CS 556 - Computer Security

Information is an important strategic and operational corporate asset. Computers and computer networks, which are increasingly being used for storing and retrieving information, consequently need to have adequate security measures that can safeguard sensitive information.

This course will introduce the students to the rapidly emerging area of computer security. The topics that will be covered in this course are basic security concepts, access control models, multilevel security, viruses, Trojan horses and worms, trusted computer systems evaluation, cryptography, authentication and identification and security protocols.

The students taking this course will have knowledge of the fundamental principles of computer security. They will be in a position to understand the many different threats that endanger information processing systems and will be able to formulate policies and implement defenses against these threats. The knowledge acquired will allow them to be successful in computer security related careers. It will also allow them to pursue more advanced studies in information systems security.
