ISO 27001 is a globally recognized standard for managing information security. For businesses seeking to protect sensitive data and demonstrate a commitment to security, compliance with ISO 27001 is essential. One of the most important steps in achieving ISO 27001 certification is developing the right set of documentation ISO 27001 Documents. These documents serve as the backbone for your Information Security Management System (ISMS) and help you align with ISO 27001 requirements.

In this post, we’ll explore the essential ISO 27001 documents every business needs to ensure compliance and safeguard critical information.

1. Information Security Policy

The foundation of your ISMS, the Information Security Policy, outlines your organization’s approach to managing information security. It provides clear instructions on how your business will protect information assets and what controls will be implemented. The policy should be approved by top management and communicated to all employees to ensure everyone understands their role in maintaining security.

Key Elements:

  • Information security objectives
  • Roles and responsibilities
  • Guidelines for handling sensitive information

  • Risk impact and likelihood analysis
  • Threats, vulnerabilities, and existing controls

Key Elements of Risk Treatment Plan:

  • Proposed treatment for each identified risk
  • Assigning responsibility for treatment
  • Evaluation of residual risk after treatment

3. Statement of Applicability (SoA)

The Statement of Applicability is a crucial document that shows how each control in the ISO 27001 Annex A controls list has been applied. It should indicate which controls are in place, why certain controls have been excluded, and how they align with your organization’s risk treatment plan.

Key Elements:

Audit reports document findings and provide insights for corrective actions to address any gaps in your ISMS.

Key Elements:

  • Schedule for audits
  • Audit criteria and scope
  • Corrective action tracking

6. Corrective and Preventive Action Records

When issues arise, ISO 27001 mandates that businesses take corrective or preventive actions to fix them.

These records ensure that your organization learns from incidents and improves its processes over time.

Key Elements:

  • Documentation of non-conformities
  • Root cause analysis
  • Actions taken to resolve issues

7. Access Control Policy

These documents typically include contracts or agreements outlining security expectations, monitoring procedures, and penalties for non-compliance.

Key Elements:

  • Security requirements in supplier contracts
  • Performance monitoring and review
  • Audits and assessments of third-party security

11. Employee Awareness and Training Records
