What is BS ISO/IEC 27001?

BS ISO/IEC 27001:2005 (BS 7799-2:2005) is the new international standard that provides a specification for ISMS and the foundation for third-party audit and certification. The standard is complementary to the new standard BS ISO/IEC 17799:2005 (BS 7799-1:2005).
The basic objective of the standard is to help establish and maintain an effective information management system, using a continual improvement approach. It implements OECD (Organization for Economic Cooperation and Development) principles governing security of information and network systems.
The new standard replaces BS 7799-2:2002.

What is BS ISO IEC 27001

Is BS 7799-2:2002 still a valid standard?

BS 7799-2:2002 has been withdrawn now that BS ISO/IEC 27001:2005 (BS 7799-2:2005) has been published. Those companies certified/registered to BS 7799-2:2002 will need to make the transition to the new standard.

Why does the new standard have a new identifier, name and number?

To identify the standard as in international standard the identifier and number has to change. The new name reflects the name of the ISO committee working on the standard, and now more clearly defines the purpose of the standard. However the standard is also dual numbered BS 7799-2:2005.
Eventually, BS ISO/IEC 27001 will be one of a number of security standards published as part of the BS ISO/IEC 27000 series. BS ISO/IEC 27002 and BS ISO/IEC 27004 are likely to be produced in the next few years.

Is ISO/IEC 27001 the same as BS ISO/IEC 27001?

Yes. ISO/IEC 27001 is the “base” international standard. BS ISO/IEC 27001 is the version published by the UK National Standards Body (BSI British Standards). The content is identical.

It is harmonised to work with other management system standards such as ISO 9001 and ISO 14001 and will assist in the integration and operation of an organization’s overall management system.
