An attacker monitoring network traffic between nodes of a public or
						multicast network. The attacker need not be able to prevent reception or
						change content but must simply be able to observe and read the traffic. The
						attacker might precipitate or indirectly influence the content of the
						observed transaction, but the attacker is never the intended recipient of
						the information. This differs from other sniffing attacks in that it is over
						a public network rather via some other communications channel, such as
						radio.
