History of ISO/IEC 27001 Standard


1992
The Department of Trade and Industry (DTI), which is part of the UK
Government, publish a 'Code of Practice for Information Security Management'.

1995
This document is amended and re-published by the British Standards Institute (BSI) in
1995 as BS7799.

2000
In December, BS7799 is again re-published, this time as a fast tracked ISO standard. It
becomes ISO 17799 (or more formally, ISO/IEC 17799).

2005
A new version of ISO 17799 is published. This includes two new sections, and closer
alignment with BS7799-2 processes..

2005
The latest version of ISMS is known as ISO/IEC 27001:2005

                                                                 4

What is Information


Information Comprises the meanings and interpretations that people place upon the facts
and Data. The value of the information springs from the ways it is interpreted and applied to
make products, to provide services, and so on.

Why Information Security Is Very Important


Financial Information Such as Accounts, Tax Details, Employee Pay roll
Information, Personnel Records if you lost …..?????
If you lost New product Designs data through Human Error, Fire, Theft ???

details and information on their buying trend…..????
Imagine waking up to discover that your IT systems have been hacked.
Your company's financial results have been leaked to the media; your
confidential business plans have been compromised; your employees'
personal files have been posted on the internet

What is Information Security Management
  System

Information Security Management is a process by which the value of each
Organisation information is assessed and, if appropriate, protected on
ongoing basis.
Building a Information Security Management system is achieved through
the “systematic assessment of the systems, technologies and media
contained information, appraisal of the loss of information, cost of
security breaches, and development & deployment of counter
measures to threats.”
If simplify, ISMS provide a platform where organisation recognizes most
valuable spots of in an organisation and builds armor-plating to protect
them.
