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
IEEE 802.11i/WPA2 AES support

ENHANCED CLIENT NETWORK MANAGEMENT FEATURES

A new and improved set of client utilities includes the Cisco Aironet Desktop Utility, System Tray Utility, and Client Administration Utility. Together, these utilities provide an intuitive graphical user interface (GUI) for easy configuration, monitoring, and management of the Cisco Aironet 802.11a/b/g Wireless CardBus Adapter. Enhanced client network management features include:

Profile manager-Allows users to create specific profile settings for various environments, making it simple for telecommuters and business travelers to move from one environment to another (Figure 2).
Customized profile settings-Lets users individually select the channel, service set identifier (SSID), Wired Equivalent Privacy (WEP) key, and authentication method for different locations.
Cisco LEAP authentication status screen-Provides status updates regarding the Cisco LEAP authentication process.
Auto-selection of profiles, including those configured for EAP authentication, provides automatic selection of established profiles without requiring storage of the EAP username and password in the profile.
System tray icon-Provides easy access to wireless LAN connection information and one-click access to common actions such as manual selection a profile or turning the radio on or off.
Cisco Aironet Client Monitor-Provides a subset of Cisco Aironet Desktop Utility features, such as status information about the client adapter and access to basic tasks (selecting a profile, for example). This application runs from the system tray icon.
Troubleshooting utility-Provides step-by-step details on the process of connecting to an access point, as well as highlights on why a connection failed (Figure 3).
Support for the most popular enterprise operating systems-Windows XP and Windows 2000.

Figure 2. Cisco Aironet Desktop Utility (Profile Management) Screen

A Cisco Aironet Client Adapter installation wizard for Windows is provided for easy installation of the client firmware, drivers, and utilities. The wizard offers several installation offers-install client utilities and driver; install driver only; or make driver installation diskette(s). For ease of use, the installation wizard image file is a self-extracting (.exe) file.
