Secrets Management
Secrets management is the practice of securely storing, distributing, rotating, and auditing sensitive credentials — such as API keys, passwords, and certificates — so they are never hard-coded or exposed in plain text.
Definition
Secrets management is the practice of securely storing, distributing, rotating, and auditing sensitive credentials — such as API keys, passwords, and certificates — so they are never hard-coded or exposed in plain text.
Overview
Applications and infrastructure rely on many types of secrets: database passwords, third-party API keys, TLS private keys, and cloud service credentials. Storing these directly in source code, configuration files, or environment variables checked into version control is a common but serious mistake, since it exposes secrets to anyone with repository access and makes rotation difficult. Dedicated secrets management tools instead store secrets in an encrypted vault, grant access dynamically based on Identity and Access Management (IAM) policies, and support automatic rotation so credentials don't remain valid indefinitely. Widely used tools include HashiCorp Vault, AWS Secrets Manager, Azure Key Vault, and Google Secret Manager, all of which integrate with application runtimes so secrets are fetched at deploy or run time rather than baked into artifacts. Good secrets management practice also includes short-lived, dynamically generated credentials wherever possible (rather than static long-lived ones), detailed access auditing, and automated scanning of code repositories to catch accidentally committed secrets before they reach production. Secrets management underpins Encryption at Rest key handling and Privileged Access Management (PAM) credential vaulting, and is a core practice covered in DevSecOps & Security Automation.
Key Concepts
- Stores secrets in an encrypted vault rather than in code or config files
- Grants access dynamically based on IAM policies rather than static sharing
- Supports automatic credential rotation to limit exposure over time
- Prefers short-lived, dynamically generated credentials over static ones
- Includes auditing of who accessed which secret and when
- Integrates with CI/CD pipelines to avoid baking secrets into build artifacts
