Architecture, Design, and Implementation of MFA for an OT Environment

I developed and implemented MFA within the OT environment to bolster security measures and fortify the overall security stance. As part of this initiative, I built the RSA platform and seamlessly integrated it with AD for user identification. Also, I deployed RADIUS servers and clients to support various endpoint systems such as Palo Alto Captive Portal, Windows, and more.

To streamline user access to the OT environment, I integrated the MFA system with the Palo Alto Captive Portal, serving as a gateway. This portal now requests users to input their username and passcode, and upon a successful authentication process, grants them access to a terminal system for the industrial control system (ICS) through the Remote Desktop Protocol (RDP).

Moreover, I meticulously devised disaster recovery protocols and break-glass solutions for the MFA implementation, ensuring the system remains resilient and can effectively handle unforeseen scenarios.
