企业级的安全解决办法
Cisco为Aironet IEEE802.11 a/b/g无线PCI网卡设计了企业级的安全标准。使之其运行在无线最安全的802.1X标准成为可能。the Cisco Wireless Security Suite takes advantage of the Extensible Authentication Protocol (EAP) framework for user-based authentication (Figure 2). This solution also supports WPA, the Wi-Fi Alliance specification for interoperable, standards-based wireless LAN security.
The Cisco Aironet 802.11a/b/g Wireless PCI Adapter supports the most common 802.1X authentication types, including Cisco LEAP, Extensible Authentication Protocol Transport Layer Security (EAP-TLS), Protected Extensible Authentication Protocol (PEAP-GTC), and Protected Extensible Authentication Protocol Microsoft Challenge Handshake Authentication Protocol Version 2 (PEAP-MSCHAP V2). A wide selection of RADIUS servers, such as the Cisco Secure Access Control Server (ACS) and Cisco Access Registrar (AR) server, can be used for enterprise-class centralized security and management that includes:
·Strong, mutual authentication to 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, such as message integrity check (MIC), per-packet keys via initialization vector hashing, and broadcast key rotation, provided by Temporal Key Integrity Protocol (TKIP) enhancements
·RADIUS accounting records for all authentication attempts
·Ready for Advanced Encryption Standard (AES) Support

A new and improved set of client utilities includes the Aironet Desktop Utility (ADU), Aironet System Tray Utility (ASTU), and Aironet Client Administration Utility (ACAU). Together, these utilities provide an intuitive graphical user interface (GUI) for easy configuration, monitoring, and management of the Cisco Aironet 802.11a/b/g PCI Adapter. Enhanced client network management features include:
·Profile Manager—Allows users to create specific profile settings for various environments, such as the office and home, making it simple for telecommuters and business travelers to move from one environment to another (Figure 4)
·Customized profile settings—Lets users individually select channel, service set identifier (SSID), Wired Equivalent Privacy (WEP) key, and the authentication method for different locations
·Cisco LEAP authentication status screen—Provides status updates regarding the Cisco LEAP authentication process
·Auto-selection of profiles, including Cisco LEAP profile—Provides automatic selection of established profiles, including Cisco LEAP profile without requiring the storage of Cisco LEAP 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 the manual selection of a profile or turning the radio on/off.
·Aironet Client Monitor—Provides a subset of Aironet Desktop Utility features such as status information about the client adapter and access to basic tasks such as selecting a profile. This application runs from the system tray.
·Troubleshooting Utility—Provides step-by-step details on the process of connecting to an access point with highlights on why a connection failed. (Figure 5)
·Support for the most popular enterprise operating systems—Windows XP and Windows 2000
