Selected Answer: B
The correct answer is: B. port scanning Explanation: A port scanning attack is characterized by sending packets (often a single SYN packet) to multiple ports on a target machine to determine which ports are open, closed, or filtered. This behavior aligns with the scenario described, where a single SYN packet is sent to each port. Why not D. SYN flood A SYN flood attack involves sending numerous SYN packets to a specific port to overwhelm the target, which is different from the described behavior of targeting multiple ports with single packets.
