Information is the lifeblood of all organizations and can exist in many forms. It can be printed or written on paper, stored electronically, transmitted by mail or by electronic means, shown in films, or spoken in conversation. In today’s competitive business environment, such information is constantly under threat from many sources. These can be internal, external, accidental, or malicious.

There is a need to establish a comprehensive Information Security Policy within all organizations. You need to ensure the confidentiality, integrity, and availability of both vital corporate information and customer information.

An Information Security Management System (ISMS) is a systematic approach to managing sensitive company information so that it remains secure. It encompasses people, processes and IT systems. ISO/IEC 27001:2005 (formerly BS 7799-2:2002) establish best practices of control objectives and controls in the following areas of information security management:

Security policy;
Organization of information security;
Asset management;
Human resources security;
Physical and environmental security;
Communications and operations management;
Access control;
Information systems acquisition, development and maintenance;
Information security incident management;
Business continuity management;
Compliance.

Application:

The requirements set out in this International Standard are generic and are intended to be applicable to all organizations, regardless of type, size and nature.

Any exclusion of controls found to be necessary to satisfy the risk acceptance criteria needs to be justified and evidence needs to be provided that the associated risks have been accepted by accountable persons. Where any controls are excluded, claims of conformity to this International Standard are not acceptable unless such exclusions do not affect the organization’s ability, and/or responsibility, to provide information security that meets the security requirements determined by risk assessment and applicable regulatory requirements.

If an organization already has an operative business process management system (e.g. in relation with ISO 9001 or ISO 14001), it is preferable in most cases to satisfy the requirements of this International Standard within this existing management system.
