Architect’s Guide: ICS Security Using TNC Technology

Architects Guide

Industrial Control Systems (ICSs) are increasingly being connected to networks and exposed to viruses, malware, and attacks that affect other network-connected systems.

As a result, many standards organizations including the International Society of Automation (ISA), the International Electrotechnical Commission (IEC), and the Trusted Computing Group (TCG) [as well as the Internet Engineering Task Force (IETF), The Open Group and others] are developing standards-based approaches for increased control system security.

This Architect’s Guide shows information technology (IT) and control systems executives and architects how to implement a standards-based, interoperable approach to ICS security as specified in ISA 99 (now IEC 62443) and ISA 100.15.
