Abstract

An embodiment of the invention discloses a network intrusion prevention method, device and system and a computer readable storage medium. The method includes: receiving a data packet, and subjecting the received data packet to protocol analysis; performing fire wall policy matching on the data packet subjected to protocol analysis, and processing the data packet by a matched fire wall policy; recognizing an application corresponding to the data packet, and processing the data packet according to an application access control policy corresponding to the recognized application; subjecting the data packet to content analysis, adopting a content obtained by analysis to obtain a content safety protection policy by matching, and processing the data packet by the content safety protection policy.After protocol analysis of the data packet, protocol and port detection is performed according to the fire wall policy, then application layer information is deeply read on the basis of application feature code recognition, and an application type is determined by comparison of analyzed application information with a background feature library.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, and in particular to a network intrusion prevention method, device, system and computer-readable storage medium. Background technique [0002] With the rapid development of the Internet and the explosion of various applications, enterprises are faced with risks brought by vulnerabilities in commonly used applications. [0003] Network communication is no longer solely dependent on store-and-forward applications such as e-mail, as it once was, but has expanded to include real-time collaboration tools, Web 2.0 applications, instant messaging (IM) and P2P applications, voice over IP telephony (VoIP), streaming media and conference calling, all of which pose potential risks. Many enterprises fail to distinguish between applications used on the network that have a legitimate business purpose and those that are not critical (those that consume bandwidth or pose danger). Malware and cybe...
