Abstract

The invention provides a network protection method and a network protection device. The method comprises the steps of when receiving a message, judging that whether the protocol type of a message is a preset type; if yes, recombining the message with other messages of a session to which the message belongs, thus obtaining a recombined message flow; judging that whether message information matched with the recombined message flow exists in a preset virus information library which comprises correspondence between different message information and virus types; if yes, according to the virus type corresponding to the message information of the recombined message flow, implementing antivirus treatment on the recombined message flow. With the application of the method and device provided by the embodiment of the invention, the messages in the same session are recombined to obtain a recombined message flow, the recombined message flow is subjected to virus checking as a whole, thus being capable of avoiding that a virus cannot be accurately detected as the virus exists in the messages in a cross-packet, disordered or sliced manner, and thereby the accuracy of virus detection is improved, the false report rate or missing report rate is reduced, and guarantees are provided for network security.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network protection method and device. Background technique [0002] Network applications have penetrated into people's life and work, and various network viruses are also emerging one after another, especially some important network nodes are facing the threat of a large number of network viruses all the time. Network devices in related technologies, such as IPS (Intrusion Prevention System, intrusion prevention system) devices, can implement virus detection on a single packet to achieve network protection. However, based on this virus detection mechanism, if the same session In this session, the session includes multiple packets, and viruses exist in multiple packets through cross-packet, out-of-sequence, or fragmentation, and the network device only performs virus detection on a single packet, so it will not be able to accurately identify the virus. False positives or...
