[. . . ] Wired Equivalent Privacy (WEP) provides a basic level of security, preventing unauthorized access to the network and encrypting data transmitted between wireless clients. WEP uses static shared keys (fixed-length hexadecimal or alphanumeric strings) that are manually distributed to all clients that want to use the network. - TKIP ­ Use Temporal Key Integrity Protocol (TKIP) keys for encryption. WPA specifies TKIP as the data encryption method to replace WEP. TKIP avoids the problems of WEP static keys by dynamically changing data encryption keys. - AES ­ Use Advanced Encryption Standard (AES) keys for encryption. WPA2 uses AES Counter-Mode encryption with Cipher Block Chaining Message Authentication Code (CBC-MAC) for message integrity. The AES Counter-Mode/CBCMAC Protocol (AES-CCMP) provides extremely robust data confidentiality using a 128-bit key. Use of AES-CCMP encryption is specified as a standard requirement for WPA2. Before implementing WPA2 in the network, be sure client devices are upgraded to WPA2-compliant hardware.

IEEE 802. 1X is a standard framework for 3-6 Wireless Utility Configuration network access control that uses a RADIUS server on the local network for user authentication. The 802. 1X standard uses the Extensible Authentication Protocol (EAP) to pass user credentials (either digital certificates, usernames and passwords, or other) from the client to the RADIUS server. Figure 3-6. Profile - 802. 1X · EAP Method ­ Select an 802. 1X authentication method. - PEAP ­ Protected Extensible Authentication Protocol. PEAP transport securely sends authentication data by using tunneling between PEAP clients and an authentication server. PEAP can authenticate wireless LAN clients using only server-side certificates, thus simplifying the implementation and administration of a secure wireless LAN. - TLS / Smart Card ­ Transport Layer Security. Provides for certificate-based and mutual authentication of the client and the network. It relies on client-side and server-side certificates to perform authentication and can be used to dynamically generate user-based and session-based WEP keys to secure subsequent communications between the WLAN client and the access point. - TTLS ­ Tunneled Transport Layer Security. [. . . ] Power Saving Mode -- The power saving status of the connected station. 5-7 AP Mode Configuration Event Log The event log page displays system messages generated during system operation. The logged messages can serve as a valuable tool for isolating Wireless USB Adapter and network problems. Figure 5-5.
