Abstract

The invention relates to a data sending method based on WAF. The method comprises the steps: acquiring a traffic message sent by a data sending end; based on a preset known message matching rule and a preset HTTP message matching rule, extracting a known message and an unknown HTTP message in the flow message; and carrying out attack message detection on the known message and the unknown HTTP message, and sending the known message and the unknown HTTP message passing the attack message detection to a data receiving end. Through the method and the device, the problems that data cannot be normally transmitted and a network cannot be connected due to the fact that some unknown messages cannot be identified in the prior art are solved, not only can the known messages be subjected to identifying and data transmission, but also the unknown messages can also be subjected to identifying and data transmission, and the normal connection of the network can be ensured while the security of the traffic message is ensured.

Description

technical field [0001] The present application relates to the technical field of computer networks, and in particular to a WAF-based data transmission method, device, electronic device and storage medium. Background technique [0002] At present, with the development of technology and people's dependence on the network, Web (World Wide Web) applications are becoming more and more abundant. Due to the powerful computing power, processing performance and high application value of the Web, it has gradually become the target of criminals' attacks and cracks. , such as structured programming language injection, web page tampering, network Trojan horses and other threats and attack methods often occur. Based on this, people invented a website application-level intrusion prevention system (Web Application Firewall, WAF for short) as a method to identify abnormal attack traffic , usually by matching against an abnormal traffic rule set to identify abnormal traffic. [0003] Because...
