# Guard Hooks
<a name="guard-hooks"></a>

To use an AWS CloudFormation Guard Hook in your account, you must *activate* the Hook for the account and Region where you want to use it. Activating a Hook makes it usable in stack operations in the account and Region where it's activated. 

When you activate a Guard Hook, CloudFormation creates an entry in your account's registry for the activated Hook as a private Hook. This allows you to set any configuration properties the Hook includes. Configuration properties define how the Hook is configured for a given AWS account and Region.
