- What is UNIUYO-CYB 425 at the University of Uyo?
- UNIUYO-CYB 425 (VoIP and Multimedia Security) is a 2-unit, 400 Level course taught in the Second Semester at the University of Uyo, Akwa Ibom State, Nigeria. Securing voice-over-IP and multimedia traffic: VoIP network architecture and call-control protocols (H.323, SIP, MGCP), NAT/firewall traversal, and the encryption and best practices that mitigate VoIP-specific risks.
- What topics are covered in UNIUYO-CYB 425?
- The UNIUYO-CYB 425 outline covers 8 topics: Multimedia elements, characteristics, and storage formats; Techniques for streaming data traffic: VoIP and multimedia traffic; VoIP network architecture and protocols; SIP-based VoIP security issues; Call-control protocols: H.323, Session Initiation Protocol (SIP), MGCP — threats and security holes; How NAT and firewalls impact call setup, media streams, and latency; SIP NAT traversal: STUN, TURN, and ICE; VoIP risks, threats, vulnerabilities, and cryptographic protocols for VoIP security; VoIP management tools and best practices for risk mitigation.
- What textbooks are recommended for UNIUYO-CYB 425?
- Recommended reading for UNIUYO-CYB 425: VoIP and PBX Security and Forensics by Iosif I. Androulidakis; Hacking VoIP by Himanshu Dwivedi.
- How do I pass UNIUYO-CYB 425?
- Draw the SIP call-setup flow from memory — most exam questions probe understanding of the signalling sequence Understand why NAT breaks VoIP by default before learning STUN/TURN/ICE as the fix — the problem motivates the solution Connect VoIP encryption (SRTP, TLS for SIP) back to the cryptography course (CYB 311) Wireshark can capture and analyse real SIP/RTP traffic in a lab — practise identifying a call setup in a capture
