Level 2: Network Infrastructure (cross-protocol boundary crossing)
Supply chain compromise patterns enabling multi-vendor infiltration have increased. An adversary leveraging this exposure can compromise multiple OT vendors simultaneously, enabling widespread equipment compromise across sectors. This represents a 165% increase over the 30-day rolling mean (3 vs 1.13 items, σ=1.12).

|---|---|---|
| Immediate (0-48 hours): | Audit all network-facing interfaces for supply chain exposure Verify segmentation boundaries (Purdue model compliance) Review IDS/IPS signatures for protocol-specific detection | |
| Short-term (1-2 weeks): | Implement allow-listing for authorized protocol traffic Deploy network monitoring at OT/IT boundary points Update incident response playbooks | |
| Long-term (1-3 months): | Engage with vendor security programs for hardening guidance Implement authenticated industrial protocols where available Deploy unidirectional gateways for critical safety communications |
