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. [2]
A maturity model is a framework for measuring an organization's maturity, or that of a business function within an organization, [1] with maturity being defined as a measurement of the ability of an organization for continuous improvement in a particular discipline (as defined in O-ISM3 [dubious – discuss]). [2]
The "definition" of maturity given in O-ISM3 (definition in quotes, because as a definition it is sorely lacking - in part because it uses the word maturity itself in defining itself) is, in full: Selected ISM3 processes collected together and operated at a sufficient capability determine an organization’s information security management ...
The maturity model goes beyond a mere statement of the principles by beginning to define characteristics of various levels of recordkeeping programs. For each principle, the maturity model associates various characteristics that are typical for each of the five levels in the model:
ISO/IEC 21827 does not prescribe a particular process or sequence, but captures practices generally observed in industry. The model is a standard metric for security engineering practices covering the following: Project lifecycles, including development, operation, maintenance, and decommissioning activities
The CMMC framework and model was developed by Office of the Under Secretary of Defense for Acquisition and Sustainment (OUSD(A&S)) of the United States Department of Defense through existing contracts with Carnegie Mellon University, The Johns Hopkins University Applied Physics Laboratory, and Futures, Inc. [1] The Cybersecurity Maturity Model ...
Modeling Maturity Levels is a classification system defined by Anneke Kleppe and Jos Warmer in their book MDA Explained (published by Addison-Wesley). The levels characterize the role of modeling in a software project. The concept shows resemblance to the way software processes are rated with the Capability Maturity Model. There are 6 levels ...
The full representation of the Capability Maturity Model as a set of defined process areas and practices at each of the five maturity levels was initiated in 1991, with Version 1.1 being published in July 1993. [3] The CMM was published as a book [4] in 1994 by the same authors Mark C. Paulk, Charles V. Weber, Bill Curtis, and Mary Beth Chrissis.
