Web applications generally use form-based authentication (as shown in Figure). The processing logic is to pass the user name and password submitted in the form to the background database for query, determine whether the authentication is successful Based on the query results. For web applications with LAMP architecture, PHP is used for processing logic, and MySQL is used for background databases. In this process, due to poor processing, many serious vulnerabilities may occur. Apart from weak pas

WAF Web Application FirewallThe Web application firewall is a product that is specifically designed to protect Web applications by executing a series of security policies for Http/https.Unlike traditional firewalls, WAF works at the application layer, so there is a natural technical advantage to Web application protection. Based on a deep understanding of the business and logic of Web applications,
Now, the market exists a large number of true and false Web application firewall products, the user's understanding of it is not clear enough, coupled with the industry's lack of Web application firewall measurement standards, Web application Firewall evaluation of the good or bad becomes very difficult.
In fact, to choose a good Web application firewall is not difficult, the following aspects can be examined:
1. Attack interception capability
