Level 2: Network Infrastructure (cross-protocol boundary crossing)
PLC/RTU remote access exposure enabling unauthorized field device manipulation has increased. An adversary leveraging this exposure can manipulate field device configurations, override safety interlocks, and trigger unauthorized physical actions. This represents a 900% increase over the 30-day rolling mean (1 vs 0.1 items, σ=0.40).

Synectics secures NPSA CAPSS certification for Synergy security platform, strengthens critical infrastructure security | Intel Pattern | Source: Industrial Cyber, Severity: critical |
| Priority | Phase | Action |
|---|---|---|
| Immediate (0-48 hours): | Audit all network-facing interfaces for plc rtu 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 |
