CSCD 434 — Network Security

Principles of securing networked computer systems. Topics include network threats and vulnerabilities, cryptographic protocols, authentication, firewalls, intrusion detection, VPNs, wireless security, and secure network design.

ABET student outcomes

Student outcomes defined by the ABET Computing Accreditation Commission. Outcome 7 applies to cybersecurity-designated programs.

• ABET 1 strong Analyze a complex computing problem and apply principles of computing and other relevant disciplines to identify solutions.
• ABET 7 primary Apply security principles and practices to maintain operations in the presence of risks and threats. (Cybersecurity / Cyber Operations only.)
