Slide 5 - Quiz-1 Rarely on line

True or false question.

I am rarely on-line. I spend most of my time just working in documents on my machine.  So I'm not much of a target for a hacker.

Actually, access to the internet, even if it's infrequent, may still leave you open to attack.

3.)    Set your updates to run automatically. 
4.)    Use strong passwords
5.)    Turn on the firewall in XP.

Slide 16 - Slide 16

Screen shot of the local disk C: drive map.

Personal information about yourself or others that should not be accessed unless for legitimate business reasons is considered "sensitive" data.  Protect your data and others' by keeping it secure.

Your home directory and other network drives are backed up on the server and are more secure.  Determine use of shared folders within your department.

True or false question.

My mother’s maiden name or the odd names of my pets are great passwords.  No one could ever guess those!

• Does not use personal information, such as, your phone number, street address, pet's name, etc.
• Includes both uppercase and lowercase letters, digits, punctuation, and/or spaces.

When picking passwords, avoid the following:
• The name of the operating system or the computer you’re using.
• Your phone number or your license plate number.
• Anybody’s birth date.
• A word in any dictionary.
