(NIST) promotes the U.S. economy and public welfare by providing technical leadership for the nation's measurement and standards infrastructure. ITL develops tests, test methods, reference data, proof of concept implementations, and technical analysis to advance the development and productive use of information technology. ITL's responsibilities include the(More)
This document provides guidance on how to secure Industrial Control Systems (ICS), including Supervisory Control and Data Acquisition (SCADA) systems, Distributed Control Systems (DCS), and other control system configurations such as Programmable Logic Controllers (PLC), while addressing their unique performance, reliability, and safety requirements. The(More)
The National Institute of Standards and Technology (NIST) is working to improve the information technology (IT) security of networked digital control systems used in industrial applications. This effort is being carried out through the Process Control Security Requirements Forum (PCSRF), an industry group organized under the National Information Assurance(More)
The United States Government as well as the industrial controls sector has come to realize that securing computer systems that control industrial production and distribution is vital to the protection of key components of its critical infrastructure and the health of the associated economies at risk. Current systems are designed first and foremost to meet(More)

Since the advent of control systems, SCADA has played an important role in the field of automation. SCADA systems offer a means of controlling remotely located devices in an industrial process. Supervisory control can be combined with data acquisition wherein the data is obtained from the devices and it is processed further according to the user's(More)
control systems are touted by the sellers as standards-based and comprehensive. Buyer beware, most of these claims are highly exaggerated. Only the International Society for Automation (ISA) is developing standards that are comprehensive in the sense that cyber security requirements control systems are defined as an extension of the security policies for(More)
A test suite for a key interface within a dimensional measuring system (coordinate measuring machine or CMM) is presented. The test suite consists of test procedures, test definitions, and various testing utilities. A real-time, distributed test utilizing the test suite has been performed and is described. Keywords— conformance test, coordinate measuring(More)
Cyber-Physical Systems (CPS) are systems with seamless integration of physical, computational and networking components. These systems can potentially have an impact on the physical components, hence it is critical to safeguard them against a wide range of attacks. In this paper, it is argued that an effective approach to achieve this goal is to(More)
Industrial control systems (ICS) are composed of sensors, actuators, control processing units, and communication devices all interconnected to provide monitoring and control capabilities. Due to the integral role of the networking infrastructure, such systems are vulnerable to cyber attacks. Indepth consideration of security and resilience and their effects(More)
