Which term describes measures that protect a computer network from intruders, including both wired and wireless connections?

• A. Network security
• B. Malware
• C. Phishing
• D. DDoS

Answer: (A)

Network security is the set of measures designed to protect a computer network from intruders and threats, for both wired and wireless connections. It combines policies and technical controls—firewalls that filter traffic, intrusion detection systems that watch for suspicious activity, encryption to keep data in transit private, strong authentication and access controls, secure configurations, and regular patching and network segmentation. For wireless networks, it also includes protections like robust Wi‑Fi encryption (such as WPA3), proper authentication, and safeguards against rogue access points. The other terms point to specific threats or attack methods: malware is harmful software, phishing is a social engineering tactic to steal credentials, and DDoS is an attack that overwhelms services with traffic. Network security, in contrast, is about preventing intrusions across both wired and wireless paths.
