To prevent unauthorized access, what principle should be applied to user access in cloud environments?

The principle of least privilege is essential in cloud environments to prevent unauthorized access. This principle ensures that users are granted only the minimum level of access necessary to perform their job functions. By limiting access rights, the attack surface is reduced, thereby decreasing the likelihood of accidental or malicious data breaches.

Applying least privilege means that if a user's account is compromised, the potential damage is minimized because the account does not have excessive permissions. This approach also aids in maintaining compliance with regulatory requirements, as it emphasizes the need for careful management of user permissions and access controls.

In a cloud environment, where resources and data can be accessed remotely, enforcing least privilege becomes even more critical. It supports a robust security posture by minimizing unnecessary exposure to sensitive data and systems, creating a layered security approach that enhances overall protection against potential threats.
