Energy, power and utilities — OT security and critical-infrastructure compliance

Applicable regulations

• CEA Cyber Security in Power Sector Guidelines for the power ecosystem
• NCIIPC expectations for Critical Information Infrastructure (CII)
• CERT-In directions (incident reporting, logging, empanelled testing)
• IEC 62443 for industrial control systems; ISO 27001 for enterprise IT

Common cybersecurity risks

• IT/OT convergence exposing grid and plant control networks
• Ransomware or sabotage disrupting generation, transmission or distribution
• Legacy SCADA, RTU and PLC systems that cannot be patched or monitored
• Remote-access and vendor compromise into control environments
• Incident-reporting and recovery gaps against CERT-In and sector expectations

Audit findings we typically see

• No segmentation between corporate IT and OT control networks
• Unmanaged remote access to SCADA and substation automation
• Incomplete CII asset inventory and data-flow mapping
• Untested backup and recovery for control-critical systems
• No OT-aware incident response or CERT-In/NCIIPC reporting process

Services required

• OT/ICS security assessment
• VAPT across enterprise and control networks
• Security architecture review (IT/OT segmentation)
• ISO 27001 ISMS
• CERT-In empanelled VAPT

Our engagement approach

• Discovery. Inventory IT and OT assets, control data flows and vendor access; confirm CEA, NCIIPC and CERT-In obligations that apply.
• Assessment. OT-safe vulnerability assessment, segmentation review and control-gap testing against IEC 62443 themes and ISO 27001.
• Remediation. A prioritised roadmap for segmentation, remote-access hardening and recovery testing, sized for 24x7 supply constraints.
• Assurance. Retest, audit-grade reporting and a board/regulator-ready risk summary.

Expected evidence

• CII and OT asset inventory with network diagrams
• Segmentation and remote-access test results
• Backup and recovery test evidence for control-critical systems
• Incident-response and CERT-In/NCIIPC reporting procedure

Deliverables

• IT/OT gap assessment mapped to CEA guidelines and IEC 62443 themes
• Segmentation and architecture recommendations
• OT-safe VAPT reports with closure evidence
• Supply-safe remediation roadmap
