Recommended textbooks

  • VoIP and PBX Security and Forensics — Iosif I. Androulidakis

    2nd ed. — focused specifically on VoIP security threats

  • Hacking VoIP — Himanshu Dwivedi

    Practical, attack-focused treatment of VoIP protocol security

How to 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
