CS 4351 - Computer Security

Spring 2014 Course Syllabus

Course Description:
General concepts and applied methods of computer security, especially as they relate to confidentiality,
integrity, and availability of information assets.
Topics include system security analysis, access control and various security models,
identification and authentication, protection against external and internal threats,
communication protocols and internet security.

Course Goals:
With the multiplication of tasks that are performed on computers and the advent of globalisation of computing in general,
the topic of computer security becomes more and more important.
We see in this course what is computer security,
especially as it relates to the protection of information stored on the computers and exchanged between computers.
Topics include: system security analysis, access control and various security models, identification and authentication,
security in UNIX and Windows, communication security, cryptography, internet security, e-commerce security protocols.

Exams and Grades:
There will be a midterm, a final, and a research report.
The rest of the grade will be based on written and/or programming assignments.
The following percentages will be used in formulating the final grade:

  • Midterm 25%

  • Final 30%

  • Research Report 10%

  • Assignments 35%

Standards of Conduct:
Students are expected to conduct themselves in a professional and courteous manner,
as prescribed by the Standards of Conduct.
Students may discuss work assignments and programming exercises in a general way with other students,
but the solutions must be done independently.
Similarly, groups may discuss group project assignments with other groups,
but the solutions must be done by the group itself.
Graded work should be unmistakably your own.
You may not transcribe or copy a solution taken from another person, book, or other source, e.g., a web page.
Professors are required to -- and will -- report academic dishonesty and any other
violation of the Standards of Conduct to the Dean of Students.

If you have a disability and need classroom accommodations,
please contact The Center for Accommodations and Support Services (CASS) at 747-5148,
or by email to, or visit their office located in UTEP Union East, Room 106.
