## Step 1: Completing the prerequisites
<a name="complete-prereq"></a>

There are several mandatory steps to prepare your account for Amazon Firewall Manager. Those steps are described in [Amazon Firewall Manager prerequisites](fms-prereq.md). Complete all of the prerequisites before proceeding to [Step 2: Creating and applying an Amazon WAF policy](#get-started-fms-create-security-policy).

## Step 2: Creating and applying an Amazon WAF policy
<a name="get-started-fms-create-security-policy"></a>

A Firewall Manager Amazon WAF policy contains the rule groups that you want to apply to your resources. Firewall Manager creates a Firewall Manager web ACL in each account where you apply the policy. The individual account managers can add rules and rule groups to the resulting web ACL, in addition to the rule groups that you define here. For information about Firewall Manager Amazon WAF policies, see [Using Amazon WAF policies with Firewall Manager](waf-policies.md).

**To create a Firewall Manager Amazon WAF policy (console)**

Sign in to the Amazon Web Services Management Console using your Firewall Manager administrator account, and then open the Firewall Manager console at [https://console.aws.amazon.com/wafv2/fmsv2](https://console.aws.amazon.com/wafv2/fmsv2). For information about setting up a Firewall Manager administrator account, see [Amazon Firewall Manager prerequisites](fms-prereq.md).

1. In the navigation pane, choose **Security policies**.

1. Choose **Create policy**.

1. For **Policy type**, choose **Amazon WAF**. 

1. For **Region**, choose an Amazon Web Services Region. To protect Amazon CloudFront distributions, choose **Global**.

   To protect resources in multiple Regions (other than CloudFront distributions), you must create separate Firewall Manager policies for each Region.

1. Choose **Next**.

1. For **Policy name**, enter a descriptive name. Firewall Manager includes the policy name in the names of the web ACLs that it manages. The web ACL names have `FMManagedWebACLV2-` followed by the policy name that you enter here, `-`, and the web ACL creation timestamp, in UTC milliseconds. For example, `FMManagedWebACLV2-MyWAFPolicyName-1621880374078`.
**Important**  
Web ACL names can't change after creation. If you update your policy's name, Firewall Manager won't update the associated web ACL name. To have Firewall Manager create a web ACL with a different name, you must create a new policy.

1. Under **Policy rules**, for **First rule groups**, choose **Add rule groups**. Expand the **Amazon managed rule groups**. For **Core rule set**, toggle **Add to web ACL**. For **Amazon known bad inputs**, toggle **Add to web ACL**. Choose **Add rules**.

   For **Last rule groups**, choose **Add rule groups**. Expand the **Amazon managed rule groups** and for the **Amazon IP reputation list**, toggle **Add to web ACL**. Choose **Add rules**.

   Under **First rule groups**, select **Core rule set** and choose **Move down**. Amazon WAF evaluates web requests against the **Amazon known bad inputs** rule group before it evaluates against the **Core rule set**. 

   You can also create your own Amazon WAF rule groups if you want, using the Amazon WAF console. Any rule groups that you create show up under **Your rule groups** in the **Describe policy : Add rule groups page**.

   The first and last Amazon WAF rule groups that you manage through Firewall Manager have names that begin with `PREFMManaged-` or `POSTFMManaged-`, respectively, followed by the Firewall Manager policy name, and the rule group creation timestamp, in UTC milliseconds. For example, `PREFMManaged-MyWAFPolicyName-1621880555123`.

1. Leave the default action for the web ACL at **Allow**. 

1. Leave the **Policy action** at the default, to not automatically remediate noncompliant resources. You can change the option later. 

1. Choose **Next**.

1. For **Policy scope**, you provide the settings for the accounts, resource types, and tagging that identify the resources you want to apply the policy to. For this tutorial, leave the **Amazon Web Services accounts** and **Resources** settings, and choose one or more resource types.

1. For **Resources**, you can narrow the scope of the policy using tagging, by either including or excluding resources with the tags that you specify. You can use inclusion or exclusion, and not both. For more information about tags to define policy scope, see [Using the Amazon Firewall Manager policy scope](policy-scope.md).

   Resource tags can only have non-null values. If you omit the value for a tag, Firewall Manager saves the tag with an empty string value: "". Resource tags only match with tags that have the same key and the same value. 

1. Choose **Next**.

1. For **Policy tags**, add any identifying tags that you want to add to the Firewall Manager policy resource. For more information about tags, see [Working with Tag Editor](https://docs.amazonaws.cn/awsconsolehelpdocs/latest/gsg/tag-editor.html).

1. Choose **Next**.

1. Review the new policy settings and return to any pages where you need to any adjustments. 

   Check to be sure that **Policy actions** is set to **Identify resources that don’t comply with the policy rules, but don’t auto remediate.** This allows you to review the changes that your policy would make before you enable them. 

1. When you are satisfied with the policy, choose **Create policy**.

   In the **Amazon Firewall Manager policies** pane, your policy should be listed. It will probably indicate **Pending** under the accounts headings and it will indicate the status of the **Automatic remediation** setting. The creation of a policy can take several minutes. After the **Pending** status is replaced with account counts, you can choose the policy name to explore the compliance status of the accounts and resources. For information, see [Viewing compliance information for an Amazon Firewall Manager policy](fms-compliance.md)

## Step 3: Cleaning Up
<a name="clean-up"></a>

To avoid extraneous charges, delete any unnecessary policies and resources. 

**To delete a policy (console)**

1. On the **Amazon Firewall Manager policies** page, choose the radio button next to the policy name, and then choose **Delete**. 

1. In the **Delete** confirmation box, select **Delete all policy resources**, and then choose **Delete** again.

   Amazon WAF removes the policy and any associated resources, like web ACLs, that it created in your account. The changes might take a few minutes to propagate to all accounts.
