What is the primary purpose of Fortinet's Web Application Firewall (WAF)?

The primary purpose of Fortinet's Web Application Firewall (WAF) is to protect web applications from various types of attacks. WAFs are specifically designed to safeguard web applications by filtering and monitoring HTTP traffic between a web application and the Internet. They are crucial in defending against common threats such as SQL injection, cross-site scripting (XSS), and other vulnerabilities that can be exploited by attackers.

WAFs implement rules and policies to detect and block potentially harmful traffic while allowing legitimate user requests to the web applications. This functionality is essential for maintaining the security and integrity of web applications, ensuring that sensitive data is protected and that service availability is maintained.

The other options pertain to different functionalities that do not relate specifically to the role of a WAF. Monitoring file storage efficiency and managing internal databases are not core features of a WAF, as these tasks are handled by storage management or database management systems. Analyzing network throughput is more aligned with network performance monitoring rather than web application security, emphasizing the focus of the WAF's primary purpose.
