Problems solved by technology

Although the firewall rules can be successfully updated by applying the above method, artificial copying of new firewall rules usually has a lag, that is, the real-time performance of the above firewall rule update method is poor, especially when the attack methods are diverse and changeable. The disadvantage of poor real-time performance of updating firewall rules is more prominent

Abstract

The invention discloses a Web application firewall rule updating method, device and system. The method disclosed by the embodiment of the invention comprises the following steps: firstly, a Web server sends a rule synchronization request for a target service to a rule management server; and then, the rule management server verifies whether a target version number in the rule synchronization request is consistent with the latest version number, wherein the target version number is the version number, which is locally stored by the Web server, of a first firewall rule corresponding to the target server; and the latest version number is the version number, which is stored in a local hard disk of the rule management server, of the latest firewall rule corresponding to the target service; if the target version number and the latest version number are inconsistent, a second firewall rule is sent to the Web server; the Web server receives the second firewall rule sent by the rule management server; and the first firewall rule is updated as the second firewall rule. By use of the technical scheme provided by the embodiment of the invention, the updating of the firewall rule can be realized in real time.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method, device and system for updating rules of a Web application firewall. Background technique [0002] At present, the Web application firewall technology is mainly implemented through a Web Application Firewall (WAF), and WAF represents a new type of information security technology to solve the security problems of Web applications. [0003] In the prior art, the WAF running in the web server mainly uses pre-established firewall rules to filter external requests to achieve defense protection, and the pre-established firewall rules are mostly stored locally on the web server in the form of files. When there is a firewall rule update, it is necessary to manually copy the new firewall rule to the local Web server, so as to realize the update of the firewall rule locally stored in the Web server. Although the firewall rules can be successfully updated by applying the abov...
