NIST 800-82 R2/R3: A Practical Guide for OT Security Professionals – Security Boulevard>
– wordpress-plugin
NIST 800-82, Revision 2 (R2) and Revision 3 (R3) is a comprehensive guide for OT security professionals.
In both the R2 and R3 documents, NIST provides detailed security engineering and management practices for protecting OT systems.
At a high-level, the R2 and R3 documents apply adefense-in-depth approach for protecting OT systems, emphasizing the value of layered controls and systems secured by multiple layers of defense.
This approach helps protect against new and novel threats that may not be foreseeable at the time the system is designed.
NIST 800-82 R2 and R3 offer guidance on:
1.
Networking and communication architectures.
2.
Segmentation, virtualization, authentication, and authorization techniques to protect OT systems.
3.
Communication protocols, including authentication and encryption protocols.
4.
Monitoring activities and incident response procedures.
5.
Creating operational safety procedures to anticipate and mitigate risks.
6.
Developing resilient networks that are able to recover quickly from incidents.
7.
Implementing operational technologies that can self-heal and self-correct from malicious attacks.
8.
Establishing comprehensive physical access controls and security policies.
Finally, NIST 800-82 R2 and R3 offer best practices and guidance for assessing and addressing cybersecurity risks for existing OT systems.
The guidance provided helps OT professionals understand and mitigate risks, and identify and implement security controls for all areas of the OT ecosystem.
