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 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 ...
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 "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 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.
Implementation maturity matrix, which is an adjusted version of the test maturity matrix found in the test process improvement (TPI) model developed by Sogeti. The IMM matrix allows an organization to gain insight into the current situation of its implementation processes, and how it should pursue the desirable situation (i.e. a higher maturity ...
ISO/IEC 15504 is the reference model for the maturity models (consisting of capability levels which in turn consist of the process attributes and further consist of generic practices) against which the assessors can place the evidence that they collect during their assessment, so that the assessors can give an overall determination of the organization's capabilities for delivering products ...
