Which concept describes the overall goal of preventing unauthorized access to networks?

• A. Confidentiality
• B. Network Security
• C. Availability
• D. Integrity

Answer: (B)

Preventing unauthorized access to networks is the realm of network security—the set of measures that guard network resources from intruders. It covers authentication and authorization, access controls, firewalls, encryption for data in transit, and monitoring to block or detect unauthorized attempts. This describes the overall aim of protecting the network itself from being accessed by the wrong people, not just protecting data from disclosure (confidentiality) or focusing on uptime (availability) or data accuracy (integrity). So network security is the best fit for describing that broad goal.
