There are many web application firewall products on the market. What functions do WAF products have to meet the needs of domestic customers for web server protection? Customers get bogged down in a choice of features, performance, and ease of use. Whether it is a domestic or foreign WAF product, in addition to the most basic performance requirements of the HTTP protocol, the appropriate architecture and size must also be considered. The first thing to evaluate is how the web application on the current network is constructed: is the application already behind a reverse proxy system? If so, and the enterprise wants to continue using the reverse proxy architecture, consider a WAF that supports this need. A reverse proxy system is ideal if the Enterprise Edition requires the WAF to terminate SSL connections in order to inspect packet content.
In addition, look at the functional requirements of WAF. There are the following points: 1. The enterprise version of the WAF product must have the protection function against cross-site request forgery (CSRF) attacks. 2. It should have the protection function against Web attacks, such attacks mainly include SQL injection attacks and XSS cross-site attacks. 3. WAF products should have the protection function of Web malicious code. 4, with Web application compliance function. Application compliance means that various behaviors performed by the client or the web server meet the specified requirements set by the user.
