Cyber Resilience Briefing — March 24, 2025
Critical infrastructure operators face blended IT/OT intrusions; Zeph Tech aligns detection modernization with CISA Cross-Sector Cybersecurity Performance Goals and NERC CIP-007-6.
Executive briefing: Converged IT and OT operations continue to attract espionage and disruption campaigns, making visibility across both domains non-negotiable. Zeph Tech is unifying telemetry, incident playbooks, and board-level metrics so utilities and manufacturers can prove alignment with CISA’s Cross-Sector Cybersecurity Performance Goals (CPGs) and NERC CIP-007-6.
Key industry signals
- Nation-state living-off-the-land tradecraft. The joint advisory on PRC state-sponsored Volt Typhoon operations documents how adversaries blend native admin tools, underscoring the need for correlated IT/OT detections.
- CPG adoption momentum. CISA’s CPG 2.0 provides sector-agnostic baselines for vulnerability management, logging, and incident response—now referenced in multiple state resilience grants.
- OT incident metrics rising. Dragos’ 2023 OT Cybersecurity Year in Review logged a 35% increase in publicly reported ransomware activity against industrial firms, emphasizing defensive urgency.
Control alignment
- CISA CPGs. Map SOC and plant engineering detections to CPG functions covering visibility, vulnerability reduction, and incident response.
- NERC CIP-007-6. Document how patch management, logging, and malicious code prevention controls operate for BES Cyber Systems and supporting components.
Detection and response priorities
- Alert on remote sessions that traverse from enterprise networks into control zones without approved change tickets or maintenance windows.
- Correlate engineering workstation and historian logs with OT sensor anomalies so analysts can reconstruct lateral movement paths quickly.
Enablement moves
- Schedule joint SOC, NOC, and plant-tabletop drills that rehearse VPN credential theft, engineering workstation compromise, and recovery communications.
- Publish executive dashboards that benchmark CPG coverage, CIP-007 compliance, and mean time to detect hybrid intrusions.
- Pair this detection modernization with the OT ransomware containment playbook so response teams align telemetry with recovery runbooks.
