What is the purpose of the external dynamic list (EDL) in Cortex XSOAR?

The external dynamic list (EDL) in Cortex XSOAR serves the purpose of dynamically updating firewall rules by integrating real-time threat intelligence data. This allows security teams to respond swiftly to emerging threats by automatically adjusting firewall configurations based on the latest intelligence, which helps improve the overall security posture. EDLs enable organizations to proactively block or allow traffic based on ongoing threat analysis, ensuring that their defenses are always up to date with current threat landscapes.

In this context, the other options do not accurately reflect the primary function of an EDL. While a dynamic updating of firewall rules is crucial for maintaining security, the roles of blocking permanent threats, evaluating alert priorities, and directly integrating third-party intelligence are typically managed through different mechanisms or tools within the broader security framework.
