This International Standard has been prepared to provide requirements for establishing, implementing, maintaining and continually improving an information security management system. The adoption of an information security management system is a strategic decision for an organization. The establishment and implementation of an organization’s information security management system is influenced by the organization’s needs and objectives, security requirements, the organizational processes used and the size and structure of the organization. All of these influencing factors are expected to change over time.
The information security management system preserves the confidentiality, integrity and availability of information by applying a risk management process and gives confidence to interested parties that risks are adequately managed. It is important that the information security management system is part of and integrated with the organization’s processes and overall management structure and that information security is considered in the design of processes, information systems, and controls. It is expected that an information security management system implementation will be scaled in accordance with the needs of the organization.
This International Standard can be used by internal and external parties to assess the organization’s ability to meet the organization’s own information security requirements.
The order in which requirements are presented in this International Standard does not reflect their importance or imply the order in which they are to be implemented. The list items are enumerated for reference purpose only.
ISO/IEC 27001 is one of the world’s most popular standards and this ISO certification is very sought after, as it demonstrates a company can be trusted with information because it has sufficient controls in place to protect it.
Google, Apple, Adobe, Oracle and many other tech giants, financial institutions, health services providers, insurance companies, education institutions, manufacturing and service companies, large and small business around the world have decided to implement this standard and to get this certification as a proof of their capability to protect the confidentiality, integrity and availability of the information they process. ISO/IEC 27002 is a code of practice – a generic, advisory document, not a formal specification such as ISO/IEC 27001. It recommends information security controls addressing information security control objectives arising from risks to the confidentiality, integrity and availability of information. Organizations that adopt ISO/IEC 27002 assess their own information risks, clarify their control objectives and apply suitable controls (or indeed other forms of risk treatment) using the standard for guidance.
