== Executive Summary ==


Supply chains have become a strategic focus area for utilities and critical infrastructure operators. Globally sourced hardware, software, and connected technologies introduce cybersecurity, operational, and geopolitical risks that can impact reliability, resilience, and business operations.
Operational Technology (OT) Asset Visibility platforms have become foundational capabilities for utility cybersecurity, operational resilience, and asset management programs. As industrial environments become more connected, organizations require accurate visibility into assets, communications, software, and network behavior across generation, transmission, distribution, and critical infrastructure environments.


At the same time, utilities are investing in advanced visibility and decision-support capabilities including Artificial Intelligence (AI), Supply Chain Control Towers, Digital Twins, and supplier-risk monitoring. These capabilities help organizations improve situational awareness, identify disruptions earlier, and strengthen long-term resilience.
Modern OT visibility platforms provide continuous asset discovery, protocol awareness, behavioral analysis, and integration with security operations tools. These capabilities help organizations improve situational awareness, reduce cybersecurity risk, and support operational decision-making.

== Key Supply Chain Risks ==
== Industry Context ==


=== Technology & Asset Assurance ===
Industrial control systems were historically designed for reliability and availability rather than cybersecurity. As utilities continue integrating modern technologies, remote connectivity, cloud services, distributed energy resources, and vendor support services, maintaining visibility across OT environments has become increasingly important.


Recent industry assessments have highlighted the importance of understanding communications protocols, data flows, vendor connectivity, and remote access capabilities associated with modern energy technologies.<ref>[https://msites.epri.com/spn/research/112046/security-design-architecture-review%3A-solar-inverters EPRI Security Design Architecture Review: Solar Inverters (3002029720)]</ref>
Unlike traditional IT environments, OT networks often contain specialized devices, proprietary protocols, and legacy equipment that may be difficult to inventory and monitor through conventional security tools.


Examples include:
Asset visibility platforms provide a continuously updated view of industrial environments without actively interacting with critical assets, helping organizations improve awareness while minimizing operational risk.


* Cellular communications modules
----
* Wi-Fi connectivity
* Bluetooth interfaces
* Vendor remote-access capabilities
* Undocumented communications pathways


'''Why It Matters'''
== Core Capabilities ==


For utilities, uncertainty surrounding deployed technologies can complicate asset management, cybersecurity monitoring, incident response, and overall operational awareness. The challenge is often less about a specific technology and more about understanding exactly what has been deployed and how it communicates.
=== Asset Discovery ===


=== Software Supply Chain Risk ===
Asset visibility platforms use passive monitoring techniques to identify and inventory devices communicating across operational networks.


Modern utility operations depend on software vendors, cloud providers, embedded firmware, open-source components, and third-party integrators.
Commonly discovered assets include:


A compromise of a trusted software supplier can potentially affect multiple organizations simultaneously. As software ecosystems grow increasingly complex, visibility into software dependencies becomes more important.
* Programmable Logic Controllers (PLCs)
* Human Machine Interfaces (HMIs)
* Distributed Control Systems (DCS)
* Supervisory Control and Data Acquisition (SCADA) systems
* Intelligent Electronic Devices (IEDs)
* Workstations and servers
* Network infrastructure


EPRI's Technical Assessment Methodology (TAM) emphasizes evaluating attack surfaces, identifying security gaps, and validating security controls throughout technology deployments. <ref>[https://www.epri.com/research/programs/112046/results/3002021184 EPRI Technical Assessment Methodology (3002021184)]</ref> <ref>[https://www.epri.com/research/programs/112046/results/3002017149 EPRI Technical Assessment Methodology (3002017149)]</ref>
'''Why It Matters'''
 
=== Geopolitical & Supplier Risk ===
 
Global supply chains remain vulnerable to geopolitical developments, manufacturing concentration, transportation constraints, and evolving trade regulations.
 
Examples include:
 
* Trade restrictions and tariffs
* Export controls
* Semiconductor shortages
* Critical mineral dependencies
* Transportation disruptions
 
These events can affect equipment availability, increase lead times, and delay infrastructure investments across the utility sector.

== Supply Chain Cybersecurity ==
Organizations cannot effectively secure assets they do not know exist. Comprehensive inventories provide the foundation for cybersecurity, compliance, vulnerability management, and operational planning.


As utilities continue their digital transformation efforts, cybersecurity considerations increasingly extend beyond organizational boundaries and into supplier ecosystems.
=== Asset Context & Intelligence ===


Industry supply chain security programs focus on understanding software integrity, vendor access, communications pathways, and architectural risks before technologies are deployed.<ref>[https://msites.epri.com/spn/research/112046/security-design-architecture-review%3A-solar-inverters EPRI Security Design Architecture Review: Solar Inverters (3002029720)]</ref>
Beyond inventory management, modern platforms correlate multiple data sources to build operational context around assets and communications.


EPRI's Defensible Network Architectures guidance provides criteria for securely deploying operational technologies and reducing exposure to unauthorized access pathways.<ref>[https://www.epri.com/research/products/000000003002027430 EPRI Defensible Network Architectures: Criteria for Secure OT Deployment in Power Systems (3002027430)]</ref>
This may include:


'''Leading Practices'''
* Industrial protocols
* Communications patterns
* Device relationships
* Software and firmware information
* Asset criticality
* Network dependencies


* Supplier cybersecurity assessments
By understanding how assets communicate and interact, organizations can better prioritize cybersecurity risks and operational dependencies.
* Software Bills of Materials (SBOMs)
* Hardware Bills of Materials (HBOMs)
* Vendor access reviews
* Multi-Factor Authentication (MFA)
* Network segmentation
* Continuous supplier monitoring


----
=== Behavioral Visibility ===


== Artificial Intelligence in Supply Chains ==
Many OT visibility platforms establish behavioral baselines by observing normal communications over time.


[[File:Audit AI Agent.jpg|thumb|right|450px|AI-Enabled Supply Chain Analytics]]
This allows organizations to identify:


Artificial Intelligence is helping organizations move beyond reactive supply chain management by improving forecasting, disruption analysis, inventory planning, and supplier-risk identification.
* Unexpected communications
