ISO/IEC 27001 is the leading international standard for information‑security management, published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It sets out the requirements for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). Certification demonstrates that an organization follows a risk‑based, systematic approach to protecting data—covering people, processes, and technology—through controls spanning areas such as access management, encryption, incident response, physical security, and supplier oversight.
