Spotlight Story
How intrusion prevention costs compare

Joanie Wexler By Joanie Wexler
With all the security talk in the air at last week's RSA Conference in San Francisco, it seemed fitting to return to our ongoing discussion of wireless intrusion detection/prevention systems. As you likely know, WIPSs work to keep unauthorized devices from connecting to your wired and wireless networks and to prevent your internal authorized wireless client devices from associating with unauthorized access points.

Intrusion prevention strategies for 11n There are several ways to scan your 802.11n air environment for nasty goings-on. At a glance, the options seem pretty straightforward. However, you need to look carefully under the hood to draw a true apples-to-apples comparison of the accuracy and cost of the various offerings.

Cisco helps avoid security scrimping in cash-tight times Many Wi-Fi vendors have integrated dedicated wireless intrusion prevention systems (WIPS) directly into their 802.11n systems. Cisco, for example, recently released an application called Adaptive Wireless IPS integrated with a multifaceted attack correlation system in its Wireless Control System (WCS) network management and security policy platform.

802.11n support added to wireless intrusion defense Existing wireless-LAN intrusion-prevention systems have a blind spot: Until they're upgraded, they can't detect radio signals from 802.11n WLAN gear.

Companies pair PoE with wireless IPS PowerDsine partnered with AirTight Networks this week to bring together PowerDsine's equipment for supporting Power over Ethernet and AirTight's wireless intrusion-prevention systems.

Space invaders: You and WIPS This situation points to the need for a wireless IPS even if you haven't implemented wireless LANs internally, because all of your new notebooks have built-in wireless.
