Cyber security notes

2. The Cybersecurity Cube

Cybersecurity professionals are best described as experts charged with the protection of cyberspace. John McCumber is one of the early cybersecurity experts, developing a commonly used framework called the McCumber Cube or the Cybersecurity Cube. This is used as tool when managing the protection of networks, domains and the Internet. The Cybersecurity Cube looks somewhat like a Rubik's Cube.

The first dimension of the Cybersecurity Cube includes the three principles of information security. Cybersecurity professionals refer to the three principles as the CIA Triad. The second dimension identifies the three states of information or data. The third dimension of the cube identifies the expertise required to provide protection. These are often called the three categories of cybersecurity safeguards.

The chapter also discusses the ISO cybersecurity model. The model represents an international framework to standardize the management of information systems.
