# Security tip

For security reasons, it is advisable to configure enrollment agent restrictions for a CA to allow only the newly created Enrollment Agent User permissions to enroll certificates on behalf of the users. To do so, follow the steps below.

1. Open the Certification Authority snap-in, right-click the name of the CA, and then click **Properties**.
2. Click the **Enrollment Agents** tab, click **Restrict enrollment agents**, and click **OK** on the message that appears.
3. Under **Enrollment agents**, click **Add**, type the name of the Enrollment agent user created in the previous steps and then click **OK**. Click **Everyone**, and then click **Remove**.
4. Under **Certificate Templates**, click **Add**, select the templates that were created (Prls Enrollment Agent and Prls Smartcard Logon) and then click **OK**. When you have finished adding the names of certificate templates, click **\<All>**, and then click **Remove**.
5. Under **Permissions**, click **Add**, type the names or groups, which are the users or group expected to login to the RAS environment using SAML, and then click **OK**. Click **Everyone**, and then click **Remove**.
6. If you want to block the enrollment agent from managing certificates for other users, computers, or groups, under **Permissions**, select this user, computer, or group, and then click **Deny**.
7. When you are finished configuring enrollment agent restrictions, click **OK** or **Apply**.

**Note:** The user or group that you applied enrollment agent restrictions to must have a valid enrollment agent certificate for the CA before they can act as an enrollment agent, whether restricted enrollment agent permissions have or have not been configured.
