Why You Need This Encryption Policy

A well-documented Encryption Policy is essential for organisations pursuing compliance certifications and building trust with customers, partners, and auditors. Without formal documentation, your organisation faces several risks:

  • Audit failures — Auditors specifically check for documented policies. A missing or incomplete policy is one of the most common reasons organisations fail SOC 2, ISO 27001, or other compliance audits.
  • Security gaps — Without clear guidelines, employees and contractors may follow inconsistent security practices, creating vulnerabilities.
  • Regulatory exposure — Many regulations (GDPR, HIPAA, PCI DSS) require documented policies. Non-compliance can result in fines and legal liability.
  • Lost business opportunities — Enterprise customers increasingly require vendors to demonstrate formal security policies before signing contracts.

This Proveably template gives you a professional starting point that covers industry best practices and maps directly to compliance framework requirements.

# Encryption Policy ## 1. Purpose This policy establishes encryption standards for protecting **[Company Name]** data at rest and in transit. ## 2. Data in Transit ### 2.1 Requirements - All external communications must use **TLS 1.2 or higher** - TLS 1.0 and 1.1 are **prohibited** - HSTS headers must be enabled with minimum **1-year** max-age - Certificate transparency logging is required ### 2.2 Approved Cipher Suites - TLS_AES_256_GCM_SHA384 - TLS_AES_128_GCM_SHA256 - TLS_CHACHA20_POLY1305_SHA256 ### 2.3 Internal Communications - Service-to-service communication within VPC may use mTLS or encrypted channels - Database connections must use SSL/TLS ## 3. Data at Rest ### 3.1 Requirements - All databases: **AES-256** encryption enabled - All object storage (S3, GCS): Server-side encryption enabled by default - Laptop disk encryption: **FileVault** (macOS) or **BitLocker** (Windows) mandatory - Backup data: Encrypted with separate key from primary data ### 3.2 Approved Algorithms | Use Case | Algorithm | Key Size | |----------|-----------|----------| | Database encryption | AES-256-GCM | 256-bit | | File encryption | AES-256-GCM | 256-bit | | Password hashing | bcrypt / Argon2id | N/A | | Digital signatures | RSA-2048+ or Ed25519 | 2048+ / 256-bit | ## 4. Key Management ### 4.1 Key Lifecycle - **Generation**: Keys generated using cryptographically secure random number generators - **Storage**: Keys stored in dedicated key management service (AWS KMS, GCP KMS, HashiCorp Vault) - **Rotation**: Encryption keys rotated **annually** or upon suspected compromise - **Destruction**: Old keys securely destroyed after rotation grace period (90 days) ### 4.2 Key Access - Access to encryption keys restricted to authorized personnel and services - Key access logged and audited - No encryption keys stored in source code, environment variables, or configuration files ## 5. Certificate Management - TLS certificates managed via automated tool (Let's Encrypt, AWS ACM) - Certificate expiry monitored with **30-day** advance alerts - Private keys for certificates never shared or transmitted in clear text --- *Approved by: [Name, Title]* *Effective Date: [Date]* *Version: 1.0*
