Fending off VoIP security problems
04 December 2007
I'm hearing more about new kinds of attacks on LANs, such as voice-over-IP attacks or exploits that use printers as a source of attack. How can LAN security help me prevent those attacks?
It's absolutely true that these kinds of attacks are on the rise. In fact, the SANS Institute recently listed client-side attacks as one of today's most critical vulnerabilities. While it may be foolhardy for any of us to think we can fully prevent such attacks, you certainly have some strong options for mitigating the threat that they pose to your enterprise.
One of the first steps to take is to implement an authentication scheme in your LAN that encompasses devices as well as users. If you're pursuing something like 802.1x, it won't be sufficient because phones, printers, medical devices, robotics and other devices for the most part will not be able to support the required 802.1x supplicant.
