Security
The SMC2555W-AG is configured by default as an “open
system,” which broadcasts a beacon signal including the
configured SSID. Wireless clients can read the SSID from the
beacon, and automatically reset their SSID to allow immediate
connection to the nearest access point.
To improve wireless network security, you have to implement two
main functions:
• Authentication: It must be verified that clients attempting to
connect to the network are authorized users.
• Traffic Encryption: Data passing between the access point and
clients must be protected from interception and evesdropping.
For a more secure network, the access point can implement one
or a combination of the following security mechanisms:
• Wired Equivalent Privacy (WEP) page 5-52
• IEEE 802.1x page 5-16
• Wireless MAC address filtering page 5-14
• Wi-Fi Protected Access (WPA) page 5-57
