1) Eavesdropping: Eavesdropping is the unauthorized
real-time interception of a private communication through
secretly listening, monitoring, or examining their conversation
without their consent or knowledge. Through passive
eavesdropping, adversaries apparently eliminate their presence
in the network and make such attacks difficult to detect. The
kind of attack aims to violate the confidentiality of the
communications by intercepting the network and sniffing to
the routing packets.
