Common Use Cases

NERC CIP Compliance Automation

Automate NERC CIP compliance with continuous monitoring of critical cyber assets, real-time security event logging, and complete audit trails.

Challenge: NERC CIP requires continuous monitoring of critical cyber assets but manual compliance processes are resource-intensive and often miss critical events. NERC CIP requires continuous monitoring of critical cyber assets, real-time security event logging, and comprehensive audit trails with automated incident reporting for regulatory compliance. Traditional approaches struggle with the complexity of industrial control systems and the stringent documentation requirements for regulatory audits.

  • Compliance Documentation: Automated generation of NERC CIP compliance reports with audit-ready evidence and regulatory submission workflows
  • Change Management Integration: Integration with change management processes to ensure all modifications to critical cyber assets are properly documented and approved

Implementation Process:

  1. Week 1: Deploy monitoring infrastructure and establish critical cyber asset inventory and baseline configurations
  2. Week 2: Implement security event correlation and NERC CIP-specific threat detection rules
  3. Week 3: Configure automated incident reporting and compliance documentation workflows
  4. Week 4: Conduct compliance validation and establish ongoing regulatory reporting procedures

Measurable Outcomes:

  • 85% reduction in NERC CIP compliance overhead through automated monitoring and reporting
  • Real-time critical cyber asset monitoring with immediate security event detection
  • Automated regulatory incident reporting with NERC CIP-compliant documentation and evidence
  • Complete audit trails for regulatory examination and compliance validation

NERC CIP Audit Prep Checklist

Teams can use this short, practical checklist before each audit window. For a utility example of applying these practices, see the EnerGeo case study.

| Pre‑audit task | | --- | | Validate current list of critical cyber assets and owners. | | Confirm incident reporting workflow, contacts, and time thresholds. | | Review last quarter’s change tickets mapped to CIP controls. | | Spot‑check evidence packages (screenshots, logs, and sign‑offs). | | Verify retention settings and chain‑of‑custody procedures. |

OT Network Security Monitoring

Security monitoring of operational technology networks with protocol-aware threat detection.

Challenge: Traditional IT security tools cannot effectively monitor OT networks due to different protocols, availability requirements, and operational constraints.

LogZilla Solution: OT-specific security monitoring with industrial protocol analysis, non-intrusive monitoring, and operational continuity protection.

Nation-State Attack Detection

Advanced threat detection specifically designed to identify sophisticated attacks targeting critical infrastructure.

Challenge: Critical infrastructure faces sophisticated nation-state attacks that traditional security tools cannot detect or respond to effectively.

LogZilla Solution: Advanced behavioral analytics and threat detection specifically tuned for critical infrastructure attack patterns including living-off-the-land techniques.

Industrial Process Anomaly Detection

Monitor industrial processes for both cybersecurity threats and operational anomalies that could indicate system compromise.

Challenge: Cyber attacks on critical infrastructure often manifest as operational anomalies, but traditional security tools cannot correlate operational and security data.

LogZilla Solution: Integrated operational and security monitoring with machine learning-based anomaly detection for both cybersecurity and process safety threats.

Critical Infrastructure Challenges

Critical infrastructure organizations face unique cybersecurity challenges that require specialized approaches to operational technology (OT) security and regulatory compliance. Traditional IT security solutions often cannot address the specific requirements of industrial control systems and critical infrastructure environments.

OT/IT Convergence Security Complexity

The convergence of operational technology and information technology creates new attack vectors and security challenges that traditional security tools cannot address. OT/IT convergence creates new attack vectors requiring specialized monitoring that understands industrial protocols while maintaining operational continuity. This convergence results in:

  • Protocol Complexity: Industrial protocols like Modbus, DNP3, and IEC 61850 require specialized monitoring approaches that traditional IT security tools cannot provide
  • Availability Requirements: Critical infrastructure systems require 99.99% uptime, making traditional security approaches that could impact operations unsuitable
  • Legacy System Integration: Aging industrial control systems lack modern security features and require non-intrusive monitoring approaches
  • Real-Time Constraints: Industrial processes operate in real-time with microsecond timing requirements that security monitoring cannot disrupt attack vectors and monitoring challenges, as traditional IT security tools cannot effectively monitor OT environments due to different protocols, availability requirements, and operational constraints.

Nation-State and Advanced Persistent Threats

Critical infrastructure organizations are primary targets for nation-state actors and advanced persistent threat (APT) groups. These sophisticated attacks often use living-off-the-land techniques, zero-day exploits, and long-term persistence strategies that require advanced detection capabilities beyond traditional security monitoring.

Critical infrastructure faces nation-state attacks that target industrial control systems and operational technology with sophisticated techniques.

NERC CIP and Regulatory Compliance

Electric utilities and other critical infrastructure organizations must comply with NERC CIP requirements for cybersecurity. These regulations require continuous monitoring, incident reporting, and complete audit trails for critical cyber assets. Manual compliance processes are resource-intensive and often incomplete.

Operational Continuity Requirements

Critical infrastructure systems cannot tolerate security monitoring that impacts operational availability or performance. Security solutions must provide full visibility while maintaining zero impact on critical operational systems and processes.
