NIST 800-82 -Industrial Control System Guidelines

NIST 800-82 is a publication from the National Institute of Standards and Technology (NIST) that provides guidelines for industrial control system (ICS) security. It serves as a reference for organizations that operate or manage ICS, such as those in the energy, water, and transportation industries.

ICS refers to the systems and equipment used to control, monitor, and operate physical processes, such as manufacturing, power generation, and transportation. NIST 800-82 provides guidance on how to secure these systems from threats such as cyber attacks, unauthorized access, and natural disasters.

The guidelines in NIST 800-82 are divided into three main sections: security management, security design, and security assessment.

Security Management

Security management covers topics such as risk management, incident response, and security policy. The guidelines recommend that organizations establish a risk management program, develop an incident response plan, and develop a security policy that outlines their approach to ICS security.

Security Design

Security design covers topics such as access control, network security, and system architecture. The guidelines recommend that organizations implement robust access control measures, such as user authentication and authorization, and secure their networks using technologies such as firewalls and intrusion detection systems. They also recommend that organizations follow a layered approach to system architecture, where different security measures are applied at different levels of the system.

Security assessment

Security assessment covers topics such as vulnerability assessment, penetration testing, and security auditing. The guidelines recommend that organizations regularly assess their ICS for vulnerabilities, and test their systems for security weaknesses using penetration testing. They also recommend that organizations conduct security audits to verify that their security measures are effective.

In conclusion, NIST 800-82 provides essential guidance for organizations that operate or manage ICS. By following the guidelines, organizations can improve the security of their systems and reduce the risk of cyber attacks, unauthorized access, and natural disasters.

How it is related to IEC 62443

NIST 800-82 is related to IEC 62443, which is an international standard for industrial control system security. IEC 62443 provides a comprehensive framework for securing industrial control systems and is widely recognized as the leading standard in this area.

NIST 800-82 is based on the concepts and best practices outlined in IEC 62443 and provides more specific guidelines and recommendations for organizations operating or managing ICS in the United States. Both NIST 800-82 and IEC 62443 aim to improve the security of ICS and reduce the risk of cyber attacks and other security incidents.

In summary, NIST 800-82 is a national interpretation of the international standard IEC 62443, providing organizations with specific guidance on how to implement the best practices outlined in IEC 62443 in their ICS security programs.
