Abstract

The invention provides a virus protection method and device, equipment and a storage medium, and the method is applied to intrusion prevention equipment, and comprises the steps: identifying the typeof a transmission file in a network; if the transmission file is an executable file, caching a plurality of received data packets of the transmission file one by one before caching the transmission file completely, and calculating an MD5 value of the cached transmission file based on the cached data packets; judging whether the calculated MD5 value is successfully matched with a preset MD5 table entry or not, wherein the MD5 table entry records the MD5 value of the known virus file; and if the matching is successful, blocking the transmission file. According to the embodiment of the invention,the cache number of the non-executable files is reduced, the virus protection efficiency is improved, real-time blocking of the virus files is realized, and the performance of the intrusion prevention equipment is improved.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a virus protection method, device, equipment and storage medium. Background technique [0002] With the continuous development of network technology, the security of the network has also received great attention. The emergence of viruses has greatly reduced the security of network transmission data. In order to block the spread of viruses, various virus protection technologies have been continuously produced. [0003] At present, the anti-virus technology applied on IPS (Intrusion Prevention System, intrusion prevention system) equipment is a file-based virus protection technology. This technology caches the transmitted files in the network completely, and then uses the virus detection engine to check the integrity of the cache. The file is checked for viruses. [0004] In the above technical solution, the file-based virus protection technology needs ...
