Course Description and Objectives
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, network protocols and Internet security.
This course provides a broad introduction to a variety of topics in applied computer, network, and system security. These include system/software vulnerabilities, applied cryptography, host-based and network-based security, privacy, anonymity, usability, security economics, risks and vulnerabilities, policy formation, controls and protection methods, and issues of law and privacy.

Note: No Single textbook covers all the topics listed here. Necessary handouts/weblinks will be given based on materials covered in the classroom.
Your semester grade will be based on a combination of homework assignments, quizzes, attendance, exam, and a term project. The approximate percentages are as follows:
- 5% - Attendance
- 15% - In-class Quizzes
- 25% - Homework Assignments
- 30% - Team Research Project
- 25% - Exams
Important Note: You will have one week to appeal for your grades after the graded assignments/tests are returned. So, please keep this in mind if you think that there is a problem/issue with the grading of your work.
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.
Cheating is defined as submitting work under your name that was not done entirely by you for individual assignments or by your team for team assignments. (This includes taking programs from the web or cutting text from web pages and pasting them into documents, even if the source is cited). Cheating will not be tolerated – those caught cheating will be reported to the Dean of Students. You should be aware of the Standards of Conduct posted at http://www.utep.edu/vpfa/student_affairs/student/studindex/htm.
