Explanation:
Most communications are vulnerable to some type of wiretapping or eavesdropping.
It can usually be done undetected and is referred to as a passive attack versus an active attack. -Shon Harris All-in-one CISSP Certification Guide pg 649
“(I) An attack that intercepts and accesses data and other information contained in a flow in a
communication system. (C) Although the term originally referred to making a mechanical
connection to an electrical conductor that links two nodes, it is now used to refer to reading
information from any sort of medium used for a link or even directly from a node, such as gateway
or subnetwork switch. (C) “Active wiretapping” attempts to alter the data or otherwise affect the
flow; “passive wiretapping” only attempts to observe the flow and gain knowledge of information it
contains. (See: active attack, end-to-end encryption, passive attack.)”
