What feature of FortiGate can help prevent DDoS attacks?

The feature of FortiGate that specifically addresses the prevention of Distributed Denial of Service (DDoS) attacks is the DoS protection features. These features are designed to detect and mitigate various types of denial of service (DoS) attacks, including DDoS, by monitoring traffic patterns and applying thresholds that can trigger protective measures.

DoS protection incorporates techniques such as flow and session limits, serving to restrict the number of allowed connections or requests to resources from a single source or to a particular service. By deploying these measures, FortiGate can help ensure that legitimate traffic is still able to access services while blocking potentially malicious traffic designed to overwhelm system resources.

The other features, such as SSL inspection, Web application firewall, and content filtering, serve important roles in overall network security but do not specifically focus on mitigating DDoS attacks. SSL inspection is used primarily for analyzing encrypted traffic to detect threats, a Web application firewall protects web applications from various types of attacks but does not inherently focus on DDoS mitigation, and content filtering is aimed at controlling access to content rather than managing large volumes of attack traffic.
