ENTERPRISE-CLASS SECURITY SOLUTION
Designed with enterprise-class security requirements in mind, the Cisco
Aironet 802.11a/b/g Wireless CardBus Adapter uses the 802.1X standard for
port-based network access. A full array of Extensible Authentication Protocol
(EAP) types for user-based authentication, together with enterprise-caliber
Advanced Encryption Standard (AES) encryption, provide full 802.11i support.
The adapter supports WPA2-the Wi-Fi Alliance certification for interoperable,
standards-based wireless LAN security.
The Cisco Aironet 802.11a/b/g Wireless CardBus Adapter supports the most
common 802.1X authentication types, including EAP-Flexible Authentication via
Secure Tunneling (EAP-FAST), Cisco LEAP, EAP-Transport Layer Security
(EAP-TLS), Protected Extensible Authentication Protocol-Generic Token Card
(PEAP-GTC), and PEAP-Microsoft Challenge Handshake Authentication Protocol
version 2 (PEAP-MSCHAPv2). A wide selection of RADIUS servers, such as the
Cisco Secure Access Control Server (ACS) and Cisco Access Registrar server,
can be used for enterprise-class centralized user management that includes:
• Strong, mutual authentication to help ensure that only legitimate clients
associate with legitimate and authorized network RADIUS servers via authorized
access points
• Dynamic per-user, per-session encryption keys that automatically change on a
configurable basis to protect the privacy of transmitted data
• Stronger encryption keys provided by Temporal Key Integrity Protocol (TKIP)
enhancements such as message integrity check (MIC), per-packet keys via
initialization vector hashing, and broadcast key rotation
• RADIUS accounting records for all authentication attempts
