Study Notes
McCumber Cube Overview
- A model framework for establishing and evaluating information security programs.
- Provides guidance on enhancing information assurance.
Three Dimensions of the McCumber Cube
- Consists of Desired Goals, Information States, and Security Measures.
Desired Goals
- Focuses on three primary goals:
- Confidentiality
- Integrity
- Availability
Information States
- Encompasses three forms of data handling:
- Storage
- Transmission
