What does the principle of "least privilege" entail?

• A. Users have full access to all network resources
• B. Users are restricted to the minimum access necessary
• C. Users can share their access rights with others
• D. Users are granted access based on their seniority

Answer: (B)

The principle of "least privilege" entails that users are provided with the minimum level of access necessary to perform their job functions effectively. This approach limits the potential damage that can occur from accidents or malicious actions by reducing the number of users who have access to sensitive data and critical systems. By restricting access to only what is necessary, organizations can enhance their security posture, prevent unauthorized actions, and minimize the risk of exposure to sensitive information. This principle is fundamental in cybersecurity practices as it promotes a more controlled and secure environment, enabling better monitoring and management of user permissions and reducing the attack surface of the network.
