What are the foundational principles for protecting information systems as outlined in the McCumber Cube?

Explanation & Hint:

The McCumber Cube is a model used to assess information security in terms of three dimensions: confidentiality, integrity, and availability (often referred to as the CIA triad). So, the three foundational principles for protecting information systems according to the McCumber Cube are:

Confidentiality: Protecting information from unauthorized access or disclosure to ensure that sensitive data remains confidential.
Integrity: Ensuring the accuracy and reliability of data and information, as well as protecting it from unauthorized alterations.
Availability: Ensuring that information and resources are available and accessible to authorized users when needed.
The other options (Access, Scalability, and Intervention) are not part of the McCumber Cube’s foundational principles but may be important considerations within the broader field of information security.
