Adding a managed rule group to a web ACL through the console

This section explains how to add a managed rule group to a web ACL through the console. This guidance applies to all AWS Managed Rules rule groups and to the AWS Marketplace rule groups that you're subscribed to.

Production traffic risk

Before you deploy changes in your web ACL for production traffic, test and tune them in a staging or testing environment until you are comfortable with the potential impact to your traffic. Then test and tune your updated rules in count mode with your production traffic before enabling them. For guidance, see Testing and tuning your AWS WAF protections.

Note

Using more than 1,500 WCUs in a web ACL incurs costs beyond the basic web ACL price. For more information, see Understanding web ACL capacity units (WCUs) in AWS WAF and AWS WAF Pricing.

To add a managed rule group to a web ACL through the console

  1. Sign in to the AWS Management Console and open the AWS WAF console at https://console.aws.amazon.com/wafv2/.

  2. Choose Web ACLs in the navigation pane.

  3. In the Web ACLs page, from the list of web ACLs, select the one that you want to add the rule group to. This takes you to the page for the single web ACL.

  4. In your web ACL's page, choose the Rules tab.

  5. In the Rules pane, choose Add rules, then choose Add managed rule groups.

  6. In the Add managed rule groups page, expand the selection for your rule group vendor, to see the list of available rule groups.

  7. For each rule group that you want to add, choose Add to web ACL. If you want to change the web ACL's configuration for the rule group, choose Edit, make your changes, and then choose Save rule. For information about the options, see the versioning guidance at Using versioned managed rule groups in AWS WAF and the guidance for using a managed rule group in a web ACL at Using managed rule group statements in AWS WAF.

  8. At the bottom of the Add managed rule groups page, choose Add rules.

  9. In the Set rule priority page, adjust the order that the rules run as needed, then choose Save. For more information, see Setting rule priority in a web ACL.

In your web ACL's page, the managed rule groups that you've added are listed under the Rules tab.

Test and tune any changes to your AWS WAF protections before you use them for production traffic. For information, see Testing and tuning your AWS WAF protections.

Temporary inconsistencies during updates

When you create or change a web ACL or other AWS WAF resources, the changes take a small amount of time to propagate to all areas where the resources are stored. The propagation time can be from a few seconds to a number of minutes.

The following are examples of the temporary inconsistencies that you might notice during change propagation:

  • After you create a web ACL, if you try to associate it with a resource, you might get an exception indicating that the web ACL is unavailable.

  • After you add a rule group to a web ACL, the new rule group rules might be in effect in one area where the web ACL is used and not in another.

  • After you change a rule action setting, you might see the old action in some places and the new action in others.

  • After you add an IP address to an IP set that is in use in a blocking rule, the new address might be blocked in one area while still allowed in another.
