Data Encryption Verification Checklist [FREE PDF]

Data encryption is a fundamental security control mandated by multiple regulatory frameworks, including GDPR Article 32(1)(a), HIPAA Security Rule 45 CFR §164.312(a)(2)(iv) and §164.312(e)(2)(ii), and PCI DSS v4.0 Requirements 3.5 and 4.2. Organizations must verify that encryption is applied to data at rest, data in transit, and in backup storage, using approved algorithms and properly managed cryptographic keys. This checklist provides a systematic approach to verifying encryption implementatio

  • Industry: Cloud Services
  • Frequency: Quarterly
  • Estimated Time: 45-60 minutes
  • Role: CISO
  • Total Items: 36
  • Compliance: GDPR Article 32(1)(a) - Encryption of Personal Data, HIPAA Security Rule 45 CFR §164.312(a)(2)(iv) & §164.312(e)(2)(ii), PCI DSS v4.0 Requirement 3.5 (Data at Rest) & 4.2 (Data in Transit), ISO 27001:2022 Annex A.10.1 Cryptographic Controls, NIST CSF PR.DS-1 & PR.DS-2 Data-at-Rest and Data-in-Transit Protection

Encryption Policy & Governance

Confirm that a formal cryptographic policy exists, is current, and governs encryption standards across the organization.

  • Does the organization have a documented Cryptographic Controls Policy that specifies approved algorithms and key lengths?
  • Has the Cryptographic Controls Policy been reviewed and approved within the past 12 months?
  • Does the policy explicitly prohibit the use of deprecated cryptographic algorithms (e.g., DES, 3DES, RC4, MD5, SHA-1)?
  • Are encryption requirements mapped to data classification levels in the policy?
  • Is responsibility for cryptographic control oversight assigned to a named role (e.g., CISO, Encryption Officer)?

Data at Rest Encryption

Verify that all regulated data stored on servers, databases, endpoints, and cloud storage is encrypted using approved algorithms.

  • Are all databases containing regulated data (PII, PHI, PAN) encrypted at rest using AES-256 or equivalent?
  • Are file system or full-disk encryption controls enabled on all endpoints and servers that store regulated data?
  • Are cloud storage buckets or blob storage containers holding regulated data configured with server-side encryption?
  • Has encryption coverage of data-at-rest been verified through a technical control scan or configuration review within the past quarter?
  • Are database encryption configurations documented with algorithm, key length, and implementation date?

Data in Transit Encryption

Confirm that all data transmitted over networks, internal and external, is protected by approved transport encryption protocols.

  • Is TLS 1.2 or higher enforced for all external-facing web services, APIs, and customer-facing applications?
  • Is TLS 1.2 or higher enforced for all internal service-to-service and microservice communications?
  • Are SSL 3.0, TLS 1.0, and TLS 1.1 explicitly disabled on all servers and load balancers?
  • Are TLS certificate expiry dates monitored with automated alerts set to trigger at least 30 days before expiration?
  • Are email communications containing regulated data sent using S/MIME, PGP, or a secure email gateway with TLS enforcement?
  • Are VPN or encrypted tunnels used for all remote administrative access to production systems?

Cryptographic Key Management

Evaluate the security and maturity of cryptographic key generation, storage, rotation, and revocation processes.

  • Are cryptographic keys stored separately from the data they protect (e.g., in an HSM or dedicated key management service)?
  • Is a formal key rotation schedule documented and enforced (e.g., annual rotation for data encryption keys)?
  • Is access to cryptographic keys restricted to the minimum number of authorized custodians using role-based access controls?
  • Is there a documented and tested procedure for cryptographic key revocation and replacement in the event of key compromise?
  • Are all key management activities (generation, distribution, rotation, destruction) logged and retained for audit purposes?

Backup & Archival Encryption

Confirm that backup copies of regulated data are encrypted using the same standards applied to production data.

  • Are all backups containing regulated data encrypted using AES-256 or equivalent before transmission to backup storage?
  • Are off-site or cloud backup destinations verified to enforce encryption at rest independently of the source system?
  • Are backup encryption keys stored separately from the backup data and managed under the key management policy?
  • Has the decryption and restoration of encrypted backups been tested successfully within the past 6 months?
  • Are backup media (tapes, portable drives) containing regulated data physically secured and encrypted?

Endpoint & Mobile Device Encryption

Validate that encryption is enforced on all endpoints, laptops, and mobile devices that access or store regulated data.

  • Is full-disk encryption (e.g., BitLocker, FileVault, LUKS) enforced on all company-issued laptops and workstations?
  • Is encryption enforcement on endpoints verified through MDM or endpoint management platform compliance reporting?
  • Are BYOD (Bring Your Own Device) devices that access regulated data subject to mandatory encryption via MDM policy?
  • Are removable media (USB drives, external hard drives) blocked or encrypted when used to transfer regulated data?
  • Is a photo of the MDM encryption compliance report or endpoint configuration dashboard captured for audit evidence?

Algorithm & Cipher Suite Verification

Confirm that only approved cryptographic algorithms and cipher suites are in active use across all systems in scope.

  • Have TLS cipher suites been reviewed and restricted to NIST-approved suites (e.g., AES-GCM, CHACHA20-POLY1305) on all servers?
  • Is a cipher suite scan or TLS configuration test (e.g., SSL Labs, testssl.sh) performed at least quarterly?
  • Are hashing algorithms restricted to SHA-256 or stronger across all applications (code signing, certificates, password storage)?
  • Is there a documented process to evaluate and migrate cryptographic algorithms in response to newly identified weaknesses or deprecations?
  • Are any additional findings or observations from this encryption verification review recorded below?
