Many government agencies and commercial entities that transmit highly sensitive information over wireless networks mandate that strong Layer 2 encryption technologies be deployed to ensure absolute data privacy. U.S. DoD Directive 8100.2 requires that all data transmitted using commercial wireless devices be encrypted at Layer 2 or Layer 3. The U.S. Navy and Army are requiring Layer 2 encryption, and cryptographic engines used for all sensitive government communications must be validated as meeting FIPS 140-2 requirements. xSec has been designed to address this requirement and to provide a number of additional benefits. Wireless Intrusion Detection Aruba's Wireless Intrusion Protection (WIP) module eliminates the need for a separate system of RF sensors and security appliances. The WIP module provides extraordinary capabilities to Aruba's enterprise mobility system, giving administrators visibility into the network, along with the power to thwart malicious wireless attacks, impersonations and unauthorized intrusions. Wireless intrusion detection is only the first step in securing the corporate environment from unwanted wireless access. Without adequate measures to quickly shut down intrusions, detection is almost worthless. Without accurate classification of APs and stations (e.g., valid, rogue, or neighbor), providing an automated response to possible intrusion is impossible. Aruba access points constantly scan all channels of the RF spectrum, capturing all 802.11 traffic and locally examining the captured data. Only policy violations are sent to the central mobility controller to ensure minimal impact on wired network performance. While scanning the environment, the Aruba system learns about all wireless APs and stations and classifies these devices based on traffic flows seen on the wire and in the air. This traffic is collected and correlated on the mobility controller. Aruba's WIP module provides both detection and prevention capabilities. Users and devices are detected and classified so administrators can react to both unintentional and malicious WLAN access. No other system on the market provides such capabilities. Unique Station and User Classification Aruba's patent-pending classification system automatically identifies and classifies all APs and stations connected to the network. The system works by comparing traffic seen in the air with traffic seen on the wire. When a match is found, it is known with certainty that the device belongs to the local network rather than a neighboring network. This avoids false alarms for the administrator, because only true rogue devices are classified as such. Detecting and Disabling Rogue APs Aruba's classification algorithms allow the system to accurately determine who is a threat and who is not. Once classified as rogue, these APs can be automatically disabled. Administrators are also notified of the presence of rogue devices, along with their precise physical location on a floorplan, so that they may be removed from the network. Denial of Service and Impersonation Protection Wireless networks, by their nature, make an attractive target for denial of service attacks. Such attacks include software that floods the network with association requests, attacks that make a laptop look like thousands of APs, and deauthentication floods. Aruba mobility controllers equipped with the Aruba WIP module maintain signatures of many different wireless attacks and are able to block them so service is not disrupted. Advanced Denial of Service (DoS) protection keeps enterprises safe against a variety of wireless attacks, including association and de-authentication floods, honeypots and AP and station impersonations. Based on location signatures and client classification, Aruba access points will drop illegal requests and generate alerts to notify administrators of the attack.
