QuestionQ147

VerifiedIdentity and Access Management (IAM)

A security architect is reviewing an implemented security framework. Following the review, the architect wants to improve security by implementing segregation of duties (SoD) to protect against fraud. Which security model BEST safeguards data integrity?

Explanation

The Clark-Wilson model protects data integrity by requiring well-formed transactions, enforcing segregation of duties so that no single person can complete a sensitive process alone, and maintaining audit records. These controls are designed to reduce fraud and unauthorized data modification.
