Mandatory Documents According To The ISO 27001:2022

by Nash V


To achieve ISO 27001 certification, organizations must establish, implement, and maintain comprehensive policies, procedures, and controls to manage information security risks effectively. These policies and procedures are documented in a series of mandatory documents, which form the backbone of an organization's ISMS.

These mandatory documents serve as a roadmap for organizations, guiding them in creating, implementing, and maintaining their information security management systems. They provide clarity, consistency, and a structured approach to managing information security risks across the organization. These documents are essential for achieving ISO 27001 certification, as they demonstrate the organization's commitment to information security and its ability to meet the standard's requirements.

Mandatory Documents According To The ISO 27001:2022

What Are These Mandatory Documents?

These mandatory documents include policies, plans, procedures, and records that cover various aspects of information security, such as:

  • ISMS Scope Document- The scope of an ISO 27001 document refers to defining the boundaries and limits of the ISMS, outlining what information and assets are included and covered by the standard's requirements.
  • Information Security Policy- The policy establishes a clear and firm stance on information security, signifying its importance as a strategic priority. This policy defines high-level objectives and responsibilities, assigning roles for individuals and departments, thus providing a framework for decision-making and action related to security measures.
  • Risk Assessment and Treatment Methodology- This methodology guides organizations in identifying, assessing, and mitigating information security risks effectively. It outlines a structured approach to evaluate potential vulnerabilities, threats, and the impact of security incidents on the organization's information assets.
  • Statement of Applicability- The Statement of Applicability document serves as a central reference outlining the specific security controls and measures an organization has selected to address its information security risks. It includes a comprehensive list of controls from Annex A of the ISO 27001:2022 standard, each evaluated for relevance to the organization's security needs.
  • Risk Treatment Plan- Risk Treatment Plan serves as a comprehensive roadmap for addressing and mitigating identified information security risks. This document outlines the specific actions, controls, and countermeasures an organization intends to implement to reduce and manage these risks to an acceptable level.
  • IT Assets Register- IT Assests Register is a comprehensive inventory and documentation of all information technology assets within the organization, including hardware, software, and data.
  • Acceptable Use of Assets- Acceptable Use of Assets document outlines the rules and guidelines that employees and authorized users must adhere to when utilizing an organization's information assets, including computers, networks, data, and other IT resources.
  • Incident Management Procedure- Incident Management Procedure provides a structured approach for how an organization should effectively prepare for, respond to, and manage information security incidents.
  • Secure Development Policy- Secure Development Policy helps organizations integrate security into their software development processes, reduce the risk of vulnerabilities and security incidents, and promote a proactive approach to safeguarding information assets through secure software development practices.

How Do These Documents Help You?

These documents can help you in the following ways:

  • Clarity and Consistency: Mandatory documents provide a transparent and standardized framework for implementing ISO 27001. They help organizations follow a structured approach to information security management, ensuring consistency across different departments and processes.
  • Compliance and Certification: ISO 27001 compliance and certification require the existence and proper maintenance of specific mandatory documents. With these documents, organizations may meet the criteria for certification, which can be important for demonstrating commitment to information security to clients, partners, and regulatory bodies.
  • Risk Management: Many mandatory documents, such as the risk assessment and treatment methodology, the Statement of Applicability, and the Risk Treatment Plan, are crucial for identifying, assessing, and managing information security risks. These documents help organizations prioritize and address risks effectively.
  • Accountability: Mandatory documents define roles and responsibilities for information security within the organization. This ensures that individuals and teams understand their obligations, helping to create a culture of accountability for security-related matters.
  • Incident Response: Documents related to incident management, such as the Incident Management Procedure, are crucial for responding to and mitigating security incidents effectively. Having a structured process in place is essential to minimize the impact of security breaches.
  • Continuous Improvement: Mandatory documents encourage organizations to continuously improve by documenting past incidents, risk assessments, and treatment plans. This information helps organizations learn from past experiences and refine their security practices.

Are These Mandatory Documents Enough To Clear ISO 27001 Certification?

The mandatory documents required for ISO 27001:2022 are essential elements of compliance with the standard, and having them in place is a significant step toward certification. However, it's essential to understand that ISO 27001 certification involves a comprehensive process beyond just having the required documents. Certification also includes audits, assessments, and evaluations by accredited certification bodies.

Here are some key points to consider:

  • Documentation: While mandatory documents are crucial, they must be effectively implemented and maintained. The documentation should reflect the organization's actual practices and processes for information security management.
  • Implementation: Certification assessors will review the documentation and the effectiveness of the information security management system (ISMS) in practice. The organization should demonstrate following the documented processes and effectively managing information security risks.
  • Audits and Assessments: The certification process typically involves external audits conducted by accredited certification bodies. These audits evaluate the organization's adherence to ISO 27001:2022 requirements, including the effectiveness of the ISMS.
  • Employee Awareness and Training: The organization should have processes for raising employee awareness about information security and provide necessary training to employees to ensure they understand their roles and responsibilities.
  • Compliance with Legal and Regulatory Requirements: Organizations must demonstrate their commitment to complying with relevant legal, regulatory, and contractual requirements related to information security.


The mandatory documents prescribed by ISO 27001 are the backbone of an organization's information security framework. They provide structure, clarity, and guidance to help organizations effectively identify, assess, and manage information security risks. These documents not only aid in compliance with ISO 27001 requirements but also contribute to the organisation's overall security posture. Achieving ISO 27001 certification requires a comprehensive effort that encompasses creating and maintaining mandatory documents, their practical implementation, and ongoing adherence to information security best practices. Additionally, certification bodies will evaluate the organization's commitment to a culture of security and continual improvement.
