Ensure WAF rule-group is not empty

Security & Compliance
No items found.
Description

The rule groups within AWS Web Application Firewall (WAF) are used to define a set of rules to protect your web applications from various types of attacks. An empty rule group means there are no rules defined, which could potentially leave the application vulnerable to attacks. Therefore, it is important to ensure that WAF rule groups are not empty.

Remediation

To ensure that the WAF rule-group is not empty, you can perform the following remediation steps:

  1. Log in to the AWS Management Console and navigate to the AWS WAF console.
  2. Click on the Rule groups tab on the left-hand side.
  3. Select the rule group for which you want to check if it is empty.
  4. Click on the rules tab under the selected rule group.
  5. If the rule group is empty, click on the Add rules button and select the rules that you want to add to the rule group.
  6. Once you have selected the rules, click on the Add rules button to add the selected rules to the rule group.
  7. Review and update the WAF web access control list to include the updated rule group.
  8. Verify that the rule group is no longer empty by checking the rules tab under the selected rule group.
  9. Repeat these steps for all the WAF rule groups that you have created to ensure that they are not empty.
