Which security model incorporates the concepts of confidentiality, integrity, and availability?

The C.I.A. Model, which stands for Confidentiality, Integrity, and Availability, serves as a foundational principle in information security. This model emphasizes the importance of protecting data in three main areas:

1. Confidentiality ensures that information is accessible only to those authorized to view it. This involves implementing measures to prevent unauthorized access, such as encryption and access controls.

2. Integrity focuses on maintaining the accuracy and trustworthiness of data. This means protecting data from being altered or destroyed by unauthorized users, as well as ensuring that any changes to data are done in a controlled and authorized manner.

3. Availability guarantees that information is accessible to authorized users when needed. This involves ensuring that systems are resilient against attacks and failures, with proper backup and recovery procedures in place.

While other models like the Bell-LaPadula Model and the Clark-Wilson Model address specific aspects of information security, they do so within more limited frameworks. The Bell-LaPadula Model primarily emphasizes confidentiality, while the Clark-Wilson Model focuses on integrity in the context of commercial applications. The C.I.A. Model, by encompassing all three pillars—confidentiality, integrity, and availability—provides a holistic approach to protecting information assets
