Wiretapping Just The Start of VoIP's Security Woes

Security experts are once more urging businesses and consumers be wary of wiretapped Voice over IP (VoIP) calls -- as well as the vast number of potentially worse IP telephony vulnerabilities to which they may be exposed.

Last week, U.K. security researcher Peter Cox introduced a proof-of-concept that showed how easily Voice over IP phone calls could be intercepted. Cox, the former chief technology officer and co-founder of security vendor Borderware, successfully captured phone calls over a period of several months with a prototype Session Initiation Protocol (SIP) call monitoring tool.

The demonstration came as only the latest reminder that VoIP is vulnerable to monitoring. But experts warn that wiretapping is only the tip of the iceberg. (more)
