== Assessment Overview ==
== Platform Overview ==
 
Assessment activities focused on understanding communications pathways, device configurations, software services, hardware components, and external connectivity associated with inverter deployments.<ref>[https://msites.epri.com/spn/research/112046/security-design-architecture-review%3A-solar-inverters EPRI Security Design Architecture Review: Solar Inverters (3002029720)]</ref>
 
The objective was not only to identify vulnerabilities, but also to validate assumptions regarding connectivity, architecture, vendor access, and operational behavior.<ref>[https://www.epri.com/research/products/000000003002012752 EPRI Technical Assessment Methodology (3002012752)]</ref>


Findings repeatedly demonstrated the importance of independent validation throughout procurement, commissioning, and operational lifecycle activities.
Organizations commonly deploy a combination of asset visibility, threat detection, exposure management, threat intelligence, and vulnerability management platforms. While capabilities overlap, platforms often have different strengths depending on operational requirements and cybersecurity objectives.

== Key Findings ==
== Dragos ==
 
=== Undocumented Communications Capabilities ===
 
Recent EPRI assessments have highlighted the importance of understanding communications protocols, data flows, and connectivity that may not be fully understood or documented by system owners and operators.<ref>[https://msites.epri.com/spn/research/112046/security-design-architecture-review%3A-solar-inverters EPRI Security Design Architecture Review: Solar Inverters (3002029720)]</ref>
 
Examples observed during assessment activities included:
 
* Undocumented 868 MHz communications
* Undocumented 900 MHz communications
* Wireless interfaces not reflected within deployment documentation
* Unexpected communications pathways
* Communications behavior not represented in architecture diagrams
 
'''Why It Matters'''


Utilities frequently develop network architectures, monitoring strategies, and incident response plans based on expected communications behavior. Undocumented communications can create blind spots that reduce visibility and complicate operational awareness.

=== Overview ===


=== Hidden Cellular Connectivity ===
Dragos is an OT-focused cybersecurity platform designed specifically for industrial and critical infrastructure environments. The platform emphasizes asset visibility, industrial threat detection, incident response, and operational risk awareness.


Assessment activities identified embedded cellular communications capabilities within inverter systems.
=== Key Capabilities ===


Examples included:
* Comprehensive OT asset discovery and inventory
* Industrial protocol awareness
* Behavioral and anomaly-based threat detection
* Visibility into PLCs, HMIs, DCS, SCADA systems, and IEDs

=== Lifecycle Risk Extends Beyond Deployment ===
EPRI research continues to emphasize understanding communications flows, architecture dependencies, external connectivity, and operational context as essential cybersecurity capabilities.<ref>[https://msites.epri.com/spn/research/112046/security-design-architecture-review%3A-solar-inverters EPRI Security Design Architecture Review: Solar Inverters (3002029720)]</ref>


Supply chain risk does not end after procurement.
In practice:


Organizations should continuously evaluate firmware, software, communications pathways, and vendor access throughout the lifecycle of deployed technologies.<ref>[https://www.epri.com/research/programs/112046/results/3002012753 EPRI Supply Chain Assessment Research Program]</ref>
* OT-focused platforms such as Dragos provide deeper industrial visibility and threat detection.
