Which feature helps Palo Alto firewalls protect against DDoS attacks?

The DoS Protection profiles feature in Palo Alto firewalls is specifically designed to safeguard against Distributed Denial of Service (DDoS) attacks. These profiles allow administrators to define thresholds for various types of traffic, enabling the firewall to identify and mitigate abnormal traffic patterns associated with DDoS attacks. By setting these thresholds, the firewall can recognize when traffic exceeds expected norms, which is critical in stopping an overwhelming influx of traffic aimed at disrupting service availability.

In practical terms, DoS Protection profiles monitor traffic and can trigger responses such as rate limiting or blocking malicious traffic once the defined thresholds are crossed. This proactive approach helps maintain service continuity and security for legitimate users by reducing the attack's potential impact on network resources.

The other options, while essential for different security measures, do not specifically target the characteristics of DDoS attacks in the same way. Application Command Center and URL Filtering focus on visibility and web traffic management, and Advanced Threat Prevention primarily targets advanced malware and exploits rather than volumetric or protocol-based attacks typically associated with DDoS incidents. Thus, the DoS Protection profiles stand out as the dedicated feature for managing and mitigating DDoS threats in Palo Alto firewalls.
