ISO 27001 Understanding The Organisation And Its Context

What is ISO 27001 Understanding The Organisation And Its Context?

Understanding the organisation and its context is the process of defining what the internal and external issues are to the organisation that directly impact the information security system and addressing or accepting them.

In February 2024 it was updated to include the need to document if climate change is a relevant issue.

What is ISO 27001 Clause 4.1?

ISO 27001 Clause 4.1 ISO 27001 Understanding the organisation and its context is an ISO 27001 clause and a requirement of ISO/IEC 27001:2022 Information security, cybersecurity and privacy protection — Information security management systems to get ISO 27001 certification.

The organisation shall determine external and internal issues that are relevant to its purpose and that affect its ability to achieve the intended outcome(s) of its information security management system.

The organisation shall determine whether climate change is a relevant issue.
