"The ability to distinguish the difference between need to know and least privilege is madly overlooked for this exam! Great work Yani!"– Luke Ahmed
Today is Day 13 of Yihenew’s CISSP study plan, focusing on Need-to-Know vs. Least Privilege — two access control principles that often get confused on the exam.
Key Areas Covered:
Need-to-Know — restricts access to only the specific information required for a task
Least Privilege — gives users the minimum level of access rights to perform their job
CISSP Exam Tie-In — need-to-know focuses on information, least privilege focuses on permissions
Real-World Connection — both reduce risk of insider threats and accidental data exposure
Quick CISSP Practice QuestionWhich principle ensures a financial analyst can only view salary reports, but not modify them?
A. Separation of Duties
B. Need-to-Know
C. Least Privilege
D. Accountability
✅ Correct Answer: B. Need-to-Know
Explanation: Need-to-know restricts access to information based on job role. Least privilege relates to the level of access granted, while separation of duties divides responsibilities.
