NACIO Non-Obtrusive Authentication of Critical Infrastructure Operators

Free registration required

Executive Summary

NACIO addresses a large security hole that exists in many critical infrastructure control centers. Because of operational constraints, operators are not authenticated to the workstations that control critical infrastructure. Anyone with physical access to the workstation has the ability to control these critical systems. NACIO provides mechanisms to detect and track critical commands and tie them to the issuing operator in a transparent manner. Traditional authentication mechanisms are inadequate for many workstations that control real-time process control systems. Loss of access to these workstations can result in catastrophic events including the loss of life.
