ISO 27001- ISMS
ISO 27001:2013 standard was published in October 2005, essentially replacing the old BS7799-2 standard. The ISO 27000 family of standards helps organizations keep information assets secure. If you are concerned about protection of assets especially information assets, ISMS provides a control framework to protect the (information) assets. This combines management controls (such as ISMS framework, ISMS policy), technical controls (malware management, access controls, network perimeter, encryption), procedural controls (e.g. document management), personnel controls (e.g. background screening) to name a few.
The controls combine preventive, detective, restorative, maintenance and monitoring controls. 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.
