Testing security rules helps ensure that the network's security posture is robust and effective against potential threats. Security rules define how traffic is handled and controlled within the network. Testing these rules ensures that your security rules appropriately allow and deny traffic and access to applications and websites in compliance with your business needs and requirements.
We provide tools that let you simulate traffic flow based on a specific set of conditions defined in a security rule. By entering the necessary parameters such as source and destination IP addresses, ports, and applications, you can simulate the traffic flow and observe how your configuration would process it based on the configured security rules. This provides valuable insights into the effectiveness of the Security policy, which lets you verify if the security actions you intend, such as allowing or denying traffic, are correctly applied as per the security rules. You can also identify any misconfigurations or conflicts that might affect the policy's behavior.
Regularly testing security rules is essential for maintaining an efficient security posture. It enables you to adapt security rules to changing network requirements and evolving threat landscapes. By conducting thorough tests and fine-tuning security rules accordingly, you can ensure that your configuration operates optimally, providing reliable protection against a variety of cyberthreats.

Cloud Managed

Test the traffic policy matches of your configuration.
Updates to your Security rules are often time-sensitive and require you to act quickly. However, you want to ensure that any update you make to your Security policy rulebase meets your requirements and does not introduce errors or misconfigurations (such as changes that result in duplicate or conflicting rules).
Policy Analyzer in
Strata Cloud Manager
enables you to optimize time and resources when implementing a change request. Policy Analyzer not only analyzes and provides suggestions for possible consolidation or removal of specific rules to meet your intent but also checks for anomalies, such as Shadows, Redundancies, Generalizations, Correlations and Consolidations in your rulebase.
Use Policy Analyzer to analyze your Security rules both before and after you commit your changes.
  • Pre-Change Policy Analysis
    —Enables you to evaluate the impact of a new rule so you can compare that to your intent for that rule and ensure that it does not duplicate or conflict with existing rules before you commit to avoid security rule inflation. You can also run a Security Policy Anomaly Analysis to check for shadows, redundancies, generalizations, correlations and consolidations.
  • Post-Change Policy Analysis
    —Enables you to clean the existing rulebase by identifying shadows, redundancies, and other anomalies that have accumulated over time.
You can also use Policy Analyzer to add or optimize your Security policy rulebase.
  • Before adding a new rule
    —Check to see if new rules need to be added. Policy Analyzer recommends how best to change your existing Security policy rules to meet your requirements without adding another rule, if possible.
  • Streamline and optimize your existing rulebase
    —See where you can update your rules to minimize bloat and eliminate conflicts and also to ensure that traffic enforcement aligns with the intent of your Security policy rulebase.

PAN-OS & Panorama

Test the traffic policy matches of the running firewall configuration.
Panorama customers with the Cloud Connector Plugin can use Policy Analyzer to analyze Security rules both before and after committing changes to their configuration.
Policy Analyzer not only analyzes and provides suggestions for possible consolidation or removal of specific rules to meet your intent but also checks for anomalies, such as Shadows, Redundancies, Generalizations, Correlations and Consolidations in your rulebase.
  • Policy Analyzer requires the Cloud Connector Plugin 1.1.0 on your Panorama appliance.
  • Policy Analyzer requires Panorama to be updated to PAN-OS version 10.2.3 or a later version.
Both Panorama and PAN-OS customers can test and verify that security rules are allowing and denying the correct traffic by executing policy match tests for firewalls directly from the web interface.
  1. Select
    to perform a policy match or connectivity test.
  2. Enter the required information to perform the policy match test. In this example, we run a NAT policy match test.
    1. Select Test
      NAT Policy Match
    2. From
      —Select the zone traffic is originating from.
    3. To
      —Select the target zone of the traffic.
    4. Source
      —Enter the IP address from which traffic originated.
    5. Destination
      —Enter the IP address of the target device for the traffic.
    6. Destination Port
      —Enter the port used for the traffic. This port varies depending on the IP protocol used in the following step.
    7. Protocol
      —Enter the IP protocol used for the traffic.
    8. If necessary, enter any additional information relevant for your NAT security rule testing.
  3. Execute
    the NAT policy match test.
  4. Review the
    NAT Policy Match Result
    to see the policy rules that match the test criteria.
