Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] The present invention identifies viruses by analyzing the network connection characteristics of received data packets on the firewall, detects network worms in real time, locates computers infected with worms in the local area network, and suppresses network worms in time by automatically setting blocking rules Spread. A network worm real-time detection and automatic suppression module is added to the firewall device constructed according to the method of the present invention, and the module completes the functions of real-time detection, alarm and automatic suppression of network worms. see Figure 4 , the module is located between the network filtering module and the routing and forwarding module in the firewall network protocol stack. The data packets received from the network interface are filtered by the network filtering module, and the ...

Abstract

The present invention relates to a network worm virus real-time detection method. It is characterized by that it utilizes the data packet received on flame-proof wall and makes said data packet undergo the processes of network connection and characteristic analysis to implement identification of virus, so that it can real-time detect the network worm.

Description

Technical field: [0001] The invention relates to the technical field of firewalls for computer network applications, in particular to a method for detecting network worms in real time. Background technique: [0002] A network worm is a malicious program that seriously threatens the security of information systems, and has the functions of self-replication and automatic propagation. A large number of rapid self-replication and propagation of network worms will occupy a large amount of network resources, cause network congestion or even network paralysis, and eventually cause huge economic losses. [0003] There are currently three main methods for preventing and controlling network worms. The first method is to prevent worms by installing system patches: since worms mainly attack the vulnerabilities of the system, after the outbreak of worms, the relevant system developers release the latest system patches, which can be automatically upgraded or manually installed by users t...
