Quizplus · Accepted Answer

A port scanner can identify active computers on a network by scanning for open ports and their associated services. This is a commonly used technique in network reconnaissance to map out target systems. A packet sniffer captures packets on a network, but it may not necessarily provide information on active computers. Trap and trace is a legal process used to collect information on network traffic for law enforcement purposes. A honey pot is a decoy system used to lure attackers away from actual systems.
