Method for improving security of server by adopting IP strategy packet

Abstract

The invention discloses a method for improving the security of a server by adopting an IP strategy packet, which comprises the following steps of: S010, allocating a number to a client, and respectively registering an ID (Identity) and a secret key in the client and a trusted authorization system; S020, mutually recognizing the client and the trusted authorization system based on a protocol; S030,enabling the client to perform authentication, and if the authentication is passed, enabling the trusted authorization system to take the IP address of the client as a parameter, filling an IP strategy packet and sending the IP strategy packet to a corresponding server; S040, analyzing and processing the IP strategy packet by a preposed IP filter of the server, and recording the IP address of thelegal client; and S050, if the authentication of the client and the trusted authorization system is normal, enabling the IP packet from the client to communicate with the server. According to the method, remote unauthorized access and unauthorized internet surfing of the server are shielded to the maximum extent, and the problems of random connection of an internal Trojan horse program to an external network, remote malicious attacks, connection and the like are reduced.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a method for improving server security by using IP policy packets. Background technique [0002] With the evolution of the market and the advancement of technology, the security requirements of the system are getting higher and higher. However, the server often needs to respond to a request from an unknown IP address, and there may be a Trojan horse program that has been put in for a long time on the server. How to achieve high security while ensuring the convenience of remote access is a difficult problem. [0003] In order to save trouble, it is usually left to its own devices, otherwise, the firewall must be temporarily modified and configured manually. Firewalls don't necessarily work sometimes. For example, the Trojan horse program located on the server is difficult to find, but it can access the external network at will, and the security problem of the system is very ser...
