ISO 27001 (Information Security Managment System)
The ISO 27001 standard was published in October 2005, essentially replacing the old BS7799-2 standard. It is the specification for an ISMS, an Information Security Management System. BS7799 itself was a long standing standard, first published in the nineties as a code of practice. As this matured, a second part emerged to cover management systems. It is this against which certification is granted. Today in excess of a thousand certificates are in place, across the world.
The objective of the standard itself is to “provide a model for establishing, implementing, operating, monitoring, reviewing, maintaining, and improving an Information Security Management System”. Regarding its adoption, this should be a strategic decision. Further, “The design and implementation of an organization’s ISMS is influenced by their needs and objectives, security requirements, the process employed and the size and structure of the organization”.
The standard defines its ‘process approach’ as “The application of a system of processes within an organization, together with the identification and interactions of these processes, and their management”. It employs the PDCA, Plan-Do-Check-Act model to structure the processes.
Information is critical to the operation and perhaps even the survival of your organization. Being certified to ISO/IEC 27001 will help you to manage and protect your valuable information assets.
ISO/IEC 27001 is the only auditable international standard which defines the requirements for an Information Security Management System (ISMS). The standard is designed to ensure the selection of adequate and proportionate security controls.
This helps you to protect your information assets and give confidence to any interested parties, especially your customers. The standard adopts a process approach for establishing, implementing, operating, monitoring, reviewing, maintaining, and improving your ISMS.
Who is it relevant to?
ISO/IEC 27001 is suitable for any organization, large or small, in any sector or part of the world. The standard is particularly suitable where the protection of information is critical, such as in the finance, health, public and IT sectors.
ISO/IEC 27001 is also highly effective for organizations which manage information on behalf of others, such as IT outsourcing companies: it can be used to assure customers that their information is being protected.
