PCI-DSS Requirement 3.4 Statement

Use this statement in your PCI-DSS documentation:

REQUIREMENT 3.4 COMPLIANCE STATEMENT

HeliosDB implements AES-256-GCM encryption for all cardholder data backups.
AES-256 exceeds PCI-DSS Requirement 3.4 minimum encryption standard (3DES).

Encryption Details:
- Algorithm: AES-256-GCM (NIST SP 800-38D)
- Key Management: Customer-managed via AWS KMS, Azure Key Vault, or local HSM
- Automatic: Yes (transparent to payment processing system)
- Key Rotation: 90-day cycle (automatic or manual)
- Validation: Daily automated integrity verification

Cardholder data encrypted: 100% in backups
Cardholder data unencrypted: 0% (encryption mandatory)

This implementation satisfies PCI-DSS Requirement 3.4 for encryption of
stored cardholder data.

Assessment Result: ✅ FULLY COMPLIANT

How to Document PCI-DSS Compliance

Step 1: Self-Assessment Questionnaire (SAQ)

Question 3.4: “Is cardholder data encrypted at rest?”
- Answer: YES
- Evidence: AES-256-GCM implemented in backup_encryption module
Question 3.5: “Are cryptographic keys managed securely?”
- Answer: YES
- Evidence: Customer-managed keys via KMS (never stored by HeliosDB)
Question 8.3: “Is backup access restricted?”
- Answer: YES
- Evidence: Role-based access control (RBAC) for backup operations

Step 2: Describe Your Encryption Process

Backup Process:
1. Database state captured
2. Data compressed (LZ4)
3. Data encrypted (AES-256-GCM)
4. AEAD authentication tag added
5. Encrypted backup uploaded to S3/GCS/Azure
6. Encryption key never stored in HeliosDB

Result: Cardholder data is cryptographically protected at rest

Step 3: Testing & Validation

Annual Test:
1. Create backup with test cardholder data
2. Modify one byte in encrypted backup
3. Attempt to restore
4. Verify restoration fails (authentication tag mismatch)
Result: Encryption integrity verified ✅
