Enabling WAF

  • ► Navigate to the WAF settings.
  • ► Click on the drop-down list and select Enabled.
  • ► Navigate to the WAF hierarchy setting.
  • ↳ Once the WAF has been activated, the Use default value/Use inherited value is selected.

  • ► Check whether WAF rules should be used at the subdomain, domain, and tag levels.

    • If so, you do not need to make any changes.
    • If not, uncheck the Use default value/Use inherited value checkbox and check at least one of the three boxes: Domain), Subdomain, or Tag.

  • ► Navigate to the WAF default policy setting.

  • ► Click on the drop-down list and select one of the following values according to your needs:
  • ↳ Allow: If requests cannot be handled due to missing WAF rules, they are always allowed and the next security mechanism of the Myra App handles them.
  • ↳ Block: If requests cannot be handled due to missing WAF rules, they are always blocked.
  • ► Click on the Save button.
  • ➔ A message confirms that the setting has been successfully saved and the WAF is available for the selected domain or subdomain.

Repeat the step until WAF has been enabled for all required domains and subdomains.
