Question

The scanning algorithm in a port scanning tool is designed to continue sending SYN packets to targets rather than actively listening for a response from each one before proceeding. How does this design decision impact its capabilities?

Options

AThe scan is more thorough than a regular port scan
BThe time it takes to scan is reduced
CThe source of the scan is obscured
DThe SYN/ACK responses can be received by multiple hosts

Explanation

Masscan is an example of a scan tool that is very fast, due to the approach that the scan tool separates the sending of SYN packets from waiting to receive the SYN/ACK packet(s). This separation allows the scan to initiate SYN packets to their target hosts very fast, not needing to await a response for each SYN packet sent before proceeding.
