1. Service Set Identifier (SSID): This is a unique identifier of 32 byte length added to each header of the packets transmitted through the wireless LAN, when wireless devices access BSS (Basic Service Set), they are used as if they were a password. SSID distinguishes one wireless LAN from another wireless LAN, so all APs or wireless devices to access a specific wireless LAN must match SSID.
  2. MAC Address Authentication: Every LAN card on a computer or mobile device has a medium access control (MAC) address. The authentication method using the unique number system enables the use of a wireless network only by a device registered in a wireless AP.
  3. Sniffing: As a cyber hacking technique, sniping means overhearing packet exchanges of other opponents on the network. In short, the process of eavesdropping on network traffic can be called sniping.
