ECE 5560 Network and Computer Security (3C)

Introduces both fundamental security principles as well as real-world applications of network and computer security. Covers a wide range of topics including authorization and access control, basic cryptography, authentication systems, e-commerce security, sensor network security, and legal and ethical issues.

What is the reason for this course?

Past experiences have shown us that security mechanisms of a given system or network must be properly designed from the very beginning, and not added on as an afterthought. If the required security mechanisms are not carefully integrated into the target system/network a priori to deployment, potential security breaches can inflict enormous damage. This issue is becoming more critical than ever as we see an increase in the exchange of sensitive information (e.g., medical records, financial data, etc.) over insecure network links. The design, deployment, and management of secure systems or networks require the ability to understand core security concepts, analyze the security vulnerabilities of a target system, and design necessary cryptosystems for the target system. This course provides requisite knowledge of fundamental security concepts and their applications that are needed by students who are conducting research in security-related topics.

Typically offered: Fall. Program Area: Computers.

Prerequisites: 4564 or 5565.

Why are these prerequisites or corequisites required?

The prerequisite is ECE 4564 or CS 4254 or ECE/CS 5565. Graduate standing is required. Students should have knowledge of the principles and concepts of computer systems and networks. Students should also have basic background knowledge in random variables and stochastic processes. The three courses cited above should provide students with sufficient prerequisite knowledge.
