![]() ![]() This negates the need for your application developers to hard-code any secret or credentials within your applications, instead, when a secret value is required, an API call to AWS Secrets Manager is triggered which will then return the value. AWS Secrets Manager holds, protects and contains sensitive secret information for you, allowing other services and applications to call for the secret via a simple API call. So let’s now take a quick look at AWS Secrets Manager. When setting up your parameter, you can configure it as as a single string of any value, a StringList, which would contain multiple string separated by commas, or a SecureString which is backed by the AWS Key Management Service to provide a means of encrypting your parameter value. Other examples of parameters may include environment variables, database strings, plain text data strings, and AMI-IDs, basically anything that could be a parameter. Additional security features can be added to these parameters, for example using encryption to hide sensitive data, such as passwords and other secrets. The Parameter Stores main function is to provide you with a means of centrally storing parameters to be used within your environment allowing your applications to retrieve the parameter value via simple API calls as and when required. So the Parameter store is a feature that is a part of the AWS Systems Manager service, also known as SSM, and this service gives you centralized visibility and control allowing for operational, application, change and node management across your AWS infrastructure.ĪWS Systems Manager Parameter Store feature sits under the Application management element of SSM. Ok, so let’s start by establishing what both the Parameter Store and Secrets Manager are used for before we compare them against each other. Having a central store of all of our secrets makes it easy for applications to retrieve the value of a secret. ![]() This minimises administrative burden when it comes to rotation, in addition to enhancing the security posture of our AWS accounts. Firstly, why do we have services that are dedicated to centrally storing parameters and secrets for us? They allow us to implement security best practices preventing us from having to hardcode any credentials within custom applications. ![]()
