Which firewall policies can utilize the Intrusion Prevention Service to block network attacks?

The correct answer is that all policies can utilize the Intrusion Prevention Service (IPS) to block network attacks. This is essential because the IPS feature is designed to provide comprehensive threat protection regardless of the specific type of traffic or policy in question.

Firewalls operate various types of policies—such as packet filter policies, proxy policies, and inbound/outbound policies—to manage network traffic. The IPS can monitor all these roles, ensuring that attacks can be identified and mitigated effectively, whether the traffic is coming from the outside (inbound), going out (outbound), or being filtered by a specific service (like HTTP/HTTPS). This allows for a unified defense against threats across the entire network, enhancing the overall security posture.

By employing IPS across all firewall policies, organizations can enjoy greater flexibility and robustness in their defense mechanisms, minimizing vulnerabilities across different types of traffic and interactions within their networks.
