Final answer:
Defense in Depth is the concept in security that utilizes multiple layers of controls to protect information, ensuring that if one line of defense fails, others are in place to maintain security.
Step-by-step explanation:
The concept that the deployment of multiple types of controls provides better security than using a single type of control is known as Defense in Depth. This strategy involves layering security mechanisms to protect valuable data and information systems. If one control fails, another steps in to thwart various attacks. This approach is analogous to having multiple layers of defense in a castle, where if an attacker breaches the outer wall, they would still have to navigate additional defenses before reaching the heart of the castle.
Single Sign-On (SSO) is a user authentication process that permits a user to access multiple applications with one set of login credentials. Least Privilege is a security principle that restricts user access rights to only what is strictly required to perform their job. Role-Based Access Control (RBAC) assigns access rights based on the roles within an organization.
