(Nowadays, more and more units use wireless local area networks. We can easily find a lot of wireless Internet access signals by walking around the office building with laptops at will. However, there are more or less security risks in these wireless Internet access signals. An illegal attacker who has a little understanding of the wireless network can easily obtain the private information in the local area network of the unit with the help of the wireless network through some simple operations. In that case A wireless network without any security precautions will naturally become a "channel" for information leakage. So how can we maintain the security of the wireless local area network after all, and refuse the network to become a "channel" for external leakage? Originally, we can adopt a number of restrictive methods to prevent illegal attackers from stealing private information on the network through the wireless local area network at will.)
