Reason (R): The principle of least privilege recommends granting users only the minimum system resources and authorizations needed to perform their assigned functions.
Choose the correct answer.
Explanation:
• Permanent administrator rights give users substantially more ability to modify system configuration and install software than routine work normally requires.
• Least privilege limits permissions to those necessary for the user's assigned tasks and therefore reduces unnecessary exposure.
• Both statements are true, and the Reason correctly explains why routine use of excessive administrative privilege is undesirable.
