Regulatory Requirements for Credential Storage

Regulated industries face specific requirements for how credentials, secrets, and encryption keys are stored, accessed, and audited.

SOC 2: Requires documented access controls, credential rotation policies, and audit trails for secret access. Credential sharing must be auditable.

HIPAA: Protected Health Information (PHI) access must be logged, time-limited, and role-based. Encryption keys for PHI must be managed with documented procedures.

PCI-DSS: Payment card data encryption keys must be stored in the fewest possible locations, split knowledge and dual control principles applied, and keys rotated annually at minimum.

GDPR: Encryption keys for personal data must be documented, access controlled, and handled according to data protection principles.

Compliant Credential Storage Architecture

1. Centralized Secret Management Use a dedicated secrets management service: • AWS Secrets Manager or AWS Systems Manager Parameter Store • HashiCorp Vault • Azure Key Vault • Google Cloud Secret Manager

These services provide encryption at rest, access controls, audit logging, and automated rotation — all requirements across most regulatory frameworks.

2. Access Control • Principle of least privilege — each service and user gets only the credentials they need • Role-based access control (RBAC) for credential access • Time-limited access for sensitive credentials • Regular access reviews (quarterly at minimum)

3. Audit Trail • Log every credential access event • Include who accessed what, when, and from where • Retain logs according to your regulatory requirements • Make logs tamper-resistant (write-once storage, SIEM integration)

Emergency Access in Regulated Environments

Even in regulated environments, emergency access must be planned:

Break-Glass Procedures: Documented, audited procedures for emergency credential access that bypass normal access controls. Must include post-incident review and re-securing.

Continuity for compliance owners: If a compliance officer or security lead becomes unavailable, authorised backups need current documentation and provider access. A scoped ZeroLatch delivery can support the longer-term plan but does not ensure continuity or satisfy an audit by itself.

Documentation: All emergency access events must be documented, reviewed, and explained during audits. Ensure your dead man's switch service provides activity records that your team reviews against its regulatory requirements.

Proper emergency access planning actually strengthens your compliance posture — it shows auditors that you've thought through contingencies, not just baseline operations.
