ISO 27001 is an internationally recognized standard for information security management systems (ISMS). It provides a systematic approach for organizations to manage and protect their information assets. The standard is structured around a set of clauses that outline the requirements for establishing, implementing, maintaining, and continuously improving an ISMS. These clauses are essential for achieving ISO 27001 certification and ensuring the security of sensitive information.
Here are the 10 clauses of ISO 27001:
- Scope: This clause defines the boundaries of the ISMS, specifying the information assets and processes it covers. It ensures that the organization's objectives and constraints are clearly documented.
- Normative References: ISO 27001 refers to other standards that provide guidance on information security. This clause highlights those standards and their applicability within the organization.
- Terms and Definitions: In this clause, key terms and definitions related to information security management are provided. It ensures that all stakeholders have a common understanding of the terminology used.
