A security tester needs to verify if a remote port that relies on a handshake is open. Which technique is the best for confirming that the service is active?
A sequence that sends a partial request and interprets an unreachable message as a closed port
An approach that completes all steps in the connection sequence to confirm the service is active
A broadcast-based method that checks for responses from all devices
A minimal approach that avoids handshake signals and times out to identify open ports
Completing all aspects of the connection sequence verifies that the service truly accepts inbound requests. A partial request that waits for an unreachable message does not confirm whether the service actually accepts the connection. Broadcast queries locate responding devices but do not validate handshake-based ports. A minimal approach that times out can identify suspects but does not confirm a handshake.
