The goal of each security management plan is to make the intrusion process more complex, require more time, and be caught in a higher probability to guard against potential intruders or attackers. Even if you are installing fences in your yard, lock the door, keep a dog in the yard, put a latch on the window and the door, install the burglar, and you
methods to protect the security of the wireless LAN, there is also a more effective protection method, that is, to encrypt the wireless transmission signal, this method often has a high security protection effect.
Currently, there are two common encryption methods for wireless node devices: WEP encryption and WPA encryption. Among them, WEP technology is also called Peer-to-Peer
