It's unsettling, but it's a fact: The bedrock elements of unified communications (UC) services -- voice, video and instant messaging (IM) -- can be observed and modified by individuals that can gain unauthorized access to your core IP network. At minimum, unauthorized access opens the door to data leakage. In the wrong hands, however, an informed attacker could compromise network security via unified communications applications, access proprietary information, modify network settings and launch malware or eavesdropping attacks, jeopardizing an enterprise on many levels.
There are steps you can take to secure your UC services. The book Seven Deadliest Unified Communications Attacks provides useful insight to secure your UC applications.
In this chapter from Seven Deadliest Unified Communications Attacks, author Dan York illustrates how to safeguard voice, video and instant messages (IM) from unauthorized modification and eavesdropping attacks by explaining the goals, design and building blocks behind these intrusions. Find out why attacking unified communications services is so dangerous to enterprise security, how these attacks could potentially evolve and more.
