What is NIST

NIST stands for The National Institute of Standards and Technology.

It is part of U.S. department of commerce and was founded in 1901.

NIST is one of the nation's oldest physical science laboratories.

Congress established the agency to remove a major challenge to U.S. industrial competitiveness at the -a second-rate measurement infrastructure that lagged behind the capabilities of the United Kingdom, Germany, and other economic rivals.

What is ICS

Supervisory control and data acquisition (SCADA) systems - are generally used to control dispersed assets using centralized data acquisition and supervisory control.

Distributed control systems (DCS) - are generally used to control production systems within a local area such as a factory using supervisory and regulatory control.

Programmable Logic Controllers (PLC) - are generally used for discrete control for specific applications and generally provide regulatory control.

ICS are used in industries such as electric, water and wastewater, oil and natural gas, transportation, chal, pharmaceutical, pulp and paper, food and beverage, and discrete manufacturing (e.g., automotive, aerospace, and durable goods.)
