Abstract

The invention relates to smart agreement analytical methods and devices used for intruding detection defense (IDS / IPS) and audit products. The purpose of the invention is to provide an agreement not to rely solely on the static ports and matching agreement characteristics of intelligent field protocol analysis technology and analytical format of the agreement is automatically adjusted in different versions of the software and gives accurate results, which enhanced the accuracy of the analysis of the agreement. The invention consists of three major steps: the establishment of agreements features model; agreement recognition; intelligent analysis of that agreement. This invention solved the traditional IDS / IPS products for the non-standard ports or did not have static characteristics of field data packet network protocol identification of problems but for some applications or different versions of the agreement, such as the reasons for the analytical results can provide automated error rectification work.

Description

technical field

[0001] An intelligent protocol analysis method and device of the present invention relate to a network with switching as a function, and is a communication control / processing method and device characterized by protocol, preventing data from being fetched from a data transmission channel without permission. It is an intelligent protocol analysis method and device in an intrusion detection / protection system (Intrusion Detection / Protection System, IDS / IPS) and an audit product. Background technique

[0002] As an important means of network security protection, intrusion detection / prevention system (IDS / IPS) is usually deployed at the entrance of the key network / network boundary, and captures the packet data flow in the network or in and out of the network in real time and conducts intelligent comprehensive analysis to detect possible intrusion behavior and block it in real time. Application layer protocol deep analysis technology is widely used in current mains...
