With the rapid development of computer network technology, network security issues have become increasingly prominent in the face of various users. According to the data obtained by the author, nearly 20% of users on the Internet have suffered from hackers. Although hackers are so rampant, the network

Now you know how to implement account security and have established an effective authentication mechanism. Next, we will implement access control in security. Access control must be implemented locally and remotely. Files can be accessed locally or remotely over the network.

WirelessNetworkSecurityAlthough the name seems to be a security option for wired networks, this is not the case. The WEP standard has been created in the early stages of wireless networks and is designed to become a necessary security protection layer for WLAN in Wireless LAN. However, the performance of WEP is undoubtedly disappointing. It is rooted in design defects. In WEP systems, data transmitted over
