How to manage secrets?

What is the secret of effective secrets management? Why is it critical to safeguard sensitive data and maintain the security of applications? Explore the significance of secrets management and best practices to protect your valuable information.

Secrets refer to confidential or sensitive data that must be protected from unauthorized access: authentication credentials, encryption keys, certificates, and private keys. But what exactly does secrets management entail, and why is it vital for DevOps?

The Evolution from Hardcoding to Advanced Solutions

The Downside of Hardcoding Secrets

Hardcoding secrets directly into the source code is a practice fraught with risks. While it may seem convenient, it exposes sensitive information like API keys and passwords to unauthorized access, compromising the security of applications and infrastructure.

Transition to Config Files and Environment Variables

The first step towards better secrets management is to move hardcoded configurations to dedicated config files. This approach allows for using environment variables to overwrite default values, making storing these files in a repository safer.

Storing Secrets in Config Repositories

Keeping secrets in a separate config repository offers better access control. However, this method still involves storing secrets in plaintext, making it only moderately secure.

Encrypting Secrets in Config Repositories

Using “sealed secrets” with asymmetric keys offers a more secure way to manage secrets. This method encrypts the secrets, making them both secure and manageable through the config repository.

Utilizing Dedicated Services for Secrets Management

Dedicated services like Azure Key Vault, AWS Secrets Manager, and HashiCorp Vault can be employed for enhanced security. These services offer robust features such as monitoring and partial support for the automatic rotation of secrets.
