Role Variation by Authentication Method

Role assignment has many options under the umbrella of role derivation. While the system can simply use the role returned from the authentication server, it can also assign a role based on a number of attributes. When a user logs in using WPA2 they receive an open employee role, but when logging in with the same credentials using a captive portal, a reduced role is put into effect. Phones can share the same authentication as a camera but receive a different voice role after completing registration with a SIP server.

Wireless Intrusion Detection System

Due to the open nature of wireless networks they are prime targets for both unscrupulous individuals and casual hackers that happen to live in the area. To protect against unsanctioned wireless devices, use of Aruba’s Wireless Intrusion Detection System (WIDS) software module can automatically detect and defend against wireless attacks and “rogue” APs on the network.

Wireless Attacks

Acommon wireless network attack is called “man-in-the-middle.” During such an attack, a hacker masquerades as a legitimate AP using software on a laptop, and acting as a relay point, fools users and other APs into sending data through the laptop instead of the real AP. The attacker can then eavesdrop on conversations, modify or corrupt data, or run password-cracking routines.

Aruba Access Points monitor the air to detect other wireless stations masquerading as valid APs. When masquerading is detected, appropriate defense mechanisms are put into place. Aruba Mobility Controllers also track unique “signatures” for every wireless client in the network, and if a new station is introduced claiming to be a particular client, but lacks a proper signature, a station impersonation attack is declared.
