AWS Certified Cloud Practitioner

Explanation

The principle of least privilege means giving users only the minimum permissions necessary to perform their specific job functions.

Why Option B is correct:

• This directly implements the principle of least privilege by granting access only to resources needed for assigned tasks
• It minimizes security risks by reducing the attack surface
• It prevents accidental or intentional misuse of unnecessary privileges

Why other options are incorrect:

• Option A: Granting access to all AWS services violates the principle by providing excessive permissions
• Option C: While documentation is good practice, it doesn't inherently implement the principle of least privilege
• Option D: Providing extra access "just in case" directly contradicts the principle of least privilege

Key Takeaway: The principle of least privilege is a fundamental security concept that helps reduce security risks by limiting user permissions to only what is absolutely necessary for their specific role.
