Man-in-the-Middle Protection

One of the common attacks possible in wireless networks is the "man-in-the-middle" attack. During a man-

in-the-middle attack, a hacker masquerades as a legitimate AP. Then, acting as a relay point, this man-in-the-

middle fools users and other APs into sending data through the unauthorized device. An attacker can then

modify or corrupt data or conduct password-cracking routines.

Aruba access points monitor the air to detect other wireless stations masquerading as valid APs. When such

masquerading is detected, appropriate defense mechanisms are put into place. Aruba mobility controllers

also track unique "signatures" for each wireless client in the network. If a new station is introduced

claiming to be a particular client, but without the proper signature, a station impersonation attack is

detected.

Policy Definition and Enforcement

Aruba WIP provides a number of policies that can be configured to take automatic action when a policy is

violated. Examples of wireless policies include weak WEP implementation detection, AP misconfiguration

protection, ad-hoc network detection and protection, unauthorized NIC type detection, wireless bridge

detection and more.

Using Wireless to Protect your Wired Network

Even if wireless LANs are not sanctioned at this time, no security conscious company can afford to do

nothing. Aruba's WIP will keep wireless traffic from working its way into the wired network through rogue

APs unknowingly attached to a network port. With Aruba's mobility system equipped with WIP, the

enterprise network is protected against wireless security holes. And when the enterprise is ready to deploy

wireless LANs, the Aruba system can be easily reconfigured to provide a scalable and secure wireless LAN

infrastructure.

Using Wireless to Protect your Existing Wireless Network

Aruba's mobility system with WIP delivers the detection and protection necessary to keep your existing

wireless network safe from undesirable wireless access. ArubaOS WIP complements and enhances any

existing WLAN deployment, including Cisco deployments, by providing advanced RF security and control

features not found in first-generation wireless products.
