Explanation
Each rule also has an action, which determines whether you monitor, trust, block, or allow matching traffic.
Note: With action "trust", Firepower does not do any more inspection on the traffic. There will be no intrusion protection and also no file-policy on this traffic.

Explanation
Micro-segmentation secures applications by expressly allowing particular application traffic and, by default, denying all other traffic. Micro-segmentation is the foundation for implementing a zero-trust security model for application workloads in the data center and cloud.
Cisco Tetration is an application workload security platform designed to secure your compute instances across any infrastructure and any cloud. To achieve this, it uses behavior and attribute-driven microsegmentation policy generation and enforcement. It enables trusted access through automated, exhaustive context from various systems to automatically adapt security policies.
To generate accurate microsegmentation policy, Cisco Tetration performs application dependency mapping to discover the relationships between different application tiers and infrastructure services. In addition, the platform supports "what-if" policy analysis using real-time data or historical data to assist in the validation and risk assessment of policy application pre-enforcement to ensure ongoing application availability. The normalized microsegmentation policy can be enforced through the application workload itself for a consistent approach to workload microsegmentation across any environment, including virtualized, bare-metal, and container workloads running in any public cloud or any data center. Once the microsegmentation policy is enforced, Cisco Tetration continues to monitor for compliance deviations, ensuring the segmentation policy is up to date as the application behavior change.
