Identify the security measure: Software that monitors internet traffic coming into a network.

Question

BlackTom AI · Accepted Answer

A firewall is software (or hardware plus software) that inspects and controls network traffic according to a set of security rules, so the correct choice is d. Firewall.

1. Relevant knowledge points and concepts
- Firewall: device or program that monitors incoming and outgoing network traffic and permits or blocks data packets based on security rules. Can be network-based (at the perimeter) or host-based (on an individual machine).
- User permissions: access controls for users to resources, not a traffic-monitoring tool.
- Network operating system: OS that supports network services (file/print/authentication), not specifically a traffic filter.
- Computer protection software: a broad term (e.g., antivirus, anti-malware) focused on detecting/removing malicious code rather than monitoring network packets.

2. Step-by-step reasoning
- Read the phrase “monitors internet traffic coming into a network.” Key words: “monitors,” “internet traffic,” “coming into a network.”
- Match that description to definitions: a firewall’s primary role is to monitor and control incoming (and outgoing) traffic. Other listed options do not primarily perform this function.
- Therefore the described security measure is a firewall.

3. Intermediate steps (conceptual)
- Consider alternative tools: intrusion detection systems (IDS) also monitor traffic, but IDS is not listed and typically only detects/alerts; a firewall actively enforces rules to allow/block traffic.
- “Computer protection software” (option c) might include antivirus, which scans files and processes, not traffic monitoring at the network perimeter.
- “User permissions” (option a) and “network operating system” (option b) do not match the network-traffic-monitoring role.

4. Why the correct answer is correct
- Firewalls are explicitly designed to inspect packets, apply rules, and protect networks from unauthorized access—exactly matching “monitors internet traffic coming into a network.”

5. Why other options are incorrect (brief)
- a. User permissions: control user access to resources, not network traffic monitoring.
- b. Network operating system: provides network services; not specifically a traffic-monitoring security tool.
- c. Computer protection software: typically refers to antivirus/anti-malware, which scans files/processes rather than monitoring incoming network packets.

Conclusion: The best match to the description is d. Firewall, confirming the provided answer.
