A company is implementing a new security policy that mandates the least privilege principle for all user accounts. Which of the following best describes the primary goal of this principle?
- ATo grant users only the necessary permissions to perform their job functions.
- BTo encrypt all sensitive data stored on user workstations.
- CTo regularly audit user activity for compliance with regulatory standards.
- DTo ensure users have unlimited access to resources for maximum productivity.
Show answer & explanationAnswer & explanation
Correct answer: A. To grant users only the necessary permissions to perform their job functions.
The principle of least privilege dictates that users should be granted only the minimum necessary permissions to perform their job functions. This reduces the attack surface and limits the potential damage if an account is compromised.
Why the other options are wrong
- B. Encrypting data is a data protection measure, not the primary goal of the least privilege principle, which focuses on access rights.
- C. Regular auditing is a separate security control, distinct from the principle of least privilege itself.
- D. Unlimited access directly contradicts the principle of least privilege, increasing risk.
Principle of Least Privilege
A security concept in which a user is given the minimum levels of access – or permissions – needed to perform a job function.
- Grants minimum necessary rights.
- Reduces attack surface.
- Limits potential damage from compromise.
Memory trick: Security principles guide protection: Least Privilege limits access, Separation of Duties prevents single points of failure.
