Is Your UC Secure?

In order to provide comprehensive security, all traffic going into and out of the network should be monitored. Security applications and appliances have to scan and monitor for malware, data leakage, and other threats. With Unified Communications, the threat landscape is a little bigger and a little different. It is as important as ever to monitor traffic and maintain security, but unified communications demand higher bandwidth and QoS (Quality of Service) requirements than standard data traffic, making it an even greater challenge to secure and protect a UC environment while maintaining voice quality. Join Jason Ostrom, Director of the Sipera VIPER Lab, and Eric Winsborrow, Chief Marketing Officer for Sipera Systems and moderator, Erik Lanask, Group Managing Editor at Technology Marketing Corporation, on Tuesday, July 22 at 11:00am ET/ 8:00am PT.

If you have ever set up or worked with a wireless network, you are probably familiar with the fact that the signal quality isn’t always the best. Depending on your wireless networking hardware and how you have it configured, the layout and materials used in the structure your network is in, and possible interference from other electronics and communications equipment, the wireless network connection can be erratic. The same can be said for those who may have worked with or set up a VoIP communications system. The issues are different, but the problems still arise with bandwidth and signal quality. It can be difficult to maintain the quality of voice communications over a VoIP network. Imagine then what types of issues you might encounter if you try to implement a VoIP communications system over a wireless network. Yikes! On May 1, Cisco is presenting a webcast entitled Extending VoIP to Wireless LAN’s which will cover six technical challenges you must address, capacity planning, roaming, security issues, and more.
