Guide: Understanding and Answering Questions on Least Privilege

Understanding Least Privilege:
The concept of least privilege denotes the practice of limiting access rights for users to the minimal level that allows them to perform their tasks. It is an essential principle in information security.

Importance of Least Privilege:
Implementing least privilege is vital as it reduces the risk associated with malicious attacks and data breaches, minimizes exposure of sensitive information, lowers system susceptibility to viruses and malware, and prevents inadvertent errors that affect system stability.

How it Works:
It works by starting each user with minimal privileges and then permitting additional rights only as necessary for performing sanctioned activities. All unnecessary privileges are strictly avoided, thereby enhancing security.

Exam Tips: Answering Questions on Least Privilege:
During the exam, keep these tips in mind:

• Understand that it is about restricting user access as much as possible without affecting job duties.
