WAF Generation background

While web applications are becoming more and more abundant, web server has gradually become the main attack target with its powerful computing power, processing performance and high value. SQL injection, web page tampering, web page hanging horse and other security events occur frequently. Enterprises and other users generally use firewall as the first line of defense of the security system. However, in reality, there are various security problems in web servers and applications, and with the progress of hacker technology, it becomes more difficult to prevent, because these problems are difficult to detect and block by ordinary firewall, resulting in WAF (web application protection system). Web application firewall (WAF) represents a new type of information security technology to solve the web application security problem of traditional devices such as firewall. Different from the traditional firewall, WAF works in the application layer, so it has inherent technical advantages for web application protection. Based on the deep understanding of web application business and logic, WAF detects and verifies the content of various requests from web application clients to ensure their security and legitimacy, and blocks illegal requests in real time, so as to effectively protect various websites.
