Course Overview
- This specialized course delves into critical VoIP security, addressing the unique vulnerabilities of modern communication systems. As businesses increasingly rely on converged networks, securing VoIP infrastructure against cyber threats (eavesdropping, fraudulent calls, denial-of-service) is paramount for privacy, operational continuity, and financial stability.
- Designed for IT professionals, network administrators, and cybersecurity enthusiasts, it offers actionable strategies and essential tools applicable to real-world scenarios. Participants will gain a holistic understanding of inherent VoIP risks and learn to implement robust defense mechanisms.
- Meticulously updated (December 2024), the curriculum provides relevant, up-to-the-minute knowledge. This guide helps fortify vital communication channels against persistent threats, whether for small offices or large enterprise unified communications platforms.
Requirements / Prerequisites
- Foundational understanding of basic networking concepts (TCP/IP, routing, switching).
- Familiarity with VoIP system architecture and functionality (SIP, RTP).
- Basic awareness of common cybersecurity principles (malware, DoS attacks).
- No advanced programming skills; command-line comfort is beneficial for tool demonstrations.
- Access to a computer with an internet connection; virtual machine software recommended for hands-on practice.
Skills Covered / Tools Used
- Skills Covered:
  - Conducting comprehensive risk assessments for VoIP infrastructure, identifying vulnerabilities.
  - Implementing secure configuration hardening for VoIP components (IP phones, softphones, PBXs).
  - Deploying and managing Secure Real-time Transport Protocol (SRTP) for encrypted voice traffic and Transport Layer Security (TLS) for SIP signaling.
  - Performing basic vulnerability scanning and reconnaissance against VoIP networks to discover exposed services.
  - Developing and enforcing robust security policies for VoIP system usage.
  - Understanding incident response fundamentals for VoIP security breaches.
  - Analyzing VoIP packet captures using specialized tools to diagnose security issues.
- Tools Used (Examples):
  - Packet Sniffers: Wireshark for in-depth analysis of SIP and RTP traffic, identifying anomalies.
  - VoIP Platforms: Open-source PBX solutions (Asterisk, FreePBX) for secure configuration demonstrations.
  - Vulnerability Scanners: Nmap with specific SIP-related scripts for endpoint discovery and attack vector identification.
  - Security Testing Tools: Introduction to specialized VoIP security assessment tools like sipvicious, svmap, or relevant Metasploit modules.
  - Softphones & Clients: Utilizing secure softphone clients (e.g., Linphone, Jami) to demonstrate secure connection setups and encryption verification.
