What encapsulates the "least privilege" principle in firewall security?

The principle of "least privilege" in firewall security is fundamentally about providing users with the minimal level of access required to perform their job functions effectively. This approach mitigates security risks by limiting the permissions and access rights of users, thereby reducing the potential attack surface for security breaches.

By adhering to this principle, organizations can ensure that users only have the necessary permissions they need to carry out their tasks, preventing unauthorized access to sensitive information and critical systems. This can help lower the likelihood of accidental or intentional misuse of resources, as each user's capabilities are restricted just to what they need to do their work.

In contrast, options that suggest granting full access, allowing unrestricted internet browsing, or enabling all users to modify firewall settings contradict the essence of the least privilege principle. These practices can lead to increased vulnerability and potential exploitation of the system, as they do not impose any access limitations that would safeguard against misuse or attack.
