Which security model is based on the principle of least privilege?

The principle of least privilege is a foundational concept in security that ensures individuals or systems have only the minimal level of access necessary to perform their functions. This minimizes potential damage from accidents or malicious actions. The correct answer relates to the broader concept of access control models, which include various approaches that incorporate the principle of least privilege.

Access Control Models encompass a variety of methods, including Role-Based Access Control, Discretionary Access Control, and Mandatory Access Control, all of which can implement the principle of least privilege in different contexts. However, the term "Access Control Model" itself refers to the overall framework governing how access is granted and enforced, making it the most comprehensive option that ensures adherence to the principle of least privilege in various implementations.

By adopting an access control framework that emphasizes the principle of least privilege, organizations can significantly enhance their security posture, ensuring that users gain access strictly based on the requirements of their role or task. This not only protects sensitive information but also restricts the spread of potential security breaches.
