Authentication

Authentication acts like the multilayered checkpoints at a major airport, verifying who you are before you board. Passwords remain the familiar ID badge that most users present, but they are vulnerable to brute-force attempts and credential stuffing as if attackers had an army of forged passes. Multi-Factor Authentication supercharges that checkpoint by demanding a badge, a fingerprint or token (what you are or have), making it exponentially harder for intruders to slip through. Centralized identity platforms like LDAP, Active Directory, and OAuth function as the airport’s control tower, coordinating single sign-on across systems, but exactly like the tower, they need rock solid defenses and constant monitoring to avoid a system wide shutdown.
