Answer: D

Explanation:

An application firewall, also known as a web application firewall (WAF) or application-level firewall, is designed to protect web applications from various attacks, such as cross-site scripting (XSS), SQL injection, and distributed denial-of-service (DDoS) attacks. It analyzes the incoming traffic and blocks malicious requests, protecting the application and its underlying infrastructure. Encryption, speed enhancement, and vulnerability scanning are not primary functions of an application firewall.
