VoIP security auditing is becoming more and more complex ... Not!
I am curious how people can conduct penetration tests of a complex VoIP system when they barely understand how VoIP infrastructure works. Today, security people are still stuck to auditing practices from 1990s. When asked to do a penetration test, a consultant often is only looking at past issues that can be detected using various vulnerability scanners. Very few of them know that vulnerability scanners have extremely bad coverage of vulnerabilities in VoIP solutions. And even if the tools did know VoIP, who really cares about past issues that might have been relevant several years ago.
How to troubleshoot sluggish apps
There's more at stake than lost productivity when application response times slow to a standstill. Company revenue also takes a hit. Here we analyze three scenarios in which application-performance problems could elude network managers.
What are critical issues with VoIP service?
VoIP services are rapidly becoming the bread and butter of enterprise voice networks, as roughly 72% of all enterprise voice lines shipped by vendors in 2007 were IP-capable. Now that companies are definitively moving away from the traditional Time-Division Multiplexing (TDM) voice networks and into Session Initiation Protocol-based (SIP) VoIP networks, we examine the VoIP industry's most pressing issues, including SIP interoperability, TDM-to-SIP transition services and VoIP security issues.
