SSID
Service Set Identifier — the broadcast name that identifies a wireless network to clients.
A Service Set Identifier is a case-sensitive name of up to 32 characters that identifies a wireless network and is advertised in 802.11 beacon frames so clients can detect and join it. Access points sharing one SSID form an ESS (Extended Service Set), enabling seamless roaming. For the exam, distinguish the SSID from the BSSID: the BSSID is the MAC address of a specific access point radio, while the SSID is the human-readable network name. Disabling SSID broadcast is weak obscurity — clients still reveal the SSID in probe requests, making it discoverable with a wireless analyzer, so it cannot replace strong authentication like WPA3.
