Question

What is the best definition of a security model?

A. A security model is the process of formal acceptance of a certified configuration.
B. A security model provides a framework to implement a security policy.
C. A security model states policies an organization must follow.
D. A security model is a technical evaluation of each part of a computer system to assess its concordance with security standards.

Answer 1

The most accurate definition of a security model is that it provides a framework for implementing security policies within an organization.

Step-by-step explanation:

The best definition of a security model is "B. A security model provides a framework to implement a security policy." This aligns with the general understanding of models as they are used across various fields. Specifically, in the context of information security, a security model is a theoretical representation that outlines how security measures and controls will be applied within an organization. Models serve as an essential abstraction to understand complex systems and can be made up of equations, physical representations, or computer representations, among others. In practice, a security model is essential for organizations to ensure that their computationally and mathematically based security architecture aligns with their broader security policies and objectives.
