Network security revolves around the setup and use of __________ to control who and how objects are utilized.

• A. authentication, authorization, and permissions
• B. identification
• C. authentication and permissions
• D. packet sniffers

Answer: (A)

Controlling access to resources in a network depends on verifying who a user is and what they’re allowed to do. Authentication is the process that proves the user’s identity, typically through credentials like a username and password, a token, or biometric data. Once identity is established, authorization decides whether that user has permission to access a given object and perform particular actions. Permissions specify the exact rights granted (for example, read, write, or delete) and are enforced through access control mechanisms such as ACLs or role-based access controls. Identification on its own only attempts to establish who a user claims to be, but without authentication there’s no proven identity to authorize. Packet sniffers are tools for capturing and analyzing network traffic, not mechanisms for controlling who can access what or how it’s used. So, combining authentication, authorization, and permissions provides the complete means to ensure that only the right users can access objects and perform only the actions they’re allowed to, which is why this option is the best fit.
