The breach began with a single compromised password. One login, reused across systems, was all it took. Multi-Factor Authentication (MFA) stops that chain reaction. Zero Trust Access Control ensures it never starts. Together, they turn every identity check into a hardened gate, every request into a verified transaction.
MFA in a Zero Trust framework is not optional. It is the baseline. A valid username and password are no longer enough. Every login must pass multiple layers: something you know, something you have, something you are. SMS codes, authenticator apps, security keys, and biometric scans each reduce the surface for attack. No single factor is trusted standing alone.
Zero Trust Access Control assumes the network is hostile, even inside the firewall. It removes implicit trust from every endpoint, device, and user. Each action, from API calls to database queries, is authenticated and authorized in real time. Access policies are dynamic. They adapt to context: device health, geolocation, time of request, and risk score.
