Security risks of wireless networks (1)

Wireless network technology provides the convenience and mobility of the network, but it also brings security risks to your network. Because the wireless local area network transmits data through wireless signals, wireless signals cannot control the spread of data in the space after being transmitted, and thus are easily intercepted by undesirable receivers. Unless visitor and device authentication and authorization mechanisms are sound enough, any user with a compatible wireless network card can access the network.

If valid data encryption is not performed, wireless data is sent in plaintext, in this way, anyone within the valid signal distance of a wireless access point can detect and receive all data from and from the wireless access point. Non-fast customers can easily access the network through wireless client devices within the range covered by wireless LAN signals without attacking the internal wired network. As long as the security mechanisms related to the security of the wireless LAN can be cracked, the local network of the company can be completely attacked. Therefore, wireless LAN is inherently insecure because it transmits data through wireless signals.
