Safety protection method of network feedback host computer

Abstract

The present invention discloses a safety protection method of network feedback host computer, wherein the host computer is mainly composed of a hardware device and PC terminal software. The method of the invention comprises the following steps: firstly executing strategy configuration and transmission, then initializing the network protection hardware for obtaining the trustable IP corresponding with the trustable domain name; then actualizing monitoring network connection based on the configuration file formed by the former two steps for realizing accessing control; than detecting all data packages flowing over the system and the trustable address, executing deep analysis to the data packages, executing package filtering based on a preset regulation; afterwards, auditing the network behavior; and finally perfecting the strategy configuration and updating the configuration file. The method can ensure the safety of computer terminal information to a certain extent at a state that the computer terminal encounters the hostile attack of Trojan, virus, etc. Furthermore the method has high-effective strategy and auditing functions for causing that the user can timely and comprehensively manage and configure a network safety protection system and master all network connection and behavior of the computer terminal.

Description

Technical field [0001] The invention relates to a security protection method for a network feedback host, belonging to the technical field of network information security. Background technique [0002] While the rapid development of the Internet has improved work efficiency, it has also brought about an increasingly serious problem - network security. People study various network security protection methods to protect computers and information resources on the network and resist various attacks by hackers. Firewall technology is an applied security protection technology based on modern communication network technology and information security technology. It is more and more used in the interconnection environment of private network and public network, especially Internet network. With the rapid development of the Internet, firewall products have sprung up in just a few years, forming an industry soon. [0003] A firewall refers to a combination of a series of components se...

AI Technical Summary

Problems solved by technology

The disadvantage is that if malicious codes such as viruses use a deeper operating system kernel mechanism than the host firewall monitoring technology, the host firewall cannot achieve a good monitoring effect

Network firewalls can intercept all passing network data packets for detection and processing, but limited by firewall rules, some viruses that use deception, camouflage and other technologies for network connection and data transmission cannot be effectively detected
