ISO 27001 :2013 Introduction

ISO 27001:2013 is an international standard published by the International Standardization Organization (ISO) and the International Electrotechnical Commission (IEC). ISO 27001:2013 describes how to manage information security in any organization/company/institution or the like. The latest revision of this standard was published on 25th Sep, 2013, is titled as ISO/IEC 27001:2013. 

ISO 27001 can be implemented in any kind of organization/company/institution, profit or non-profit, private or state-owned, small or large. It was written by the world’s best experts in the field of information security and provides methodology for the implementation of information security management in an organization and has been updated to address the requirements of the changed business scenarios.

ISO/IEC 27001:2013 specifies the requirements for establishing, implementing, operating, monitoring, reviewing, maintaining and improving a documented Information Security Management System within the context of the organization's overall business risks. It specifies requirements for the implementation of security controls customized to the needs of individual organizations or parts thereof. 

This ISO standard is designed to ensure the selection of adequate and proportionate security controls that protect information assets and give confidence to interested parties

ISO 27001 Series of Standards

The ISO/IEC 27000 series consists of information security standards published by the International Standards Organization (ISO) and the International Electrotechnical Commission (IEC). The series is designed to provide best practices on information security management based on the risk assessment and to recommend controls within the context of an organization to enable it to implement an Information Security Management System (ISMS).
Since technology and business environments are continuously evolving , the older standards are revised and new standards are developed to address the evolving business landscape. 

At present there are 33 published standards are under the umbrella of 27001 family. However ISO/IEC 27001 is the only certifiable standard against which an organization's Information Security Management System (ISMS) can be audited and certified by an accreditation body. (ISO/IEC 27001:2005 and ISO/IEC 27002:2005 are not included here , considering they are now obsolete after release of new versions).

 All the other standards in the ISO 27000 family are codes of practice which provide non-mandatory best-practice guidelines published and released to support the ISMS based on ISO/IEC 27001. 

The other 27000 series standards are not mandatory and adopting those is at the sole discretion of the organization.

A list of published standards is available at ISO.
About 33 standards have been released and many more in development phase.

Evolution of ISO 27001 as an Information Security Standard

ISO 27001 has become the most popular voluntarily adopted information security standard worldwide against which companies/institutions can get certified, which means that an independent certification body can confirm that the company/institution/organization has implemented information security compliant with ISO/IEC 27001.


There is an interesting history to the development of this standard. A detailed history can be seen at the following link : http://pc-history.org/17799.htm
The first ever security standard was published by Department of Trade and Industry (DTI), UK as "Code of Practice for Information Security Management". The project was taken over by British Standards Institute (BSI) in 1995 and it was revised and published as BS7799.


BSI also released a second part to BS 7799 which formed the implementation part of an ISMS. 


Later ISO considering that this should be made as an international standard, revised and released ISO 17799 (or more formally, ISO/IEC 17799) based on BS 7799. The ISO/IEC 17799 was again revised in November 2005 and was published as ISO 27001:2005.



ISO 27001:2005 became the most popular standard for demonstrating information security management system.
