Which of the following is a core principle of cloud security architecture?

Minimizing user access is a fundamental principle of cloud security architecture because it directly relates to the concept of least privilege. This principle advocates that users should have the minimum level of access necessary to perform their job functions. By limiting access, organizations can significantly reduce the potential attack surface, making it more difficult for unauthorized individuals to access sensitive data or resources. This approach not only helps protect against insider threats but also mitigates the risks associated with external attacks, as fewer users with privileged access means fewer opportunities for exploitation.

This principle fits within broader security frameworks and practices, emphasizing the protection of sensitive data and maintaining the integrity and confidentiality of systems. It is vital to implement measures like role-based access control (RBAC) to ensure that permissions are appropriately assigned based on users' roles, thus supporting a robust security posture in cloud environments.

In contrast, other options like decentralizing network controls or centralizing data management may not inherently contribute to security and could introduce complexities. While maximizing data encryption is an essential security practice, it does not address access control, which is crucial for preventing unauthorized access in the first place.
