Cyber Security: New American National Standard Provides Guidance for Industrial Automation and Control Systems

New York, Jan 16, 2008

From computer viruses and hackers to phishing schemes and stolen credit card numbers, the safety and security of the electronic environment is of critical importance. Many security guidelines exist for personal computers, networked systems, and other information and communication technologies (ICT), but a new American National Standard developed by ISA – a member of the American National Standards Institute (ANSI) and accredited standards developer – is the first to apply these issues to industrial automation and control systems (IACSs).

Recent developments in IACS technology have made these computer environments increasingly vulnerable to cyber attack. Frequently developed through joint ventures and outsourcing, IACS equipment is often connected to networked computer systems, further increasing the risk of a disruptive network intrusion.

The new standard, ANSI/ISA-99.00.01-2007, Security for Industrial Automation and Control Systems Part 1: Terminology, Concepts, and Models, begins an exploration of the numerous electronic security technologies and countermeasures potentially available to the IACS environment.

Focusing on key concepts, terminology, and models, the standard serves as a foundation for additional standards currently in development, including ISA99.00.02 – Part 2: Establishing an Industrial Automation and Control System Security Program and ISA99.00.03 – Part 3: Operating an Industrial Automation and Control System Security Program.

In addition, ISA has published an updated technical report on IACS cyber security. Providing an assessment of currently available tools, countermeasures, and technologies, ANSI/ISA-TR99.00.01-2007, Security Technologies for Industrial Automation and Control Systems, applies to existing and new IACSs for multiple industries and infrastructures.
