Information Management System (ISMS) in accordance with ISO 27001:2005

Information security management system

An information security management system (ISMS) is a set of policies concerned with information security management. The idiom arose primarily out of ISO/IEC 27001.

The governing principle behind an ISMS is that an organization should design, implement and maintain a coherent set of processes and systems to manage risks to its information assets, thus ensuring acceptable levels of information security (usually summarised as confidentiality, integrity and availability).
As with all management processes, an ISMS must remain effective and efficient in the long term, adapting to changes in the internal organization and external environment. ISO/IEC 27001 therefore incorporates the typical "Plan-Do-Check-Act" (PDCA), or Deming cycle, approach:

The Plan phase is about designing the ISMS, assessing information security risks and selecting appropriate controls.

The Do phase involves implementing and operating the controls.

The Check phase objective is to review and evaluate the performance (efficiency and effectiveness) of the ISMS.

In the Act phase, changes are made where necessary to bring the ISMS back to peak performance.

The best known ISMS is described in ISO/IEC 27001 and ISO/IEC 27002 and related standards published jointly by ISO and IEC.
Another competing ISMS is Information Security Forum's Standard of Good Practice (SOGP). It is more best practice-based as it comes from ISF's industry experiences.

Other frameworks such as COBIT and ITIL touch on security issues, but are mainly geared toward creating a governance framework for information and IT more generally.
Information Security Management Maturity Model (known as ISM-cubed or ISM3) is another form of ISMS. ISM3 builds on standards such as ISO 20000, ISO 9001, CMM, ISO/IEC 27001, and general information governance and security concepts. ISM3 can be used as a template for an ISO 9001-compliant ISMS. While ISO/IEC 27001 is controls based, ISM3 is process based and includes process metrics. A Capability Maturity Model for system security was standardized in ISO/IEC_21827.

Information Security Management Systems Registration
In order to be awarded a BSI certificate of registration for your Information Security Management System, you must pass an assessment by a BSI auditor to the standard ISO/ IEC 27001:2005.
BSI registration of your ISMS delivers a number of valuable benefits:

Commercial Credibility, Trust and Confidence
Your customers can feel confident of your commitment to keeping their information safe. Registration can help set a company apart from its competitors and in the marketplace. Already, international invitations to tender are starting to require ISO/IEC 27001 compliance.
Cost Savings
The cost of a single information security breach can be significant; the cost of several could be catastrophic. Registration reduces the risk of such costs being incurred and this is important to stakeholders and other investors in your business. Possible reduction in insurance premiums can also be realized.
Legal Compliance
Registration demonstrates to competent authorities that the organization observes all applicable laws and regulations. In this matter, the standard complements other existing standards and legislation.
Commitment
Registration helps to ensure and demonstrate commitment at all levels of the organization.
Operating Level Risk Management
Leads to a better knowledge of information systems, their weaknesses and how to protect them. Equally, it ensures a more dependable availability of both hardware and data.
Employee
Improves employee awareness of security issues and their responsibilities within the organization.
Continual Improvement
The regular assessment process will help you to continually use, monitor and improve your management system and processes.
