About Access Control Policies
The simplest access control policy handles all traffic using its default action . You can set this default action to block or trust all traffic without further inspection, or to inspect traffic for intrusions.
Note that only ASA FirePOWER modules deployed inline can affect the flow of traffic. Applying an access control policy configured to block or alter traffic to passively deployed devices can have unexpected results. In some cases, the system prevents you from applying inline configurations to passively deployed ASA FirePOWER modules.
A more complex access control policy can block traffic based on Security Intelligence data, as well as use access control rules to exert granular control over network traffic logging and handling. These rules can be simple or complex, matching and inspecting traffic using multiple criteria. Advanced access control policy options control decryption, preprocessing, performance, and other general preferences.
After you create a basic access control policy, see the following chapters for more information on tailoring it to your deployment:
Blocking Traffic Using Security Intelligence IP Address Reputation explains how to immediately block connections based on the latest reputation intelligence.
About Network Analysis and Intrusion Policies explains how network analysis and intrusion policies preprocess and examine packets, as part of the system’s intrusion detection and prevention feature.
Tuning Traffic Flow Using Access Control Rules explains how access control rules provide a granular method of handling network traffic across multiple ASA FirePOWER modules.
Controlling Traffic Using Intrusion and File Policies explains how intrusion and file policies provide the last line of defense before traffic is allowed to its destination, by detecting and optionally blocking intrusions, prohibited files, and malware.
