NAI's Sniffer Wireless is an application and security management product for companies with wireless devices. The product allows network administrators to monitor the configuration of wireless devices on their network to support vulnerabilities, monitor the radio frequencies used by wireless devices to troubleshoot conflicts and detect rogue wireless devices that have attached to a wireless LAN.
The 802.11a standard is a cousin to 802.11b used by many wireless products designed for the homes and small offices.
802.11a is geared to businesses interested in wireless technology, but with bandwidth-hungry applications such as those displaying multimedia presentations. It provides much higher bandwidth connections to wireless clients, up to 54Mbits per second in the 5GHz band as opposed to 11Mbits per second in the 2.4GHz band for 802.11b.
However, higher bandwidth equates to a shorter range. 802.11a supports the 54Mbits per second for clients at about 60 feet from an access point, whereas 802.11b can support 11Mbits per second at up to 300 feet from a wireless access point.
In expanding Sniffer to support 802.11a networks, NAI is competing with a host of other companies to grab a piece of the wireless security market.
Companies such as AirDefense, Internet Security Systems and Netstumbler.com all offer competing security products for sniffing out vulnerabilities in wireless networks and securing wireless access points that can be used by attackers to gain direct access to corporate networks behind the firewall.
Sniffer Wireless with support of 802.11a is available immediately.
