Interdisciplinary Program in Information Security

We are pleased with your interest in our graduate program. Before you continue with the electronic application for admission, we wish to ensure that you are familiar with the minimum requirements for admission to graduate degree study in the Interdisciplinary Program in Information Security. It is important to recognize that although satisfaction of these basic requirements does not guarantee graduate admission, failure to satisfy these requirements may lead to automatic denial of admission.

Supporting Documents: Additional documents are required to support the application. Supporting documents should be mailed directly to the graduate program to which you are applying. Supporting documents include the following, unless specific instructions are noted in the "Completing the Application" section of this page:

  • Transcripts - Interdisciplinary Information Security will accept unofficial transcripts and/or academic documents uploaded through the online application system for review purposes.  You will only need to provide official transcripts and/or academic records at the request of Interdisciplinary Information Security or if you are recommended for admission.
  • GRE Test
  • English Proficiency
  • Recommendation letters
  • Statement of Purpose - MUST include text addressing why you are applying to the interdisciplinary program instead of one of the departmental programs, e.g., CS or CNIT.
  • Writing sample -The writing sample should be a paper, project or research report on which you are the only author, one you submitted for a course as an undergraduate or graduate student and on which you received a good grade. It should be 10 pages or less and demonstrate your ability to write and reference as a graduate student. We do not need to see the remarks of the instructor or grade, only an electronic copy of your work. Most students keep their e-files for works they have submitted, so it should just be a matter of choosing something from previous assignments. If it has been many years since you were at university, then submit a piece of written work you have recently done on your job, perhaps a proposal or project description.
