Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Defense in depth
Why it's wrong here
Defense in depth layers controls (firewalls, patching, monitoring) to slow attackers, but it does not limit each employee's data reach. It is tempting because it is a foundational security principle, and it would be the right answer if the question asked how to protect systems against multiple attack vectors.
- ✗
Separation of duties
Why it's wrong here
Separation of duties splits a sensitive task across people to prevent fraud, such as requiring two approvals for payments; it does not restrict data visibility to job need. It is tempting because it also limits insider abuse, and it would be correct if the scenario involved one person controlling an entire critical transaction.
- ✗
Mandatory access control
Why it's wrong here
Mandatory access control enforces administrator-defined labels and clearances rather than job function, and it is typically used in military or high-classification environments. It is tempting because it restricts access by policy, but it would be correct only where data sensitivity labels, not least privilege, drive authorisation decisions.
- ✓
Least privilege
Why this is correct
Least privilege grants users only the minimum access needed for their job tasks, directly satisfying the requirement that employees reach solely the data necessary for their functions. It limits blast radius from compromised or misused accounts.
