In the context of security, what does the principle of Least Privilege primarily ensure?

The principle of Least Privilege is fundamentally about minimizing user access rights to the bare minimum required to perform their job functions. This principle ensures that individuals have access only to the resources necessary for their specific tasks, thereby reducing the risk of unauthorized access or potential damage, whether intentional or accidental. By limiting the access rights, organizations can significantly mitigate the chance of breaches, data loss, and misuse of information.

This practice is vital in enhancing security because it helps to contain potential threats. For instance, if a user account is compromised, the least privilege approach ensures that the attacker has limited access and cannot exploit additional functions or sensitive data that they wouldn't normally have permissions for.

In contrast, options suggesting that users have access to all system functions, that all information is always accessible, or that data should be always encrypted do not align with the focus of the Least Privilege principle, which emphasizes restricted access and the need to safeguard vital data by only providing an individual with necessary permissions.
