Is the importance and complexity of a mandatory record a requirement in ISO 27001?

In the context of ISO 27001, the requirement concerning mandatory records does not hinge on the importance or complexity of the records themselves. ISO 27001 emphasizes the establishment of an Information Security Management System (ISMS) based on a risk management approach. This means that organizations must identify their information security risks and implement controls that are appropriate to their specific context and needs.

While the standard acknowledges that different types of records may carry varying degrees of importance, it does not classify mandatory records based on their complexity or significance. Instead, it establishes a framework that necessitates the maintenance of adequate records to demonstrate compliance with the ISMS framework and to ensure the effectiveness of the implemented controls.

The focus of ISO 27001 is on ensuring that organizations can systematically manage sensitive information, thereby maintaining its confidentiality, integrity, and availability, regardless of the individual characteristics of specific records. Hence, the requirement for having mandatory records as part of the ISMS is clear and is not contingent upon the complexity or importance of those records.
