Control Diversity

Combining different types of controls, such as technical, administrative, and physical, to protect an asset.

Definition

Control diversity ensures that a weakness in one category of control is offset by another category. For example, a policy is backed by technical enforcement and monitored by audits. It is an element of defense in depth.

Example

Remote access is protected by an acceptable use policy, MFA, and quarterly access reviews.

Exam tip

Diversity across control types strengthens layered security.
