What security feature is used in Sophos Firewall to protect from DDoS attacks?

In the context of Sophos Firewall and its security features, the correct choice revolves around the specific measures implemented to safeguard against Distributed Denial of Service (DDoS) attacks. Flood protection and SYN flood protection are designed to identify and mitigate abnormal traffic patterns that typically characterize DDoS attacks.

Flood protection focuses on monitoring and controlling excessive traffic flows, while SYN flood protection specifically addresses the exploitation of the TCP handshake process, where an attacker sends an overwhelming number of SYN requests to a target, creating a situation where the server cannot handle legitimate requests. By utilizing these protective mechanisms, Sophos Firewall can effectively limit the impact of DDoS attacks, helping to ensure that legitimate users maintain access to network resources despite the malicious activity.

Other security features, such as URL filtering, content inspection, and application control, serve important security functions but are not specifically tailored for the immediate impacts of DDoS attacks. URL filtering primarily manages access to web resources, content inspection deals with inspecting data for threats, and application control governs the use of applications on the network. While these features all contribute to an organization's overall security posture, they do not directly mitigate DDoS attack traffic in the same specialized way as flood and SYN flood protection do.
