Information Security Management System Policy

1 Introduction This policy defines how Information Security will be set up, managed, measured, reported on and developed within [Organisation name]. The International Standard for Information Security, BS ISO/IEC 2700:2005 (referred to in this document as ISO/IEC 27001), is a development of the earlier British Standard, BS 7799. [Organisation name] has decided to pursue full certification to ISO/IEC 27001 in order that the effective adoption of Information Security Best Practice may be validated by an external third party.

2 Scope of the ISMS For the purposes of certification within [Organisation Name], the boundaries of the Information Security Management System are defined as follows: [Define the scope of the ISMS in terms of the characteristics of the business, the organisation, its location, assets and technology. Include details of and justification for any exclusions from the scope.]

3 Information Security Requirements A clear definition of the requirements for information security will be agreed and maintained with the business so that all ISMS activity is focussed on the fulfilment of those requirements. Statutory, regulatory and contractual requirements will also be documented and input to the planning process. Specific requirements with regard to the security of new or changed systems or services will be captured as part of the design stage of each project. It is a fundamental principle of the [Organisation Name] Information Security Management System that the controls implemented are driven by business needs and this will be regularly communicated to all staff through team meetings and briefing documents.

4 Management Commitment Commitment to Information Security extends to senior levels of the organisation and will be demonstrated through this ISMS Policy and the provision of appropriate resources to provide and develop the ISMS and associated controls. Top management will also ensure that a systematic review of performance of the programme is conducted on a regular basis to ensure that quality objectives are being met and quality issues are identified through the audit programme and management processes. Management Review can take several forms including departmental and other management meetings.

5 Management Representative The [IT Manager] shall have overall authority and responsibility for the implementation and management of the Information Security Management System, specifically:     

The identification, documentation and fulfilment of information security requirements Implementation, management and improvement of risk management processes Integration of processes Compliance with statutory, regulatory and contractual requirements Reporting to top management on performance and improvement

6 Framework for Setting Objectives and Policy An annual cycle will be used for the setting of objectives for Information Security, to coincide with the budget planning cycle. This will ensure that adequate funding is obtained for the improvement activities identified. These objectives will be based upon a clear understanding of the business requirements, informed by the annual management review with stakeholders. ISMS objectives will be documented for the relevant financial year, together with details of how they will be achieved. These will be reviewed on a quarterly basis to ensure that they remain valid. If amendments are required, these will be managed through the change management process. In accordance with ISO/IEC 27001:2005 the following control objectives and policy statements will be adopted by [Organisation Name]. These will be reviewed on a regular basis in the light of the outcome from risk assessments and in line with the Risk Treatment Plan (document reference ISMS04007).
