+Whether you're about to enable or have already deployed attack surface reduction rules for your organization, see the information in this article. By using the tips and best practices in this article, you can employ attack surface reduction rules successfully and avoid potential issues.
+
+## Use a phased approach
+

This approach enables you to see how attack surface reduction rules work in your environment and gives you flexibility in applying exclusions. You can do this with dynamic membership rules.
+
+<!--Siddarth, we need to find the info about how to set up dynamic membership rules and add a procedure here.-->
