Web application firewalls (WAFs) are designed primarily to protect applications from common attacks like: Response:

Syn floods are network-layer (Layer 4) Denial of Service (DoS) attacks typically mitigated by network firewalls or specialized DDoS protection services, not primarily by WAFs.

Ransomware is malicious software that encrypts data and demands a ransom; WAFs protect the web application itself, not endpoint systems from ransomware infection.

Web Application Firewalls (WAFs) operate at the application layer (Layer 7) of the OSI model and are specifically engineered to detect and block attacks targeting web applications, such as Cross-Site Scripting (XSS) and SQL injection, by analyzing HTTP/S traffic. They inspect requests for malicious patterns before they reach the application.

While WAFs can sometimes help detect suspicious login attempts, password cracking often involves brute-force attacks against authentication mechanisms, which are more broadly addressed by strong authentication, account lockout policies, and intrusion detection systems, not primarily WAFs.
