Securing your voice over IP

Phillip Pudney 2007

If you’re not already using Voice over IP (VoIP), you’re probably at least thinking about it. However with convergence comes new challenges. Unfortunately many organisations are deploying VoIP without considering the security threats, which can be extremely expensive and difficult to correct retrospectively.

This talk will present some of the common threats and vulnerabilities that affect VoIP and discuss some of the ways to mitigate them. If time permits, a live demo will show just how easy it is for an attacker to intercept your calls.
