- ISO 27001/2
- ISO/IEC 27001, part of the growing ISO/IEC 27000 series of standards, is an information security management system (ISMS) standard published in October 2005 by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Its full name is ISO/IEC 27001:2005 - Information technology -- Security techniques -- Information security management systems -- Requirements but it is commonly known as "ISO 27001".
- It is intended to be used in conjunction with ISO/IEC 27002, the Code of Practice for Information Security Management, which lists security control objectives and recommends a range of specific security controls. Organizations that implement an ISMS in accordance with the best practice advice in ISO/IEC 27002 are likely to simultaneously meet the requirements of ISO/IEC 27001 but certification is entirely optional (unless mandated by the organization's stakeholders).
ISO 27001/2 stipulates a number of principles/ procedures that an auditor should adopt when preparing and carrying out an audit. The audit process is broken down into a number of disparate sections which the company being audited should ideally have appropriate policies and controls in place:
