Computer and Network Security

Computer and Network Security is where the cryptography you've heard about stops being abstract math and becomes the actual machinery protecting real systems — you learn why TLS, PKI, VPNs, and signed email work the way they do, then move up the stack to how networks are actually defended in practice. Expect three homeworks, a midterm, and a written final, with weekly material split between the crypto foundations (Stallings) and Cisco Netacad modules covering firewalls, IPS, AAA, and ACLs. Coming after your networking and systems courses, this is the senior-year capstone that ties them together into a working security mindset — the baseline literacy expected of anyone touching production infrastructure after graduation.
