What are the requirements for ISO/IEC 27003:2017?

ISO/IEC 27003:2017 is a guidance document and does not specify requirements for the implementation of an information security management system (ISMS) like ISO/IEC 27001 does. Instead, it provides recommendations and guidance on how to implement and manage an ISMS effectively in accordance with ISO/IEC 27001.

To understand the requirements for ISO/IEC 27001:2013, which is the standard that outlines the requirements for establishing, implementing, maintaining, and continually improving an ISMS, you should refer to ISO/IEC 27001 itself.

Here are the key requirements of ISO/IEC 27001:2013:
  • Context of the Organization: Understand the organization’s context and the needs and expectations of interested parties relevant to information security.
  • Leadership: Ensure top management’s commitment to information security and establish roles, responsibilities, and authorities.
  • Planning: Establish an ISMS policy, conduct risk assessments, and set information security objectives and a plan to achieve them.
  • Support: Allocate resources, provide competence and awareness, and ensure communication and documentation are in place.
  • Operation: Implement and operate controls and processes to manage risks and achieve information security objectives.
  • Performance Evaluation: Monitor and measure information security performance, conduct internal audits, and review the ISMS for effectiveness.
  • Improvement: Continually improve the ISMS based on monitoring, measurement, audit results, and management review.

Overall,these are the high-level requirements of ISO/IEC 27001:2013. ISO/IEC 27003:2017 can provide additional guidance and insights on how to effectively implement these requirements, but it doesn’t specify requirements itself. When an organization wants to implement an ISMS and seek certification, it typically uses ISO/IEC 27001 as the foundation and then refers to ISO/IEC 27003 for guidance on how to meet those requirements effectively.
