ISM³
The Information Security Management Maturity Model (ISM³ or ISM-cubed) The Information Security Management Maturity Model (ISM³ or ISM-cubed) extends ISO9001 quality management principles to information security management (ISM) systems. Rather than focusing on controls, it focuses on the common processes of information security, which are shared to some extent by all organizations. Under ISM³, the common processes of information security are formally described, given performance targets and metrics, and used to build a quality assured process framework. Performance targets are unique to each implementation and depend upon business requirements and resources available. Altogether, the performance targets for security become the Information Security Policy. The emphasis on the practical and the measurable is what makes ISM3 unusual, and the approach ensures that ISM systems adapt without re-engineering in the face of changes to technology and risk.
