Which scan type is referred to as Windows Scan?

• A. -sO
• B. -sW
• C. -sR
• D. -sS

Answer: (B)

The Windows Scan is the TCP window size based probe in Nmap, invoked with the switch that specifically calls out this technique. It doesn’t rely on the usual flags in the response like a SYN-ACK or RST; instead, it analyzes the TCP receive window reported by the target to infer whether a port is open. The approach gained its “Windows Scan” name because the window behavior it leverages is tied to how Windows TCP/IP stacks handle the window, making this method distinctive from other scan types. So, the scan type referred to as Windows Scan corresponds to the Windows window-based probe switch.
