What is McCumber model?
The McCumber Cube is a model framework created by John McCumber in 1991 used to establish and evaluate information security programs. This security model has three dimensions and looks like a Rubik’s cube. The second dimension of the cube focuses on protecting data in each of its possible states.
What are the three dimensions of the McCumber Cube?
The three dimensions of the McCumber cube are stated as Information Characteristics, Information States, and Security Countermeasures. Information Characteristics are the three sides of the CIA triangle which are Confidentiality, Integrity, and Availability.
What is the CNSS model?
CNSS (Committee on National Security Systems is a three-dimensional security model which has now become a standard security model for many of the currently operating information systems. The CNSS model has three key goals of security: Confidentiality, Integrity, and Availability. This comprises one dimension.
What are the foundational principles for protecting information systems as outlined in the McCumber Cube?
The goals identified in the first dimension are the foundational principles. These three principles are confidentiality, integrity, and availability, commonly referred to as the CIA Triad. Confidentiality prevents the disclosure of information to unauthorized people, resources, or processes.
Why McCumber Cube is important?
McCumber Cube. The cube brings together desired goals (confidentiality, integrity, and availability), information states (storage, transmission, and processing), and safeguards (policies and practices, human factors, and technology).
What are the 27 cells of the McCumber cube?
To ensure system security, each of the 27 areas must be properly addressed during the security process (McCumber, 1991). The three-dimensional model’s factors are Confidentiality, Integrity, Availability, Policy, Education, Technology Storage, Processing, and Transmission.

What are the three dimensions of cybersecurity?
confidentiality, integrity and availability
The Three Dimensions These three principles are confidentiality, integrity and availability. The principles provide focus and enable cybersecurity specialists to prioritize actions in protecting the cyber world. Use the acronym CIA to remember these three principles.
What are the 3 states of data?
Three states of data is a way of categorizing structured and unstructured data. The three states of data are data at rest, data in motion and data in use. Data can change states quickly and frequently, or it may remain in a single state for the entire life cycle of a computer.
