The ISA99 Committee addresses industrial automation and control systems whose compromise could result in any or all of the following situations:
- endangerment of public or employee safety
- negative impact on performance in the areas of health and environment
- loss of public confidence
- violation of regulatory requirements
- loss of proprietary or confidential information
- economic loss
- impact on national security
The concept of industrial automation and control systems electronic security is applied in the broadest possible sense, encompassing all types of plants, facilities, and systems in all industries. Manufacturing and control systems include, but are not limited to:
- hardware and software systems such as DCS, PLC, SCADA, networked electronic sensing, and monitoring and diagnostic systems
- associated internal, human, network, or machine interfaces used to provide control, safety, and manufacturing operations functionality to continuous, batch, discrete, and other processes.
Physical security is an important component in the overall integrity of any control system environment, but it is not specifically addressed in this series of documents.
