Man in the Middle
In plain terms
An attacker secretly intercepting communication between two parties.
Going deeper
In a man-in-the-middle attack, an adversary positions between two parties to eavesdrop or alter their traffic while they believe it's private. Encryption defends against it.
Under the hood
TLS and certificate validation prevent it; risks rise on untrusted networks like open Wi-Fi.
Examples
Wi-Fi interception, SSL stripping, packet sniffing, rogue access points.
Think of it like...
Like a courier secretly reading and altering letters before passing them along.
