The Parkerian hexad is a set of six elements of information security proposed by Donn B. Parker in 1998 [1] [2].The Parkerian hexad adds three additional attributes to the three classic security attributes of the CIA triad (confidentiality, integrity, availability).
SOC 2 reports focus on controls addressed by five semi-overlapping categories called Trust Service Criteria which also support the CIA triad of information security: [1] Security - information and systems are protected against unauthorized access and disclosure, and damage to the system that could compromise the availability, confidentiality ...
The CNSS holds discussions of policy issues, sets national policy, directions, operational procedures, and guidance for the information systems operated by the U.S. Government, its contractors or agents that either contain classified information, involve intelligence activities, involve cryptographic activities related to national security, involve command and control of military forces ...

The McCumber Cube. The McCumber Cube is a model for establishing and evaluating information security (information assurance) programs.This security model, created in 1991 by John McCumber, is depicted as a three-dimensional Rubik's Cube-like grid.
CIA (or C-I-A) triad is a widely-accepted information assurance (IA) model which identifies confidentiality, integrity and availability as the fundamental security characteristics of information. The three characteristics of the idealized model are also referred to as IA services, goals, aims and tenets.
Keeping a system secure relies on maintaining the CIA triad: confidentiality (no unauthorized access), integrity (no unauthorized modification), and availability. [5] Although availability is less important for some web-based services, it can be the most crucial aspect for industrial systems. [6]
