Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0039] For ease of understanding, the words appearing in the embodiments of the present application are explained below.

[0040] Feature rules: including the corresponding relationship between features and processing operations on traffic; if the traffic matches the features in a feature rule, the traffic matches the feature rule.

[0041] Currently, if figure 1 The shown network includes a client 101, a security device 102, and a server 103; in order to prevent various attack tra...

Abstract

The embodiment of the invention provides a characteristic rule enabling method and device. The method comprises the following steps: safety equipment receives a traffic, and sends a traffic mirror image to traffic learning equipment if the traffic is not matched with any enabled characteristic rule of the safety equipment; the traffic learning equipment detects a first characteristic rule matchedwith the traffic from enabled characteristic rules of the traffic learning equipment, and sends an enabling command for the first characteristic rule to the safety equipment, wherein the enabling command is used for instructing the safety equipment to enable the first characteristic rule; and the safety equipment receives the enabling command and enables the first characteristic rule according tothe enabling command. The method and device provided by the embodiment of the invention has the advantages that effects on the processing of normal services can be reduced, and the network safety canbe improved.

Description

technical field [0001] The present application relates to the technical field of network security, in particular to a method and device for enabling feature rules. Background technique [0002] With the development of network technology, there are more and more types of network applications and operating systems, and the update speed of network applications and operating systems is getting faster and faster, which leads to more and more system vulnerabilities. [0003] In order to prevent various attack traffic generated through system vulnerabilities and improve network security, security devices, such as DPI (Deep Packet Inspection, deep packet inspection) devices, are equipped with more and more characteristic rules matching attack traffic. Rules are used to detect attack traffic. [0004] With the increase of feature rules configured on the security device, if all the feature rules configured are directly enabled, the business processing performance of the security devi...
