The Open Group information security management maturity model' (O-ISM3) is an Information Security Management Framework that provides an approach for designing, planning, implementing, and governing information security management systems.[citation needed]


The original motivation behind O-ISM3 development was to narrow the gap between theory and practice for information security management systems, and the trigger was the idea of linking security management and maturity models. O-ISM3 strove to keep clear of a number of pitfalls with previous approaches.[1]

The project looked at Capability Maturity Model Integration, ISO 9000, COBIT, ITIL, ISO/IEC 27001:2013, and other standards, and found some potential for improvement in several fields, such as linking security to business needs, using a process based approach, providing some additional details (who, what, why) for implementation, and suggesting specific metrics, while preserving compatibility with current IT and security management standards.[citation needed]


The Open Group provides O-ISM3 free of charge to organisations for their own internal noncommercial purposes.[citation needed]
