Level 2: Network Infrastructure (cross-protocol boundary crossing)
IEC 60870-5-104 power grid protocol exposure enabling unauthorized SCADA commands has increased. An adversary leveraging this exposure can manipulate substation switching operations, alter protection parameters, and disrupt grid synchronization. This represents a 2900% increase over the 30-day rolling mean (1 vs 0.03 items, σ=0.18).

MZ Automation lib60870 | Intel Pattern | Source: CISA ICS Advisories, Severity: critical |
| Priority | Phase | Action |
|---|---|---|
| Immediate (0-48 hours): | Audit all network-facing interfaces for iec 104 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 |
