Encryption Policy Free Template

Here is a full Encryption Policy aligned with SOC 2 (CC6.1, CC6.2) and ISO/IEC 27001:2022 (Controls A.8.24 – A.8.28):

1. Document Control

  • Document Title: Encryption Policy

  • Document Identifier: POL-ALL-005

  • Version Number: v1.0

  • Approval Date: <23 June 2025>

  • Effective Date: <23 June 2025>

  • Review Date: <23 June 2026>

  • Document Owner: <Chief Information Security Officer>

  • Approved By: <Information Security Governance Committee>

2. Purpose

The purpose of this Encryption Policy is to define the requirements and standards for using encryption to protect sensitive information stored, processed, or transmitted by . Encryption is a critical control for maintaining confidentiality and integrity, especially for personal data, financial records, intellectual property, and other proprietary information.

This policy ensures that implements strong encryption methods across all systems, aligns with regulatory and industry expectations, and mitigates the risk of data breaches, interception, or unauthorized access. It supports compliance with SOC 2 Trust Services Criteria CC6.1 and CC6.2, and ISO/IEC 27001:2022 Controls A.8.24 through A.8.28, which mandate secure cryptographic controls and key management practices.

3. Scope

This policy applies to all employees, contractors, and third parties who use or manage systems handling data. It covers:

  • Data at rest (on endpoints, servers, databases, backups, removable media)

  • Data in transit (over email, networks, web, cloud services, APIs)

  • Data within SaaS applications and cloud storage

  • Cryptographic keys and key management systems

This policy applies to both company-owned and third-party-managed infrastructure where company data is stored or transmitted. Exceptions must be documented and approved through the established exception process.

4. Policy Statement

mandates the use of strong encryption to safeguard sensitive and regulated data. The organization shall:

  1. Use only approved encryption algorithms and configurations for all cryptographic implementations (see Section 5).

  2. Encrypt sensitive data at rest and in transit using minimum standards outlined in this policy.

  3. Enforce encryption for all remote access, wireless communication, portable devices, and mobile endpoints.

  4. Prohibit the use of proprietary or unvetted cryptographic methods without formal approval.

  5. Store encryption keys securely, separate from the data they protect, using managed key management systems.

  6. Conduct annual reviews of cryptographic implementations and key rotation schedules.

5. Safeguards

enforces the following encryption standards and controls:

Category

Requirement

Data at Rest

AES-256 encryption required for file systems, databases, and backup media

Data in Transit

TLS 1.2 or higher for web, APIs, email; IPsec for internal VPN connections

Endpoints

Full-disk encryption required on laptops and mobile devices (e.g., BitLocker, FileVault)

Removable Media

Encrypted USB drives must use hardware encryption with FIPS 140-2 compliance

Email

S/MIME or TLS-based email encryption required for sensitive communications

Cloud Platforms

Enforced encryption for object storage (e.g., AWS S3), EBS, and KMS key use

Key Management

Centralized Key Management System (KMS) with role-based access and audit logs

Key Rotation

Keys must be rotated at least annually or upon compromise/role change


Template

All encryption technologies must be reviewed and approved by the Information Security Team before implementation.

6. Roles and Responsibilities

  • CISO: Ensures encryption strategy aligns with business and regulatory requirements; reviews and approves deviations.

  • Information Security Team: Maintains encryption standards, performs audits, and oversees key management platforms.

  • IT Operations: Implements encryption on systems and verifies technical controls during setup and maintenance.

  • Application Developers: Incorporate encryption into system design and ensure APIs/services transmit data securely.

  • Employees and Contractors: Use only company-approved tools for handling sensitive data and follow encryption procedures.

7. Compliance and Exceptions

Compliance will be monitored through:

  • Technical control audits (e.g., endpoint encryption status, TLS scans)

  • Key usage and rotation logs

  • Vendor assessments to verify encryption in third-party systems

All exceptions must be formally documented with risk justification and approved by the CISO. A mitigation plan must be submitted and reviewed quarterly until resolved.

8. Enforcement

Violations of this policy may result in:

  • Immediate revocation of system access

  • Disciplinary actions in accordance with HR policies

  • Mandatory retraining

  • Contract suspension or termination for third-party violators

Where applicable, incidents may be reported to regulators or result in legal liability. Enforcement will be proportional to the risk and documented per case.

  • POL-ALL-003: Access Control Policy

  • PRC-ALL-007: Cryptographic Key Management Procedure

  • ISO/IEC 27001:2022 A.8.24–A.8.28

  • SOC 2 Criteria: CC6.1, CC6.2

10. Review and Maintenance

This policy must be reviewed annually or after any material change in regulatory requirements, technology landscape, or data handling procedures. The CISO is responsible for initiating and coordinating the review. Changes must be tracked and communicated to all relevant stakeholders.
