NAICS Code is a standardized system used by governments in North America to classify businesses and industries based on their primary economic activities. This six-digit code facilitates the collection, analysis, and publication of statistical data related to the business economy, enabling policy makers, businesses, and researchers to understand economic conditions, trends, and patterns.
Understanding NAICS Code in the Context of OT/IT Cybersecurity
In the realm of Operational Technology (OT) and Information Technology (IT) cybersecurity, the NAICS code plays a crucial role in identifying and classifying the types of industries that require specific security measures. Each industrial sector faces unique cybersecurity challenges; for instance, manufacturing plants, power utilities, and healthcare systems each have distinct vulnerabilities and compliance requirements. By categorizing businesses into specific NAICS codes, cybersecurity professionals can tailor their security strategies to the particular needs and threats associated with each industry.
Importance in Industrial, Manufacturing & Critical Environments
For industrial and manufacturing environments, understanding your business's NAICS code is critical for a few reasons:
-
Regulatory Compliance: Various cybersecurity frameworks and standards, such as NIST SP 800-171, CMMC, and NIS2, often require organizations to identify their industry classification to determine applicable controls and compliance mandates. For example, a manufacturing company classified under a specific NAICS code might be subject to different regulations compared to a service-based business.
-
Risk Management: Different industries face different types of cyber threats. The NAICS code helps organizations understand common vulnerabilities and threat vectors within their sector, enabling them to implement more effective risk management and mitigation strategies.
-
Benchmarking and Best Practices: By comparing with other businesses within the same NAICS classification, companies can benchmark their cybersecurity practices and performance. This comparison is invaluable for identifying gaps and adopting industry best practices to improve their security posture.
-
Resource Allocation: Knowing the NAICS code helps in prioritizing cybersecurity resources and investments. Industries with high-risk profiles, such as critical infrastructure, may require more robust security controls and monitoring efforts.
Reference to Standards
NIST SP 800-171
NIST SP 800-171 outlines the protection of Controlled Unclassified Information (CUI) in non-federal systems. Understanding your NAICS code can help determine if your organization handles CUI and, consequently, which security requirements are relevant.
CMMC
The Cybersecurity Maturity Model Certification (CMMC) requires defense contractors to adhere to specific cybersecurity practices. The industry classification via NAICS codes aids in identifying applicable CMMC levels and practices for organizations involved in the defense supply chain.
NIS2 Directive
The NIS2 Directive applies to essential services, many of which are categorized under specific NAICS codes. This classification helps determine the criticality of services provided and the corresponding security obligations.
IEC 62443
The IEC 62443 series of standards focus on industrial automation and control systems security. Identifying your industry through the NAICS code can guide compliance efforts with relevant parts of the IEC 62443 standards.
In Practice
Consider a manufacturing company that produces automotive parts. This company would have a specific NAICS code that categorizes it within the broader manufacturing sector. By recognizing this classification, the company can better understand the common cybersecurity threats in the automotive supply chain, such as intellectual property theft or operational disruptions. Consequently, the company can implement tailored security measures, align with relevant standards like CMMC if they are part of the defense supply chain, and ensure compliance with regional directives like NIS2.
