Question: 1 / 545

What principle allows a user to access server or system files based on provided credentials?

Authorization

Authentication

The principle that allows a user to access server or system files based on provided credentials is authentication. Authentication is the process of verifying the identity of a user or system, typically through credentials such as usernames and passwords. When a user enters their credentials, the system checks these details against a stored database to confirm the user's identity. Only upon successful verification does the system grant access to its resources.

In contrast, authorization follows authentication and refers to the permissions and privileges that a user has once their identity is confirmed. Encryption involves securing data to protect it from unauthorized access, and confidentiality is concerned with ensuring that sensitive information is not disclosed to unauthorized individuals. Understanding these distinctions is crucial for grasping the fundamentals of network security and access control.
