secretmanagement

Secret management refers to the processes and tools used to store, manage, and access sensitive information such as passwords, API keys, tokens, encryption keys, and certificates throughout their lifecycle. The goal is to reduce risk by protecting confidentiality, integrity, and availability of secrets across applications, infrastructure, and deployment pipelines.

A typical secret management solution provides secure storage (encrypted at rest), access control (authentication and authorization), secret rotation and revocation, auditing, versioning, and retrieval mechanisms. Secrets are usually stored in a centralized vault and accessed via controlled APIs or SDKs, often with short-lived or dynamic secrets.

Best practices include avoiding hardcoding secrets, enabling least-privilege access, automating rotation, using dynamic secrets when possible, enforcing strict authentication (such as MFA and short-lived tokens), maintaining comprehensive access logs, and implementing secure provisioning and de-provisioning. It is common to integrate secret management with CI/CD pipelines and platform components; in Kubernetes, external secret management is typically preferred over relying on Kubernetes Secrets alone.

Common tools and services include HashiCorp Vault, AWS Secrets Manager, Azure Key Vault, Google Secret Manager, CyberArk Conjur, and Doppler. Standards and concepts frequently involved are envelope encryption with key management services (KMS) and PKI for certificates. Access typically relies on API-driven retrieval, accompanied by audit trails and compliance reporting.

Challenges encompass secret sprawl, misconfiguration, leakage via logs, secure deletion, and potential vendor lock-in. Governance considerations involve defining roles, access policies, retention requirements, and incident response procedures. The field evolves with cloud-native architectures and zero-trust security models.
