# Protect the Configuration with AWS Key Management Service Amazon AWS Key Management Service can be utilized on an EC2 instance hosting Keeper Commander in order to protect and store the configuration data. The AWS Key Management Service protected storage resource URL format is as follows: ``` aws-kms:/// ``` **Example**: `aws-kms://us-east-1/12345678-abcd-1234-dcba-123456789012` `aws-kms://eu-west-1/alias/key` The secret name should contain URL-safe characters Keeper Commander requires the "key users policy" to be granted to AWS user or role. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
