Cloud NGFW for AWS Rule Usage
Use Panorama to manage rules on your Cloud NGFW resource to track and monitor rule usage
for operations and troubleshooting tasks. On your Panorama console, you can view the
rule usage at cloud device group to determine if all, some, or none of the Cloud NGFW
resources have traffic matches.
On Panorama, you can view the rule usage details for managed firewalls that have policy
rule hit count enabled (default), and for which you have defined and pushed policy rules
using device groups. Panorama cannot retrieve rule usage details for policy rules
configured locally on the firewall so you must log in to the firewall to view rule usage
information for locally configured rules. For more information, see Monitor Policy Rule Usage.
Rule Usage - Rule Hit and Policy Optimizer
System Requirements
The following are the minimum system requirements to monitor your security policy
rule usage:
- Panorama (PAN-OS) version 10.2.8 and above
- AWS Plugin version 5.2.0 and above
- Cloud Services Plugin version 5.0.0 and above
- Cloud Connector Plugin version 2.0.1 and above
View the Rule Hit Count for a Cloud Device Group
In the Panorama console, after you associate a cloud device group to a
Cloud NGFW resource and configure policies for the cloud device group, perform
the following steps to view the rule hit count for a cloud device group in
Panorama:
The NGFW firewall resources report your rulehit data for every 2
minutes to the Cloud NGFW service, and then the cloud NGFW service will have
a latency of maximum 2 minute to poll data from firewall resources. This
will create a maximum of 4 minute latency in rule hit count data display on
the Panorama console.
- SelectPolicies.
- In theDevice Groupsection, use the drop-down to select the Cloud Device Group.
- Select a Rule, and clickRule Usage.You can monitor the rule usage status of your Pre, Post, and Default rules of Security, Decryption, and Application-override policy types.
You can now see theHit Countof the selected rule.
In the Panorama console, the rule hit count gets refreshed for every 4-minute interval, by default.ClickReset Rule Hit Counterto refresh the hit count of the selected rule.ClickPDF/CSVto export the Rule usage details of a selected rule as a CSV or PDF file.
Rule Usage - App Seen and Policy Optimizer
You can view all your applications seen and allowed on the firewall that
match with your security policy rule. The number in
Apps Seen
column
indicates how many applications were seen on the rule.- In the Panorama console, go to thePoliciestab.
- In theDevice Groupsection, use the drop-down to select the Cloud Device Group.
- Select a Rule, and clickApps seen.
You can now see the applications configured and displayed on your security policy rule.
For more information on Apps on Rule, Apps seen, and App seen actions, see
Applications and Usage.
In the
Policy Optimizer
section, you can also view the rule hit count for all
your configured cloud device groups on Panorama. Policy Optimizer provides a simple
workflow to migrate your legacy Security policy rulebase to an App-ID based
rulebase, which improves your security by reducing the attack surface and gaining
visibility into applications so you can safely enable them. For more information,
see Security Policy Rule Optimization and
Applications and Usage.
