During a routine network assessment, you identify an unknown device connected to the network. Using an ad hoc network discovery method, which tool would efficiently allow you to gather comprehensive data about this device, such as the operating system, open ports, and services running?
Netstat
Wireshark
Ping
Nmap
Nmap is a versatile tool used for network discovery and security auditing. It can effectively identify host details such as the operating system, service versions, and open ports, making it excellent for ad hoc discovery when unknown or unauthorized devices are detected on the network. Wireshark, while powerful for analyzing packet flows, is primarily a packet capture tool and does not inherently provide comprehensive device profiling. Ping is simply a network utility tool to check the reachability of a host on an IP network and does not reveal detailed information about the device’s operating system or running services. Netstat displays active connections and listening ports on the host it’s run from, but it is not used for discovering details about other devices.
