What Is Secrets Management?
Secrets management addresses a fundamental security challenge: applications and infrastructure need credentials (database passwords, API keys, TLS certificates, encryption keys) to function, but hardcoding these secrets in source code, config files, or environment variables creates serious risk.
A secrets management solution provides a centralized, encrypted vault for storing secrets, with fine-grained access control and automatic rotation.
Why Secrets Management Matters
Common secrets management failures include:
- Hardcoded credentials in source code pushed to Git repositories
- Shared service accounts with passwords that never rotate
- Secrets sprawl across config files, CI/CD pipelines, and environment variables
- No audit trail of which applications or users accessed which secrets
Any of these can lead to a breach. Leaked cloud credentials, in particular, are one of the most common causes of cloud security incidents.
