Dear An ATTACK can take place on any of the communications link. For an active attack, the attacker needs to gain physical control of a portion of the link and be able to insert and capture transmissions ( medium could be telephone twisted pair, coaxial cable, or optical fiber). For a passive attack, the attacker merely needs to be able to observe transmissions (may be inductive taps).
