Port scanning is used to identify which ports are open. What does this typically help determine?

• A. To identify open ports and services on a target
• B. To patch vulnerabilities automatically
• C. To encrypt data in transit
• D. To monitor network latency

Answer: (A)

Port scanning is about mapping the reachable surface of a host by revealing which ports are open and what services are listening behind them. When you probe a range of ports, you learn not only which ports respond but also identify the service type (and sometimes its version) running on those ports. This information shows what the host is exposing to the network, helping you assess potential entry points, misconfigurations, or outdated services that could be vulnerable. It’s a discovery step that informs defense and remediation planning. This activity isn’t about automatically patching vulnerabilities, encrypting data in transit, or measuring network performance. Those are separate concerns—patching and encryption are applied protections, while latency monitoring is a performance metric. Port scanning focuses on discovering exposed services to understand and secure the system.
