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