# Prevent AWS Secrets Manager replication
<a name="replicate-secrets-permissions"></a>

Because secrets can be replicated using [https://docs.aws.amazon.com/secretsmanager/latest/apireference/API_ReplicateSecretToRegions.html](https://docs.aws.amazon.com/secretsmanager/latest/apireference/API_ReplicateSecretToRegions.html) or when they are created using [https://docs.aws.amazon.com/secretsmanager/latest/apireference/API_CreateSecret.html](https://docs.aws.amazon.com/secretsmanager/latest/apireference/API_CreateSecret.html), if you want to prevent users from replicating secrets, we recommend you prevent actions that contain the `AddReplicaRegions` parameter. You can use a `Condition` statement in your permission policies to only allow actions that don't add replica regions. See the following policy examples for Condition statements you can use.

**Example Prevent replication permission**  
The following policy example shows how to allow all actions that don't add replica regions. This prevents users from replicating secrets through both `ReplicateSecretToRegions` and `CreateSecret`.

{
  "Version":"2012-10-17",		 	 	 
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "secretsmanager:*",
      "Resource": "*",
      "Condition": {
        "Null": {
          "secretsmanager:AddReplicaRegions": "true"
        }
      }
    }
  ]
}
```

**Example Allow replication permission only to specific Regions**  
The following policy shows how to allow all of the following:  
+ Create secrets without replication
+ Create secrets with replication to Regions only in United States and Canada
+ Replicate secrets to Regions only in United States and Canada
