  • Identify the security risks of VoWLAN systems.

  • Differentiate the various encryption and authentication solutions.

  • Understand tips for implementing VoWLAN systems.

Because VoWLAN systems make use of wireless technology, you must consider security issues and corresponding countermeasures. This chapter addresses security issues and provides an overview of the security mechanisms available for protecting VoWLAN systems.

Security Implications

To fully appreciate the need for security for VoWLAN systems, you need to understand the risks of not implementing security beyond the default wireless LAN configuration. The primary implications are unauthorized access, passive monitoring, and denial of service, as shown in Figure 5-1. When deploying a VoWLAN system, assess the potential harm that can be done based on these implications, and determine which security solutions will provide the most effective countermeasures.
