efficient?
Last month, our focus was on management’s role in continuously monitoring the effectiveness of internal controls throughout the organization. To be effective, an internal control process must be one that assures the right things are being done.
Management is also accountable for assuring the efficiency of operations (IIA, 2007); for reviewing internal controls that assure people and systems are doing things right. Business objectives can only be met by doing the right things right. When effective internal control processes are not being performed efficiently, the overall business objective is still compromised.

Are Your Controls Effective?
Managers and supervisors are responsible for establishing appropriate controls and monitoring their effectiveness to provide reasonable assurance that the goals and objectives of their department are being met.
Do your controls:
-
Prevent or detect deviations early to limit costly errors?
-
Provide reasonable (not absolute) assurance of achieving objectives?
-
Operate effectively when compared to the costs of the potential error?
Or, are your controls:

Best Practices for Remote View/Control of Workstations
IT often uses remote tools to assist in legitimate troubleshooting of computer hardware or software issues. These features add risks for security and confidentiality when support personnel view your screen in real-time.
Use the following guidelines when authorizing remote view or control of your workstation:
-Do not accept remote view or control requests that you have not initiated. (If you did not place the call for assistance, then do not give access to anyone).
-If it is necessary to allow remote access, then only grant it to appropriate support personnel.
-Close all applications that are unnecessary to resolving the issue for which you need support.
-Remain at your workstation at all times when remote viewing or controlling is taking place.
-You are responsible for any actions taken while you are logged in, so watch carefully what action is taken on your computer.
-Always ensure that the remote view or control is disconnected/terminated after support personnel have assisted you.
-Be alert for “social engineering” attempts to gain remote access to your computer whether by phone or email. Report any attempts to your supervisor.
-If you are uncomfortable with actions taken during a remote control session, immediately end the session and tell your supervisor who will report the incident according to Purdue’s Incident Response Policy.

Computing Assets
Computing assets and associated risks relative to these assets must be identified in order to mitigate departmental or institutional risks. In a decentralized computing environment, each area must identify hardware, software, systems, services, facilities, or related technology assets. Risks related to these assets must then be identified which may include lack of system administration training, desktop access controls, operational policies, strong passwords, data protection, internal or external physical security, secured text transmissions, and natural disaster planning. Once assets and risks of each of these assets have been identified, appropriate solutions to mitigate the risks must be implemented.

Take Responsibility to Prevent Fraud
Everyone is responsible for ensuring that a culture of integrity is maintained at the University. We must never take any action that would be inappropriate or would violate laws or our policies. When confronted with new, unclear, or important situations, we need to apply the 5 point test to answer “Would it be right?”
- Would I have to hide what I did?
- Would it deceive anyone?
- Would it give me an advantage to which I am not entitled?
- Would I be happy to be on the receiving end?
- Would it be OK if everyone did this?

Electronic Mail
Electronic mail (e-mail), a primary communications mechanism, provides increasing risks for higher education. E-mail usage has grown tremendously and yet institutional expectations for managing e-mail usage have not kept pace.
Click here for Purdue University’s policy on e-mail.
Per this policy, e-mail stored on a University e-mail system will generally be preserved for no longer than 30 days after deletion. E-mail residing on the mail servers is retained indefinitely as are any e-mail items archived to files. Staff should not retain departmental information in this manner. Instead, e-mail containing information necessary to the University’s operation should be retained either electronically or on paper in departmental account folders.

Business Risks
Business risks exist in all areas including operations, revenue, expenses, regulations, control environments, and information technology. Some of the primary areas where internal controls may not be functioning as intended include physical controls, separation of duties, authorization, compliance, and data (integrity, reporting, and monitoring). In order to assess business risks and to determine if controls are effective, you need to understand the goals of the operation and compare the goals to the process.

A Quicker Way to Lock Your Computer
Whenever you step away from your personal computer, you should ensure that it is locked. On Windows-based machines, most people accomplish this by pressing the Ctrl, Alt, and Delete keys and then clicking the “Lock Computer” button (or pressing enter). An even quicker way is to press the “Windows” key and the “L” key simultaneously. (The “Windows” key is the key with the Windows icon on it.)

Best Practice for Network Security
Security is not something you have or don't have, it is something you do. Network security is a never-ending race between those who discover exploits and those who block them. That is why it is pointless to maintain an authoritative list of current vulnerabilities. The practical approach is to secure your server with all new vulnerabilities/patches today, then update your server each week (or day!) as the new vulnerabilities/patches arrive.

are Accountable for Effective Controls
Effective controls
allow organizations to manage operational and financial
integrity while complying with laws and regulations, which
increases confidence in business performance. Controls are
the essential outcome of policies, procedures, and guidelines
and are defined from policy statements. Each person is accountable
for ensuring effective controls. Ultimately, control or
compliance violations, whether malicious or accidental,
come down to people. The effectiveness of the control environment
is dependent on each person understanding that they are
accountable for certifications and reviewing and monitoring
information, and that approaching compliance is an ongoing
process.

Understanding
the "whys"
An internal control that is often
overlooked, and the importance often underestimated, is
understanding why certain tasks are performed in an operation.
Understanding why a task is performed is almost as important
to the internal controls as actually performing the task
itself. If an employee does not understand why they
are performing a step, errors may occur that are not detected.
For example, if an employee is assigned the task of matching
documents without understanding the ultimate purpose of
the step is to reconcile activity to general ledger, the
employee may not realize that the steps of matching documents
does not detect activity that incorrectly posted to general
ledger and does not detect activity that never posted at
all. Once the purpose of the task is understood, controls
are enhanced and the effectiveness of employee's work is
increased.

Monitoring
Ongoing
monitoring is a crucial management activity. There are two
approaches to ongoing monitoring: ongoing activities or
separate evaluations. Ongoing monitoring is part of the
normal, recurring operating activities. Because it is performed
on a real-time basis, it is more effective than separate
evaluations. Separate evaluations take place after the fact
and problems are not always identified quickly. Examples
of ongoing monitoring activities include regular management
and supervisory activities, variance analysis, comparisons,
reconciliations and other routine activities. Separate evaluations
vary in scope and frequency depending on risks and related
controls in managing the risks. Examples of separate evaluations
may include self-assessments, and the work that internal
auditors perform as part of their regular duties.

Passwords
You have likely heard considerable information about
identity theft but did you know that identity theft can
happen if someone compromises your password? If your password
is compromised, an unauthorized user has the same system
rights that you have. It is your responsibility to protect
system information by using a strong password.
Create
a strong password that you can remember. Never use consecutive
numbers or letters on your keyboard and never use a word
that can be found in a dictionary. Hackers use complex tools
that allow them to guess this type of password. A strong
password is at least eight characters, includes a combination
of letters, numbers, and symbols and is easy for you to
remember but difficult for others to guess. By using a strong
passphrase, you can establish a strong password that you
can remember.
Always
keep your passwords a secret and never provide your password
to anyone! Watch out for scams such as phishing. This is
a practice of sending bogus emails that appear to come from
trusted sources. You are asked to respond by entering your
login name and password (your password has just been compromised)!
Before responding to something that appears unusual to you,
check with your supervisor.

Monitoring
of Information Technology Event Logs
Well-conceived
and properly enforced internal controls include identifying
specific information technology (IT) events that should
be logged as audit entries. A logging process is required
in order to recreate pertinent system events and actions
taken by system users and administrators. A monitoring process
is required in order to identify questionable data access
activities, investigate breaches, respond to potential weaknesses,
and assess the security program.
Simply
logging the events is not sufficient; the logs must be reviewed
periodically. The following should be considered when reviewing
event logs.
- Follow-up on suspicious events such as intrusion
attempts, authorized accesses at unusual times, and
unusual changes to infrastructure devices.
- Identify, investigate, report, and respond to inappropriate
activity.
- Ensure that audit requirements and activities do
not unduly disrupt critical business processes.
- Agree to and control the scope of the events to check.
- Identify the individual performing event analyses
as one independent from those setting audit trail rules.
Ensure they are available and that they record who,
what, when, where, and why sensitive information is
released. Rules-of-evidence integrity must be maintained.
- Document all event capturing and analysis procedures,
requirements, and responsibilities, including when to
involve inforensics specialists.
- Develop a process to ensure that users comply with
access control procedures, including strong password
creation and protections.
- Audit all user activity where risk levels warrant.
- Employ event analysis support tools and/or e-intelligent
methods of correlating log data to detect suspicious
activity and reduce volume.

Technology Control Objectives*
What
are information technology control objectives? Information
technology control objectives are typically presented in
three major categories:
• Company Level
• General Controls
• Application Controls
At
the company level, controls set the tone for the entity
and include systems planning, enterprise policies, governance,
codes of conduct, and fraud prevention. At the general controls
level, controls are embedded in common services and include
systems maintenance, disaster recovery, physical and logical
security, data management, and incident response. At the
application level, controls are embedded in business process
applications and are designed to achieve completeness, accuracy,
validity and recording assertions and include authorizations,
approvals, tolerance levels, reconciliations, and input
edits.

Wireless
Vulnerabilities
The
ease of deploying wireless technologies in today's environment
comes as a mixed blessing. Installation and setup of a wireless
environment is a relatively easy task, however, securing
the wireless technology is another challenge altogether.
The user is the common ingredient in both wireless and wired
environments, and also the weakest link in both areas. Installing
and securing wireless technologies are two very different
processes. A user installing wireless devices must understand
the importance of security and know how to configure the
device to protect the organization's network and data. Sixty
to ninety percent of WLANs (Wireless Local Area Networks)
are deployed without the most basic of security mechanisms
(changing default names, enabling encryption, optimizing
placement of the Access Point, etc.). The challenge is not
plugging in devices and making them work. The real challenge
is understanding the security position that the organization
is being placed in by the configuration, knowing the difference
between secure and insecure, and knowing who to contact
(or knowing how) to change the configuration to protect
your organization.

The
Committee of Sponsoring Organizations of the Treadway Commission's
(COSO) Integrated Control-Integrated Framework
There
are five steps, or components, in the internal control framework,
all of which are management's responsibility. The five steps
are:
- The control environment contains informal,
and often intangible, soft controls such as ethics,
integrity, philosophy, and commitment to competence,
as well as formal controls like assignment of roles
and responsibilities.
- Risk assessment is management's identification
and analysis of risks to the achievement of its objectives.
- Control activities are the mechanisms management
establishes to ensure directives are carried out.
- Information and communication refers to employees
getting the information they need to do their jobs and
communication relates to the free flow of information
in the organization.
- Monitoring involves day-to-day oversight by
managers, periodic reviews by auditors, and the processes
management uses to address and correct known deficiencies.
Remember
that management is responsible for internal controls!

SARBANES-OXLEY
Even
though Sarbanes-Oxley is not directly applicable to colleges
and universities, it is important for colleges and universities
to assess policies and procedures with the conceptual framework
of Sarbanes-Oxley in mind. It is important to review internal
procedures and controls as well as monitor compliance with
requirements.

Controls
Internal
controls may be preventive, detective, or corrective. A
preventive control is designed to prevent undesirable outcomes
before they happen, a detective control is designed to identify
the undesirable outcome when it happens, and corrective
controls are designed to reverse the undesirable outcome
or ensure that it does not recur.
Detective
controls include reviews and comparisons as well as reconciliations.
These controls are critical to ensuring the accuracy of
the general ledger data. For example, subsidiary systems
must be reconciled with general ledger data to ensure the
accuracy of general ledger data.

Monitoring
Monitoring
is a critical internal control. Ongoing monitoring includes
regular management and supervisory activities. Examples
of ongoing monitoring include:
- Review of operating and financial reports to identify
inaccuracies or exceptions;
- Oversight of reconciliation processes and procedures
to ensure accuracy and proper separation of duties;
- Review of information indicating that problems may
exist;
- Oversight of control functions and identification
of deficiencies;
- Comparison of recorded data to physical assets; and
- Routine assessment of internal controls.

COSO
provides an excellent framework for evaluating your internal
control environment.
What
is COSO?
COSO
is a voluntary private sector organization dedicated to
improving the quality of financial reporting through business
ethics, effective internal controls, and corporate governance.
COSO was originally formed in 1985 to sponsor the National
Commission on Fraudulent Financial Reporting, an independent
private sector initiative which studied the causal factors
that can lead to fraudulent financial reporting and developed
recommendations for public companies and their independent
auditors, for the SEC and other regulators, and for educational
institutions.
Who
sponsored the National Commission?
The
National Commission was jointly sponsored by the five major
financial professional associations in the United States,
the American Accounting Association, the American Institute
of Certified Public Accountants, the Financial Executives
Institute, The Institute of Internal Auditors, and the National
Association of Accountants (now the Institute of Management
Accountants). The Commission was wholly independent of each
of the sponsoring organizations, and contained representatives
from industry, public accounting, investment firms, and
the New York Stock Exchange.
What
is the COSO integrated framework of internal control?
Integrated
Framework of Internal Control
- Control Environment
- Risk Assessment
- Control Activities
- Information and Communication
- Monitoring
What
are the Key Concepts?
- Internal control is a process. It is a means to an
end, not an end in itself.
- Internal control is effected by people. It's not merely
policy manuals and forms, but people at every level
of an organization.
- Internal control can be expected to provide only reasonable
assurance, not absolute assurance, to an entity's management
and board.
- Internal control is geared to the achievement of objectives
in one or more separate but overlapping categories.

Self Assessment
Controls
Self Assessment is a tool or strategy used to provide management
an opportunity to evaluate its own internal control environment
through process maps and internal control questionnaires.
Management can assess the overall performance of the operation,
compliance with policies and procedures, evaluate business
controls, and ensure effective business risk management.
If
you desire assistance

Internal
Control Who is Responsible for it?
The
short answer is EVERYONE in the Organization. While different
levels of the Organization may be responsible for different
aspects of internal controls, everyone has an obligation
to make sure adequate levels of internal
control exist. Five elements of internal control are
the control environment,
risk assessment, control activities, information and communication,
and monitoring.
Recent
legislation enacted by the United States Government (The
Sarbanes-Oxley Act of 2002), which generally applies to
all publicly traded companies, reinforces management's responsibility
for establishing and maintaining a system of internal controls.

Internal
Control What is it?
A
process within an organization designed to provide reasonable
assurance that:
- information is reliable, accurate, and timely
- compliance exists with policies, plans, procedures,
laws, regulations, and contracts
- assets (including people) are safeguarded
- resources are used economically and efficiently
- overall established objectives and goals are met.

Performance
Monitoring
Monitoring
is a process that allows for the assessment of the quality
of the department's performance over time. Key components
of monitoring include:
- Routine evaluations of the overall effectiveness
of the internal control systems, processes, and procedures;
- Assessment of the organization structure for effectiveness;
- Evaluation and review of policies and procedures;
and
- Evaluation of risk assessment procedures.
Ongoing
monitoring is critical to ensuring proper evaluations and
immediate changes, when necessary, to the department or
operation.

Preventive,
Detective, and Corrective Controls
Controls
give organizations the ability to achieve effective and
efficient operations, to produce reliable financial reports,
and to comply with applicable laws and regulations. Controls
are generally categorized into three major categories:
preventive, detective, and corrective.
Preventive
controls prevent undesirable outcomes before they occur.
They are more cost-effective than detective controls.
Examples of preventive controls include:
- Segregation of duties;
- Programmed edit checks;
- Use of access control software that allows only authorized
personnel to access sensitive files; and
- Employment of trustworthy, competent people.
Detective
controls detect that an error, omission, or malicious
act has occurred and report the occurrence. They measure
the effectiveness of the preventive controls. Some errors
cannot be prevented, so they must be detected when they
occur. Examples of detective controls include:
- Hash totals;
- Check points in production jobs;
- Past due account reports;
- Bank reconciliations;Cash counts; and
- Physical counts of inventories.
Corrective
controls take over when improper outcomes occur and
are detected. They are designed to identify the cause of
a problem and to correct errors arising out of a problem.
Examples of corrective controls include:
- Contingency planning;
- Back-up procedures; and
- Re-run procedures.

Information
Technology Controls
In
our August tip, we discussed the impact of SAS 94 on information
technology controls. Controls associated with computer operations
can be grouped into two broad categories general controls
and application controls.
General
controls commonly include controls over data center operations,
system software acquisition and maintenance, access restrictions,
security, and application system development and maintenance.
Application
controls include computerized steps within the application
software. They are related to manual procedures that control
the processing of various types of transactions. Together,
these controls serve to ensure completeness, accuracy, and
validity of all information in the system. This information
is identified, captured, processed, and reported formally
and informally. It is important to note that the quality
of information influences the quality of decisions.

Effective
Information Technology Controls are Critical to the University
In
April 2001, the American Institute of Public Accountants
(AICPA) issued a statement on auditing standards (SAS) No.
94 titled, The Effect of Information Technology on the Auditor's
Consideration of Internal Control in a Financial Statement
Audit. This standard provides guidance on the effect of
information technology on internal control and on the auditor's
understanding of internal control and assessment of control
risk. This standard notes that an organization's information
technology use may affect any of the five internal control
components, which are:
- The control environment
- Risk assessment
- Control activities
- Information and communication
- Monitoring
It
is the University's responsibility to comply with the standards
and the external auditors' responsibility to validate via
their opinion that we are materially compliant with the
standards. As you can see, effective information technology
controls are critical to the University. If you would like
more information, please contact our department.

NEVER
PROVIDE YOUR PASSWORD TO ANYONE
Only
you should know your password. If anyone requests your password,
even if they identify themselves as authorized to know this
information, advise them that you are not permitted to provide
your password and immediately advise your supervisor of
this request.
Passwords
are maintained by systems in a manner that makes them look
jumbled (it's called encryption). Once you type in your
password to any computer system, it should be encrypted
in such a way that no one can undo that encryption. That
is because no one needs to know what your password is besides
you.
Remember,
YOU ARE RESPONSIBLE FOR THE PROTECTION OF YOUR PASSWORD
NEVER PROVIDE IT TO ANYONE!

Assess
your Risks
One
approach to establishing a strong internal control environment
is to first review your operation and determine your business
risks. Business risks are identified in six major categories.
Within each business risk category, associated risks exist.
There are several questions that can assist you in evaluating
whether the business risks have been minimized. These include
but are not limited to:
- Revenues
Are we in compliance with revenue policies and procedures?
Do we have a current rate approval?
Are duties properly separated
Are reconciliations completed timely and effectively?
- Operations
Have new strategies or initiatives been evaluated for
changes in the control environment?
Are we operating efficiently and effectively?
Have we experienced personnel changes and are new personnel
familiar with policies and procedures?
- Information Technology
Have we evaluated controls associated with new technologies?
Do we have procedures to ensure continuity and disaster
recovery?
Is the technology infrastructure good?
Have we made any system changes that have not been evaluated
for proper controls?
Is the data secure?
- Regulatory
Are we in compliance with federal, state, and other
regulatory requirements?
- Control Environment
Do we properly safeguard assets?
Are duties properly separated?
Are internal controls functioning as intended?
Are we in compliance with policies and procedures?
Does oversight and monitoring exist?
- Expenses
Are resources properly used?
Are approval and reconciliation procedures appropriate?
Are duties properly separated?
Does oversight and monitoring exist?
Are we in compliance with expense policies and procedures?

Separation
of Duties
One
extremely important internal control is to ensure that duties
are properly separated. Duties must be divided among different
people to reduce the risk of error or inappropriate actions.
For example, responsibilities for authorizing transactions,
recording them, handling the related asset, and monitoring
the activity should be separated. Consider the following
when assessing your internal controls and if you recognize
that your operation is handling transactions in the manner
described, implement changes immediately.
Examples
of Inappropriate Separation of Duties
- An employee submits his/her timecard to the supervisor;
the supervisor approves (signs) the timecard and returns
it to the employee.
- A payroll clerk submits his/her timecard to the supervisor
for signature; the supervisor approves (signs) and returns
it to the payroll clerk for processing.
- A disbursement clerk authorizes expenditures, records
the expenditure, and monitors the ledger activity.
- One employee collects income (cash, checks, etc),
verifies the source of income to the supporting documentation,
prepares the required reports, and retains the reports.
- One employee writes checks, signs checks, and reconciles
the bank account.
- No independent monitoring or reviews of income or
expense occur within the operation.
- One individual makes program changes to the production
program and no independent review of the testing or
expected results is completed.
- Reconciliation and monitoring procedures rest with
the individual responsible for processing transactions.
- Checks are signed by the authorized signer and then
returned for mailing to the individual responsible for
preparing the bank reconciliation or maintaining the
ledger. Checks are presigned (signed in blank) and given
to the individual responsible for the bank reconciliation
or maintaining the ledger.
Please
contact us for more examples or if you are uncertain whether
duties are properly eparated within your operation.

Information
Technology (IT) Internal Controls
- What is internal control?
- Internal control is a process designed to provide
reasonable assurance regarding the achievement of objectives
including the reliability of data and reporting, effectiveness
and efficiency of operations, and compliance with applicable
laws and regulations
- Why are internal controls important to you and the
University?
- All staff have a fiduciary responsibility to ensure
data integrity
- Data integrity is critical for all computing systems
- Data must be protected in accordance with external
regulations and University policies and procedures
- A report generated with unreliable data can lead
to poor management decisions
- Good decisions and future directions are not possible
without good information (data)
- Good control and security implementation within and
around a system allows for protection of data (one of
the University's most important assets)

The
Fair Labor Standards Acts -- Know the Law!
The
Fair Labor Standards Act (FLSA) establishes minimum
wage, overtime, and record-keeping standards for employees
who are not exempt from its provisions. As a supervisor,
you must know the law and University policies and procedures.
Supervisors are responsible for proper monitoring of time
and for ensuring that time is properly reported by their
staff.
Know
the overtime policy and procedures as stated in the Business
Procedures Manual:
- The overtime policy and its regulations apply to
the employment of all regular and temporary staff members
(including student employees) who work in excess of
40 hours weekly or eight hours daily, except for those
who perform work classified as exempt under the Fair
Labor Standards Acts;
- Department heads or their designated representatives
authorize overtime when there are increased workloads,
emergencies, or work that requires employees with certain
skills, training, or experience. To prevent last minute
scheduling, supervisors should inform their employees
as soon as possible that they are needed for overtime
work.
- Overtime not requested but permitted or condoned
by a supervisor must be counted as "worked overtime";
and
- The University has certain classifications that are
monthly paid non- exempt staff. Monthly paid employees
who are eligible for the payment of overtime are to
be compensated at time and a half for overtime work.
Know
employee classifications and if your staff members are eligible
for overtime!
Further
questions or clarification can be obtained from Human Resource
Services-ask them.
The
University does NOT tolerate violations of The Fair
Labor Standards Act.

What
occurs during an audit?
Audit
Process
Although
every audit project is unique, the audit process is similar
for most engagements and usually consists of three stages:
Preliminary Review, Field Work, and Closure. Through these
stages, Internal Audit wants to determine ways to minimize
risks and increase efficiencies within your area taking
a University system-wide approach.
Preliminary
Review
After
the decision has been made to audit your area, we gather
information about your processes and procedures. We then
review and evaluate the existing internal control structure
and identify the audit objectives. Finally, we plan the
remaining audit steps necessary to achieve the objectives.
Fieldwork
The
fieldwork involves gathering data and identifying opportunities
for continuous process improvement. It is during this phase
that we determine whether the controls identified during
the preliminary review are operating in the manner you described.
Closure
A
written report is issued showing the results of the audit
steps performed. It will include advice and requests for
action as needed based on the results.

Risk
Element Identification
A
step to establishing a strong internal control environment
is to review processes and determine what risk elements
are contained within the process. Identifying risk elements
leads directly to determining control points that can be
implemented to help mitigate these risks. Risk elements
within processes can include:
Attitude
and competency of personnel involved in the process
- Work performed by newer employees tackling the learning
curve may need more thorough reviews Competent employees
help reduce risk, but they may be able to "outsmart"
the system
Accountability
placed on employees
- Expectations placed on employees and higher levels
of accountability should lead to lower risk
Age
of processes
- Newer processes are generally more risky; however,
older processes can also be risky if newer technologies
or information are not incorporated
Complexity
of processes
- Highly complex processes or systems are generally
more risky
Time
constraints
- Activities performed under pressure can be more risky
and have the potential formore errors

Logical
Access Controls
Legitimate
system users should be authenticated before they are allowed
to use the system, and they should be allowed access only
to the data they are authorized to use and then only to
perform specific, authorized functions such as reading,
copying, and adding to and detecting data. It is also important
to protect data from those outside the organization.
A
favorite electronic espionage tactic is to gain access to
a building and plug into an Ethernet jack in the wall and
talk to the system. By configuring they system to respond
only to hardware that it recognizes, this can be prevented.
To
restrict logical access, a system must differentiate between
authorized and unauthorized users utilizing what the user
knows or possesses, where the user is accessing the system,
or by some personal characteristic. Perhaps the most common
approach is by what a person knows. For example, the computer
could ask users a series of personal questions, such as
mother's maiden name. Or users could be asked to enter
a personal identification number.

Control
Activities for University Departments
Each
University department can utilize internal controls to assist
the organization in the achievement of the following objectives:
- Effectiveness and efficiency of operations.
- Reliability of financial reporting.
- Compliance with applicable laws and regulations.
Suggested
internal control activities are:
- Implement segregation of duties where duties
are divided among different people. No one person should
have control over all aspects of any financial transaction.
- Make sure a person delegated approval authority authorizes
transactions.
- Ensure records are routinely reviewed and reconciled
by someone other than the preparer.
- Make certain that equipment, inventories, cash and
other property are secured physically, counted periodically,
and compared with item descriptions shown on control
records.
- Provide employees with appropriate training to ensure
they have the knowledge necessary to carry out their
job duties. Make sure University and departmental level
policies and operating procedures are formalized and
communicated to employees. Documenting policies and
procedures and making them accessible to employees helps
provide continuity of activities in the event of prolonged
employee absences or turnover.

Physical
Access Controls
Both
the physical ability to use computer equipment (referred
to as physical access) and the ability to gain access to
company data (called logical access) should be restricted.
hysical access security can be achieved by the following
controls:
- Placing computer equipment in locked rooms and restricting
access to authorized personnel only.
- Having only one or two entrances to the computer room.
The entrances should be securely locked and watched
carefully by security guards and closed-circuit television
monitoring systems.
- Requiring proper employee identification, such as
a security badge, for passage through an access point.
Modern security badges incorporate photos and magnetic,
electric, or optical codes that can be read only by
special readers. With dvancedidentification techniques,
each employee's entry and exit may be automatically
recorded in a log that is maintained on the computer
and periodically reviewed by supervisory personnel.
- Requiring that visitors sign a log as they enter and
leave the site. They should be briefed on company security
policies, assigned visitor's badges, and escorted to
their destination.
- Using a security alarm system to detect unauthorized
access during off-hours.
- Restricting access to private secured telephone lines
or to authorized terminals or personal computers.
- Installing locks on personal computers and other computer
devices.

Self-Assessment
of Your Business Office Processes
Evaluating
your business office processes is an important step in ensuring
strong internal controls. When you evaluate your processes
you should look for:
- Procedures that were not implemented as intended;
- Proper separation of duties;
- Internal control points that do not exist anymore
(reasons could include staff turnover, changes in processes,
new technologies, etc.); and
- Unnecessary control points that if eliminated or
changed, would allow you to realize efficiencies.
More
common evaluation methods include:
- Flowcharting processes;Interviewing personnel involved
in processes;
- Walking through transactions start to finish; and
- Utilizing questionnaires.

Characteristics
of Today's E-Commerce World
As
opposed to yesterday's in-house computer application system,
an E-Commerce application is open to public exposure. It
is an extremely complex two-way network. Pushing information
out invites outsiders in, and web server systems can be
used as launching points for attacks.
Fundamentally,
Internet / Web security is a set of procedures, practices,
and technologies for protecting web servers, web users,
and their surrounding organizations. E-Commerce applications
must be protected from 6 major threats.
- Hacking;
intrusion with intent to harm
- Denial of service;
intent to prevent availability
- Viruses / worms;
intent to destroy or 'harass'
- Disclosure;
intent to share information not intended
to be shared
- Sabotage;
intent to damage or not to damage for
a fee
- Mimicking;
intent to copy with intent to embarrass
or defraud

Audit
Trail
An
audit trail is the evidence of actions performed upon data
from original documents to final disposition. It is a concrete
log of activities and events, either hardcopy or in the
form of a computer file, and exists as one document or file
or as a collection of documents. The existence of a reliable,
easy-to-follow audit trail is considered one indication
of good internal control in an organization.
Audit
trails are useful for maintaining security and integrity
of data and for recovering lost transactions. The purpose
of maintaining an audit trail is to ensure the possibility
of tracing errors to their source in order to investigate
their cause, and to trace the effects of any identified
errors on other reports and information items.
It
is essential that computer application systems include an
audit trail component. An electronic audit trail is a record
showing who has accessed a computer system and what operations
he or she has performed during a given period of time. An
effective electronic audit trail cannot be deleted or altered
in any way.
Basic
components of an electronic audit trail include:
- User name
- Date and time stamp
- Operation performed or attempted
- Subject(s) and object(s) of the operation
- Old value of data
- New value of data
- Status of the operation (completion result)

Internal
Controls
What
is internal control? Internal control is a process designed
to provide reasonable assurance regarding the achievement
of objectives including reliability of data andreporting,
effectiveness and efficiency of operations, and compliance
with applicable laws and regulations.
Why
are internal controls important to you and your organization?
- All staff have a fiduciary responsibility to ensure
data integrity. Data integrity is critical for all computing
systems and must be protected in accordance with external
regulations and internal policies and procedures. A
report generated with unreliable data can lead to poor
management decisions. Good decisions and future directions
are not possible without good information (data). Good
control and security implementation within and around
a system allows for protection of data (one of the organization's
most important assets).

Application
Security
There
are certain specifications that should always be considered
and clearly defined when designing or purchasing a system.
These include:
- Data Integrity - Performance measure based
on the rate of undetected errors/preservation of programs
or data for their intended purpose (i.e., audit trails,
access control);
- Authentication - The act of verifying the identity
of a user and the user's eligibility to access computerized
information. Designed to protect against fraudulent
logon activity (i.e., access control);
- Non-Repudiation - The user cannot later deny
performing a specific transaction (i.e., audit trails);
- Confidentiality - Protection against unauthorized
access to data (i.e., access control, authorization
procedures); and
- Availability - The system is available during
normal operational hours (i.e., server security).

Web
Server Security
Web
servers are vulnerable to attack and make attractive targets
since they may contain files with sensitive financial and
proprietary information and effectively bridge an organization's
internal and external networks.
A
properly secured web server offers only two TCP/IP services
to the outside world: HTTP on port 80 and HTTP with SSL
on port 443. Your web server is one of the most likely computers
to be compromised by an outside attacker. It is visible
and available so don't allow any sensitive financial and
proprietary information to reside on this server!

Effective
Written Communication
Effective
communication is an important component of good internal
controls. Statistics show that, based on visual design,
a person decides in 10 seconds if they want to read a document,
and 65% only read the summary of a business report. Clear,
concise communication will increase readability and help
eliminate misunderstandings.
Steps to Effective Written Communication
- Focus on the reader. Describe your audience, define
your purpose and message, and organize your thoughts;
- Write to express, not to impress. Draft your report
and summarize in one sentence what you want to say.
Be objective, avoiding negative language and eliminating
repetitions. Use "plain English," active voice,
and shorter paragraphs; and
- Proof your work. After taking a break, do a final
review of the document.

Change
A
known fact in today's business environment is "change."
Operational changes, business process changes, and system
changes are but a few of the changes we experience on a
daily basis. It is important to remember that the internal
control environment changes when other business processes
change. For that reason, the evaluation of the internal
control environment is an on-going process versus a static
process.

administration begins with management's commitment. Management
must understand and evaluate security risks. Written policies
clearly stating standards and procedures should be developed
and enforced. Security administration functions include:
- Maintaining access rules to files and resources;
- Maintaining security and confidentiality over the
issuance and proper maintenance of authorized user identifications
and passwords;
- Monitoring security violations and taking corrective
action to ensure that appropriate security is provided;
and
- Periodically reviewing, evaluating, and updating the
security policy.

LAN
Security
LANs
facilitate the storage and retrieval of programs and data
used by a group of people. LAN software and practices, if
properly implemented, provide security for these programs
and data; however, most LAN software default settings provide
only a low level of security. The LAN security provisions
available depend on the software product, product version,
and implementation. Commonly available network security
administration capabilities include:
- Declaring ownership of programs, files, and storage;
- Limiting access to read-only;
- Implementing record and file locking to prevent simultaneous
update; and
- Enforcing user ID/password login procedures.
Sensitive
data in a LAN environment should be password protected,
encrypted, or stored in an area with higher file security
than the common user access allows.

Financial
Statement Presentation and Management Assertions
Based
on Statements on Auditing Standards
Financial
statement presentation requires specific management assertions.
Assertions are management's representations that are contained
in financial statement components. They are classified according
to the following categories:
- Existence or Occurrence: Do the assets or liabilities
exist?
- Completeness: Are all transactions and accounts
that should be presented in the financial statement
included?
- Rights and Obligations: Does the entity have
the right to the asset and are the liabilities an obligation
of the entity?
- Valuation or Allocation: Have assets, liabilities,
equity, revenue, and expenses been included at appropriate
amounts? And
- Presentation and Disclosure: Are components
properly classified and disclosed?

Password
Security
While
user IDs control system access, passwords are the most common
form of user authentication. Basic control elements that
are critical to ensuring proper access and accountability
include:
- Adhering to University policy not to share your password
with someone else;
- Protecting your password from unintentional release;
- Memorizing your password (do not write it down);
- Making your password more difficult to guess by adding
numbers and special characters; and
- Creating a password that is unknown by others (do
not use the names of children, friends, pets, date of
birth, telephone number, dictionary words, etc.).
Remember,
careful use of your password protects both you and the University's
systems.

Understanding
the Control Environment
Statements
on Auditing Standards (SAS) Number 78, requires auditors
to obtain an understanding of internal controls. The control
environment sets the tone of an organization and includes
integrity and ethical values, commitment to competence,
board of directors or audit committee participation, management's
philosophy and operating style, organizational structure,
assignment of authority and responsibility, and human resource
policies and practices.
Since
electronic mail is gradually replacing conventional paper
mail, it is important to know the security risks involved.
E-mail messages are fairly easy to intercept and scan for
key words. This can be done routinely, automatically, and
undetectably on a large scale. Unless an e-mail message
is encrypted prior to being sent, it will travel through
potentially hundreds of servers and be accessible on all
of them.

Protecting
Sensitive Information
In
addition to protecting sensitive information on your workstations
and network, you should also protect sensitive information
that goes outside the control of your organization. Examples
of sensitive data include credit card information, student
information, and some personnel information.

The
Fair Labor Standards Acts -- Know the Law!
The
Fair Labor Standards Act (FLSA) establishes minimum
wage, overtime, and record-keeping standards for employees
who are not exempt from its provisions. As a supervisor,
you must know the law and University policies and procedures.
Supervisors are responsible for proper monitoring of time
and for ensuring that time is properly reported by their
staff.
Know
the overtime policy and procedures as stated in the Business
Procedures Manual:
- The overtime policy and its regulations apply to the
employment of all regular and temporary staff members
(including student employees) who work in excess of
40 hours weekly or eight hours daily, except for those
who perform work classified as exempt under the Fair
Labor Standards Acts;
- Department heads or their designated representatives
authorize overtime when there are increased workloads,
emergencies, or work that requires employees with certain
skills, training, or experience. To prevent last minute
scheduling, supervisors should inform their employees
as soon as possible that they are needed for overtime
work. Overtime not requested but permitted or condoned
by a supervisor must be counted as "worked overtime";
and
- The University has certain classifications that are
monthly paid non-exempt staff. Monthly paid employees
who are eligible for the payment of overtime are to
be compensated at time and a half for overtime work.
Know
employee classifications and if your staff members are eligible
for overtime!
Further
questions or clarification can be obtained from Personnel
Services-ask them.
The
University does NOT tolerate violations of the Fair
Labor Standards Act.

Understanding
Domain Names and Trademarks
With
the growing number of new web sites comes potential conflict
with established web sites regarding domain names and trademarks.
Infringements or unauthorized use of a domain name or trademark
can result in legal recourse. It is important to understand
the definitions and their differences.
Domain
Name:
- A unique name that identifies an internet site;
- A name by which a company or organization is known
on the internet;
- Often established on a first-come, first-served basis;
- Registration of a domain name does not have trademark
status;
- Wise to obtain a trademark registration immediately
upon registering a domain name; and
- Responsibility of the company to determine that their
domain name is not infringing upon the rights of a third
party.
Trademark:
- Any word, name, symbol, device, or any combination
thereof that identifies the source of goods or services,
whether or not they are registered;
- Conduct searches before use and registration of a
trademark as a domain name to ensure that an infringement
has not occurred;
- Registration does not mean ownership; and
- Trademark metatags are an infringement.

Digital
Signatures
As
use of the Internet for business purposes increases, so
does the need for establishing proper identification and
authentication of the parties involved. The use of digital
signatures may provide the assurances we need.
What
is a digital signature?
A
digital signature is an electronic signature formed using
two related keysa public key and a secret or private keyand
is frequently regarded as the electronic equivalent of handwritten
signatures. The objectives of digital signatures are to
allow the recipient to prove the identity of the sender
and assure the integrity of the data being transferred.
What
are some legal considerations?
- Proving the integrity and origin of the data and ensuring
that they can be verified by a third party (non-repudiation);
- Establishing an infrastructure that supports legal
considerations;
- Recognizing that legal jurisdictions may not acknowledge
the technique of another, e.g., Indiana may differ from
Illinois; and
- Verifying reliability of the certification authority
(the third party).

Enforcing
Controls
If
employees are to accept controls willingly, they should
understand what the controls are seeking to do and their
responsibility in relation to the controls. When discussing
responsibility, it is important to communicate the objective
as well as the action required to obtain the objective.
When lack of communication occurs, the following problems
can develop:
- Controls are perceived as unreasonable, creating apathy
among the employees;
- Controls are considered useless and, therefore, ignored;
and/or
- Sloppy application of controls occurs.
Educate
personnel and then ask employees for feedback. When training
and feedback are embraced by the organization, a team environment
is created and employees are vested in the success of the
control environment.

Factors
That Can Adversely Affect Control
Two
essential components of control are execution of control
procedures at the operating level and clear direction from
top management. Despite knowledge of control procedures,
employees at any level can effectively destroy a potentially
adequate control system. Factors that can adversely affect
control and segregation of duties include:
- Controls in place but not effectively used;
- Inefficient controls established;
- System in place but not being used;
- Access to assets not strictly controlled; and/or
- Lack of controls.
A
periodic review of company controls is crucial, giving consideration
to the above factors. Engage in discussion with personnel
at the operating level as well as top management to receive
feedback on your current policies.

Separation
of Duties
Duties
are incompatible if one person can perpetuate and conceal
errors and irregularities while performing day-to-day activities.
If the same person is the originator and reviewer of a document
or transaction, no real protection against errors exists.
Consider the following controls in authorization, custody,
and accounting to ensure segregation of duties:
- Assign specific responsibilities within the revenue,
income-producing, or review cycle to different individuals;
- Involve an independent third party as a check;
- Cross-train individuals who perform no incompatible
duties to cover for vacation periods; and
- Conduct periodic checks for circumvention of existing
controls.
Even
with an efficient checks and balance system in place, adequate
control systems can be destroyed. Next month we will discuss
factors that can adversely affect control and segregation
of duties.

Internal
Controls and Separation of Duties
Implementation
of effective internal controls is the responsibility of
the department and is shared throughout the University.
Controls are designed to protect the University against
losses caused by outsiders or caused by internal embezzlement,
inefficiencies, ornegligence and carelessness. Controls
are designed to protect innocent people. Controls typically
fall into the following five categories:
- Adequate separation of duties
- Proper procedures for authorization
- Adequate documents and records
- Physical control over assets and records
- Independent checks on performance (quality assurance
reviews)
The
review of an internal control environment is on going in
nature. As processes and eople change, the control environment
also changes. Be aware when changes have ccurred and reevaluate
the internal control environment. The Internal Audit Office
would be happy to assist you in this review process.

Network
Dial-in Security
It
is possible to break network security using dial-in modems.
Without dial-in controls, a caller can dial in and try passwords
until they gain access. Once in, they can hide destructive
pieces of software, pass to other networks, and steal data.
To minimize the risk of unauthorized dial-in access:
- Remote users should never store their passwords in
plain text login scripts;
- Portable PCs should be protected by physical keys
and/or BIOS based passwords in case dial-in scripts
or sensitive data may be stolen;
- Dial-back modems should be used to call back only
authorized remote users; and
- One-time password generator devices should create
a unique password for eachlogin to the system.

Environmental
Controls
As
with physical security vulnerabilities, environmental vulnerabilities
to data centers could result in serious losses to an organization.
Environmental controls reduce the risk of disruption of
business activity. Items to control and monitor include
air quality, electrical power, and ground and atmospheric
conditions. Examples of common environmental controls include:
- Water detectors - in the computer room, should be
placed under raised floors and near drain holes even
if the computer room is on high ground.Hand-held fire
extinguishers - should be strategic locations throughout
the facility and inspected annually.
- Smoke detectors - should be above and below the ceiling
tiles throughout the facility. Detectors should produce
an audible alarm as well as be linked to a monitored
station.
- Fire suppression systems - designed to automatically
activate immediately afte detection of high heat typically
generated by fire. Like smoke detectors, the system
should produce an audible alarm and be linked to a central
station that is regularly monitored.
- Uninterruptible Power Supply (UPS) system - continues
to provide electrical powerto the computer from a certain
length of time in the event of a power failure. Most
UPS systems also "cleanse" the power to ensure
wattage to the computer remains consistent.
- Prohibit eating, drinking, and smoking within the
Information Processing Facility.

Physical
Data Center Controls
Physical
security vulnerabilities to data centers could result in
financial loss, legal repercussions, loss of credibility,
or loss of competitive edge. Physical access controls are
designed to protect the organization from unauthorized access.
These controls should limit access to only those individuals
authorized by management. Examples of some of the more common
access controls are:
- Bolting door locks -- These locks require the traditional
metal key to gain entry. The key should be stamped "do
not duplicate."
- Combination door locks (cipher locks) -- This system
uses a numeric keypad or dial to gain entry. The combination
should be changed on a regular basis or whenever an
employee with access is transferred, fired, or subject
to disciplinary actions. This reduces the risk of the
combination being known by unauthorized people.
- Electronic door locks -- This system uses a magnetic
or embedded chip based plastic card key or token entered
into a sensor reader to gain access. A special code
internally stored in the card or token is read by the
sensor device that then activates the door locking mechanism.
- Biometric door locks -- An individual's unique body
features, such as voice, retina, fingerprint, or signature,
activate these locks. This system is used in instances
when extremely sensitive facilities must be protected,
such as in the military.
Other
methods include photo IDs, video cameras, security guards,
escorted/controlled visitor access, dead man doors (two
doors that only allow entry by one person at a time), terminal
locks, and alarm systems.

Workstation
Security (Part II)
As
presented in the November 1998 tip, workstation security
can pose a large risk to data security. Any time a user
leaves a workstation while it is logged into an application
or just a network, it offers an opportunity for someone
else to use that workstation and account to alter or view
Purdue University data. Supervisory staff should take a
role of "security officer" in their areas by the
following:
- Make sure all users are aware of their security responsibilities;
- Randomly check workstations when no user is present
to ensure that the workstation was either automatically
locked (via a screen saver with password) or manually
locked by the user; and
- If the workstation is not locked, then any open applications
should be noted to evaluate the risk of someone tampering
with the data and the user should be reminded of their
security duties.

Year2K
The
year 2000 is a problem affecting all University academic,
research and administrative units. Efforts should be made
to identify systems and processes that fall under the classification
of "high priority". High priority systems and
processes are those which if they failed could cause:
- A shut down of University operation, or hamper significant
portions of research or instructional activities;
- Health hazards to individuals;
- Loss of revenue (students, state, government investments,
contracts, grants, services, etc.) orSignificant litigation
expenses or losses.
If
you have issues or concerns that you feel need further review
or discussion, please contact the Internal Audit Office.

Procurement
Card Purchase Controls
(Reference
the Purdue University Departmental Purchasing Card Handbook)
Assess
the control environment by asking the following questions
regarding segregation of duties:
- Is the person making purchases different than the
person who is approving the purchases?
- Has the person approving the purchases been granted
comptroller authority?
- Is the person performing the reconciliation different
than the person who is purchasing and approving the
purchases?
- Is the review and approval of the reconciliation,
supporting documentation, and ntramural approval performed
independently of the procurement function?

- Have we developed written contingency or backup plans
in the event that "fixes" do not work as planned
or we do not identify the date sensitive embedded systems?

Internal
Controls
Some
employers estimate that as much s $40 billion is misappropriated
annually by employees from their employers.1
Unfortunately, nonprofit organizations are not immune toemployee
defalcation.
Developing
strong internal control procedures is essential to deterring
internal theft. One of the most important controls is ensuring
that no single individual has absolute control without proper
or adequate oversight. Circumstances or events that may
cause the rganization or operation to be vulnerable include:
- Lack of control consciousness;
- Opportunity; and
- Motivation.
Good
internal controls are essential over cash, accounts receivable,
inventory, purchasing functions, and payroll and personal
expenses. Remember, the important elements of internal controls
include information, communication, and monitoring of the
internal control systems.

Benefits
of Control:
- Internal controls are a positive means of helping managers
and their staffs achieve objectives and goals. Good controls
protect the organization and the employee. One basic control
is comparing actual outcome with those planned.
- Operating standards are also key to the control environment.
They establish the kind of performance expected and are
quantitative results. Ongoing review of the ontrol amount
is necessary to ensure that controls do not become obsolete
as changes are made in the operation and to operating
standards.

Workstation
Security:
Workstation security
can pose a large threat to data security. Even if all possible
precautions are taken in choosing and protecting a password,
an account can still be ulnerable if the user remains logged
in while away from their computer. Someone could use that
computer to change University data, and the transactions
would list the account owner as the responsible party. They
could also use that computer to look up sensitive information
that would normally be unavailable to them. To avoid this
problem:
- Log out of all accounts while away from the computer;
- Use the screen saver password option and set the screen
saver delay to just a few minutes. Use the same principles
for selecting a screen saver password that are used to
select all other passwords.

Password
Security:
While
the user ID controls system access, passwords are the most
common form of user authentication used in information technology.
There are basic control elements that are critical to ensuring
proper access and accountability.
- It is against University policy to share your password
with someone else;Protect your password from unintentional
release;
- Never write your password down, and never display
it where it is accessible to others;
- Never use a password that is information known by
others, i.e., the names of children, friends, pets,
date of birth, telephone number, dictionary words, etc.
Remember,
careful use of your password protects both you and the University's
systems.
