Firewall Manager policy issues.

AWS Firewall Manager is a security management service that makes it easier to centrally configure and manage AWS WAF rules and AWS Shield Advanced protections across multiple accounts and resources. If you're experiencing issues with Firewall Manager policies, here are some common causes and steps to address them:

1. Invalid Policy Configuration:
   • Cause: Incorrect settings in the Firewall Manager policy can lead to issues with rule enforcement or resource association.
   • Solution: Review and update the policy settings to ensure they match your security requirements.
2. Policy Not Applied to All Resources:
   • Cause: The policy may not be associated with all the intended resources.
   • Solution: Verify that the policy is associated with the correct resources and accounts. You can check the policy association status in the Firewall Manager console.
3. Incorrect Rule Evaluation Order:
   • Cause: The order of rules in a policy can affect which rules are evaluated first.
   • Solution: Review the rule order in the policy and adjust it if necessary to ensure that rules are evaluated in the correct sequence.
4. Policy Violations:
   • Cause: If a policy is set to be in "audit mode," it may not actively block requests but instead generate logs for review.
   • Solution: Check the policy mode (audit or enforced) and adjust it as needed.
5. Invalid Rule Configuration:
   • Cause: Incorrect settings or conditions in individual rules can lead to unexpected behavior.
   • Solution: Review and update the rule settings to ensure they accurately represent your security requirements.
6. Insufficient Permissions:
   • Cause: The IAM role associated with Firewall Manager may not have the necessary permissions to apply policies to resources.
   • Solution: Review and update the IAM policies associated with the Firewall Manager service role to ensure it has the required permissions.
7. Check for AWS Service Issues:
   • Solution: Occasionally, AWS services may experience outages or issues. Check the AWS Service Health Dashboard for any reported problems.
8. Review Firewall Manager Logs:
   • Solution: Review the Firewall Manager logs for detailed information about policy enforcement and any issues encountered.
9. Contact AWS Support:
   • Solution: If none of the above steps resolve the issue, consider reaching out to AWS Support for further assistance.

Remember to document any error messages or specific details about the policy issues, as this information can be helpful in diagnosing and resolving the problem.
