What is the primary function of FortiDDoS?

The primary function of FortiDDoS is to protect against distributed denial-of-service (DDoS) attacks. DDoS attacks aim to overwhelm a network, service, or application by flooding it with traffic from multiple sources, rendering it unavailable to legitimate users. FortiDDoS provides specific features designed to detect and mitigate these attacks by analyzing incoming traffic patterns, identifying malicious traffic, and automatically blocking or redirecting it to preserve the availability and performance of critical services.

Given the context of the other options, enhancing user authentication pertains to user access security, which is not the focus of FortiDDoS. Monitoring network traffic, while essential for overall network health and security, does not primarily address the challenges posed by DDoS attacks. Managing firewall policies relates to regulating traffic flow and access control but does not specifically address the unique threats posed by the volume and nature of DDoS traffic.
