The Cisco Firewall Services Module integrates which functionality?

The Cisco Firewall Services Module integrates a stateful-inspection firewall, which means it tracks the state of active connections and uses this information to determine which network packets to allow through the firewall. This stateful approach provides a more sophisticated level of security than basic packet filtering, as it can make decisions based on the established state of a connection.

By analyzing both the header information and the context of the data packets, the firewall can better defend against different types of network attacks, such as spoofing or denial of service. This functionality facilitates comprehensive monitoring and control of traffic, ensuring that only legitimate traffic is allowed, while unauthorized traffic is blocked.

The other choices focus on singular aspects of security features, but the integration of a stateful-inspection firewall provides a more holistic and effective approach to network security within the Cisco infrastructure.
