SSID Last modified: Tuesday, April 10, 2007
Short for service set identifier, a 32-character unique identifier attached to the header of packets sent over a WLAN that acts as a password when a mobile device tries to connect to the BSS. The SSID differentiates one WLAN from another, so all access points and all devices attempting to connect to a specific WLAN must use the same SSID. A device will not be permitted to join the BSS unless it can provide the unique SSID. Because an SSID can be sniffed in plain text from a packet it does not supply any security to the network. An SSID is also referred to as a network name because essentially it is a name that identifies a wireless network.
Getting Phished: Why SSID Spoofing (Still) Matters Phony access points (APs) that use spoofed service set identifiers (SSIDs) to lure wireless users are nothing new. Minimizing WLAN Security Threats Most wireless LANs do not invoke adequate security measures to guard against attacks. Learn what security threats exist for wireless LANs as the basis for deploying effective security measures. What SSID is Right for You? The problem with using the default SSID is that some confusion might result if a company or home owner next to you sets up a wireless LAN with the same vendor's access points.
