What is 'SSID broadcasting' and does disabling SSID broadcast provide meaningful security for a Wi-Fi network?

• A.SSID broadcast is a legal requirement for Wi-Fi networks in public spaces
• B.SSID broadcasting means the AP includes the network name in beacon frames; disabling it provides minimal security because the SSID is still visible in probe requests and probe responses when clients try to connect, and tools like Kismet or Wireshark trivially reveal the hidden SSID, while legitimate users have trouble connecting
• C.Disabling SSID broadcast encrypts the network name using WPA3
• D.SSID broadcast must be disabled for 802.1X authentication to work correctly
