Select an answer to reveal the explanation.
Short Explanation
Standing outside a shop, you can still read the neon sign and watch people knock on the door — you don't need to walk inside. Passive Wi-Fi listening is like that: beacons and probes leak a lot of management gossip before you ever associate.
Full Explanation
Passive reconnaissance on 802.11 commonly observes management and control signaling such as beacons and probe frames without association. That traffic can reveal SSIDs, capabilities, and related metadata even when data frames are encrypted. Association and key establishment are required for many protected data paths, but they are not prerequisites for seeing unprotected management information on the air.
