Embodiment Construction

[0010] This network intrusion security defense system, according to the intruder's attack steps, sets up multiple checkpoints, and starts to defend the system from the first step of intrusion, including intrusion port scanning detection, camouflage system service, traditional packet filtering firewall, WEB intrusion prevention module, Vulnerability library module, intrusion feature library module, through the organic combination of these functional modules, and simple configuration and installation on the WEB server, it can play a comprehensive system protection role. After installation and operation, it will start to monitor the security status of the system. If any abnormality is found, the attack will be blocked in time, and an email will be sent to notify the system administrator. In the present invention, the creative data check-in and check-out judgment comes from the filter program subsystem of WEB request legitimacy, which is composed of data check-in and data check-out...

Abstract

The present invention has several guard measures to defend network invasion of known and unknown modes. The guard system consists of invasion port scanning, camouflage system service, WEB invasion defending firewall, traditional package filtering firewall and other subsystem. The guard system features its program-filtering subsystem, in which the validity of request from WEB is judged through thedata sorting based on the data hole base and invasion characteristic base. The program-filtering subsystem can be used to filter out invasion of both known and unknown hole attack. These functional modules may be configured and installed to WEB server to protect the system comprehensively.

Description

Technical field: [0001] The present invention relates to a network security protection method, specifically relates to an effective combination of intrusion detection and firewall technology, so as to detect intrusion scanning, camouflage system services, and prevent hacker intrusion. Especially in the detection method of hacker intrusion, the program judgment method of "judging whether the client's request is an intrusion behavior through the process and results" has been created, which can not only effectively prevent intruders from using known attack methods to attack the system , and can prevent intruders from using unknown attack methods to attack the system as a security protection method. Background technique: [0002] In recent years, the development of computer networks has been very rapid, and the number of domestic Internet users has increased rapidly. Up to now, the number of domestic Internet users has reached 20 million, and the types of network services are be...
