Which GUI tool is used for viewing ports and connections to detect trojans?

• A. Process Monitor
• B. TCPview
• C. Autoruns for Windows
• D. Splunk

Answer: (B)

When you want to spot trojans, you need a picture of what the program is doing on the network at a glance. A tool that shows every open port and active connection, along with which process owns each connection, makes it possible to identify suspicious, unfamiliar activity right away. TCPView provides exactly that: a real-time list of all TCP and UDP endpoints, showing local and remote addresses, the connection state, and the associated process name and PID. With this view, you can quickly notice odd connections to unknown hosts or unusual ports being used by a process that you don’t recognize, which is a common sign of malware trying to “call home” or exfiltrate data. You can also refresh the list to watch for new activity or terminate a troublesome connection or process directly from the tool. Other options serve different purposes. Process Monitor tracks file system, registry, and process activity but not live network connections. Autoruns lists programs that run at startup, not current network activity. Splunk collects and analyzes logs, which is powerful for forensic analysis and large-scale monitoring but isn’t a lightweight GUI focused on viewing live ports and connections. That scoped focus is why TCPView is the best choice for detecting trojans by examining ports and their associated processes.
