Your customer has a primary key that is fine. How would you find and manage secrets in the database? The key is to treat secrets as first‑class data and apply a layered security strategy. First, classify which columns or rows contain secrets (e.g., SSN, API keys, PII). Then decide on encryption: at rest, use Transparent Data Encryption (TDE) for the whole database, and column‑level encryption for highly sensitive data. For secrets that need to be accessed by applications, store them in a dedicated secrets store (e.g., AWS Secrets Manager, HashiCorp Vault) and reference them via environment variables or a secure lookup service. Use key management services (KMS) to rotate encryption keys regularly. Audit access by enabling database audit logs and monitoring for unusual queries. Finally, enforce least‑privilege access: grant users only the permissions they need, and use row‑level security or views to hide secrets from unauthorized users. By combining encryption, secure storage, key rotation, and strict access controls, you can effectively find, protect, and manage secrets in the database while keeping the primary key intact.
