What is ISO 27001?
ISO 27001, formally known as ISO/IEC 27001:2022, is an international standard for information security management. It provides a framework and guidelines for establishing, implementing, and maintaining an Information Security Management System (ISMS) to protect an organization's information assets.
How ISO 27001 Works
ISO 27001 works by emphasizing a top-down, risk-based approach to information security. It requires organizations to identify and assess information security risks, implement risk management processes, and develop appropriate mitigation strategies. The standard outlines a comprehensive set of security controls categorized into 14 sections, each addressing various aspects of information security such as access control, cryptography, physical security, and incident management.
