How to Use this User Guide The user guide to the CompactFlash Card has been designed to make understanding networking with the Access Point easier than ever. [. . . ] Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is "linksys". ) Hackers know these defaults and can check these against your network. Change your SSID to something unique and not something related to your company or the networking products you use. Change your SSID regularly so that any hackers who have gained access to your wireless network will have to start from the beginning in trying to break in. MAC Address filtering will allow you to provide access to only those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with a random MAC Address. Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless security concerns. Again, this can only provide enough security to make a hacker's job more difficult. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. Pre-Shared Key gives you a choice of two encryption methods: TKIP (Temporal Key Integrity Protocol), which utilizes a stronger encryption method and incorporates Message Integrity Code (MIC) to provide protection against hackers, and AES (Advanced Encryption System), which utilizes a symmetric 128-Bit block data encryption. RADIUS (Remote Authentication Dial-In User Service) utilizes a RADIUS server for authentication and the use of dynamic TKIP, AES, or WEP. Important: Always remember that each device in your wireless network MUST use the same encryption method and encryption key or your wireless network will not function properly. Appendix B: Wireless Security Security Threats Facing Wireless Networks 29 Wireless-G CompactFlash Card WPA Pre-Shared Key. If you do not have a RADIUS server, select the type of algorithm, TKIP or AES, enter a password in the Pre-Shared key field of 8-64 characters, and enter a Group Key Renewal period time between 0 and 99, 999 seconds, which instructs the Router or other device how often it should change the encryption keys. (This should only be used when a RADIUS server is connected to the Router or other device. ) First, select the type of WPA algorithm, TKIP or AES. Enter the RADIUS server's IP Address and port number, along with a key shared between the device and the server. Last, enter a Group Key Renewal period, which instructs the device how often it should change the encryption keys. (This should only be used when a RADIUS server is connected to the Router or other device. ) First, enter the RADIUS server's IP Address and port number, along with a key shared between the device and the server. Then, select a WEP key and a level of WEP encryption, and either generate a WEP key through the Passphrase or enter the WEP key manually. Implementing encryption may have a negative impact on your network's performance, but if you are transmitting sensitive data over your network, encryption should be used. These security recommendations should help keep your mind at ease while you are enjoying the most flexible and convenient technology Linksys has to offer.
