However, some core documents are generally considered essential for an ISO 27001-compliant ISMS:
• Information Security Policy: This high-level document outlines the organization's commitment to information security and provides the overall direction for the ISMS.
• Scope of the ISMS: Clearly defines the boundaries of the ISMS, specifying which information assets and processes are included.
• Risk Assessment and Treatment Plan: Identifies potential information security risks, assesses their likelihood and impact, and outlines controls to mitigate them.
• Statement of Applicability (SoA): Select relevant security controls from ISO's Annex A, explaining how they are implemented or why they are not applicable.
