CHFI Storage Forensics and File System Analysis Practice Question

During a forensic examination of a Windows system, an analyst runs the Volatility plugin `netscan` on a memory dump. What information does this plugin primarily provide?

⚠ Common exam trap

The EC-CHFI exam often tests the distinction between memory forensics plugins, and the trap here is that candidates confuse `netscan` with `pslist` or `handles`, assuming it provides process lists or file handles instead of network socket data.

Correct answer & explanation

✓

Network connections and listening sockets with associated processes

The Volatility plugin `netscan` is specifically designed to extract network connection information from Windows memory dumps, including active TCP and UDP connections, listening sockets, and the associated processes that own them. It works by scanning kernel data structures such as `_TCPT_OBJECT` and `_UDP_OBJECT` to provide a snapshot of network activity at the time of capture, which is critical for identifying malicious connections or unauthorized services.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✓
Network connections and listening sockets with associated processes
Why this is correct
This is correct because Volatility's netscan plugin specifically scans physical memory for Windows network structures, including TCP endpoints, TCP listeners, UDP endpoints, and UDP listeners. It pairs each socket with its owning process ID (PID) by traversing the _TCP_ENDPOINT, _TCP_LISTENER, and _UDP_ENDPOINT kernel structures. Thus it directly reveals active network connections and listening sockets along with the processes bound to them, which is the intended forensic artifact for network-related memory analysis.
✗
Open files and handles for each process
Why it's wrong here
This is incorrect because enumerating open files and handles for each process is the function of Volatility's handles plugin, which walks the Object Manager's handle table to list all object references (files, registry keys, mutexes, etc.) held by each process. The netscan plugin does not traverse Object Manager handle tables; it targets network-specific kernel objects. While a network socket may appear as a handle in a process, netscan's purpose is not to enumerate handles but to reconstruct socket and connection state directly from network structures.
✗
List of all running processes and their parent processes
Why it's wrong here
This is incorrect because listing all running processes and their parent relationships is performed by pslist or pstree plugins, which walk the doubly linked list of _EPROCESS structures (or use the parent PID in each _EPROCESS) to show process genealogy. Netscan, in contrast, focuses on the network layer by locating socket objects and their owning processes, not by enumerating process structures. Such process enumeration is a separate step in memory forensics and does not provide the kind of port and connection data that netscan extracts.
✗
The contents of the Windows firewall rules
Why it's wrong here
This is incorrect because netscan does not read or retrieve Windows Firewall policy rules. Firewall rules are stored in the registry under security settings and are not embedded in the network endpoint structures that netscan parses; extracting them would require a different plugin (e.g., printkey or a dedicated firewall-rule parser). The plugin's scope is limited to runtime network artifacts—sockets and connections—rather than configuration state like inbound/outbound filtering rules.
