Secrets Managers

Author: Michael J. Leaver (2BrightSparks Pte. Ltd.) and ChatGPT (OpenAI)

A secrets manager is like a super-safe vault for digital keys and passwords that sensitive computer programs and apps use to unlock important information. It keeps these secrets protected from hackers, making sure that only the right programs and people can access them. This helps keep our digital world secure by making sure that only trusted sources can use these secret codes, while also making it easier to change these codes regularly to stay one step ahead of any potential threats.

For example, in the context of a backup application, a secrets manager (e.g. AWS Secrets Manager) is integrated to securely manage important credentials, such as cloud storage API keys. Instead of embedding these keys directly within the application's code, the backup app retrieves them from the secrets manager. Access to the secrets manager is restricted exclusively to the backup application. Automated rotation of the API keys is handled by the secrets manager, ensuring that keys are regularly updated for heightened security. When the backup application requires access to cloud storage, it fetches the current API key from the secrets manager. This approach bolsters security by preventing direct exposure of sensitive credentials within the code, while also simplifying the management of critical secrets for seamless backup operations.

There are numerous secrets managers available, e.g. AWS Secrets Manager, Azure Key Vault, Google Cloud Secret Manager and HashiCorp Vault.

Secrets Managers

Secrets Managers are specialized tools designed to securely manage and store sensitive information in modern IT environments. These tools are particularly useful for storing and distributing sensitive data, such as API keys, passwords, encryption keys, and other credentials, that are needed by applications, services, and users. Here's a high-level description of how Secrets Managers work:

  • Secure Storage: Secrets Managers provide a secure repository for storing sensitive information. This information is encrypted at rest and in transit to ensure that even if unauthorized access occurs, the data remains protected.
