Introduction
Oil & Gas Separation Plants are a critical part of India’s upstream oil and gas value chain. These facilities receive production fluids from wells and separate crude oil, natural gas, water, and other by-products before they are transported for further processing, storage, or distribution. The efficiency, reliability, and safety of these plants depend heavily on Operational Technology (OT) systems that automate and monitor complex industrial processes.
Modern separation plants utilize Industrial Control Systems (ICS), Supervisory Control and Data Acquisition (SCADA) systems, Distributed Control Systems (DCS), Programmable Logic Controllers (PLCs), Safety Instrumented Systems (SIS), Human Machine Interfaces (HMIs), Emergency Shutdown Systems (ESD), process analyzers, tank management systems, and industrial communication networks. The adoption of Industrial Internet of Things (IIoT), remote monitoring, predictive maintenance, and integration between IT and OT environments has enhanced operational efficiency while increasing cybersecurity exposure.
Cyber threats targeting industrial environments have become increasingly sophisticated. A successful attack on an oil & gas separation plant could interrupt production, compromise safety systems, affect environmental protection measures, damage critical equipment, and result in costly operational downtime. Conducting an OT Security Assessment enables organizations to identify vulnerabilities, evaluate cyber risks, strengthen industrial security controls, and improve operational resilience while maintaining safe and continuous operations.
Cyberintelsys is a CREST-accredited cybersecurity company for Vulnerability Assessment (VA) and Penetration Testing (PT), delivering industry-recognized security testing services for organizations across multiple sectors.
OT Security Standards and Regulatory Alignment
Oil & Gas Separation Plants are part of India’s critical energy infrastructure and require cybersecurity strategies specifically designed for Operational Technology environments. Industrial systems prioritize availability, safety, and reliability, making specialized security assessments essential.
Cyberintelsys conducts OT Security Assessments aligned with internationally recognized industrial cybersecurity frameworks and best practices, including:
IEC 62443 Industrial Automation and Control Systems Security

ISO/IEC 27001 security management practices where applicable
Cybersecurity guidance relevant to India’s critical infrastructure sector
Oil and gas industry cybersecurity best practices
Assessment activities are based on these frameworks while considering the operational and safety requirements unique to oil and gas separation facilities.
Importance of OT Security Assessment for Oil & Gas Separation Plants
Oil & Gas Separation Plants operate continuously and depend on tightly integrated industrial control systems. A cybersecurity incident affecting these systems can have significant operational, financial, safety, and environmental consequences.
A comprehensive OT Security Assessment helps organizations:
Identify vulnerabilities across industrial control systems
Protect production automation and process control systems
Strengthen cybersecurity for safety-critical assets
Improve visibility into OT networks and connected devices
Secure industrial communication infrastructure
Detect insecure remote access pathways
Enhance network segmentation
Reduce operational downtime
Improve cyber incident preparedness
Support compliance with industrial cybersecurity standards
Strengthen business continuity and operational resilience
Proactive OT security assessments enable organizations to reduce cyber risks before they affect production or safety.
Our OT Security Assessment Methodology
Cyberintelsys follows a structured, risk-based methodology designed specifically for industrial environments, ensuring comprehensive assessments while minimizing disruption to production operations.
1. OT Asset Discovery and Critical System Identification
The assessment begins with identifying and documenting all critical Operational Technology assets across the separation plant.
Assets commonly reviewed include:

SCADA systems
Programmable Logic Controllers (PLCs)
Remote Terminal Units (RTUs)
Human Machine Interfaces (HMIs)
Engineering workstations
Industrial servers
Safety Instrumented Systems (SIS)
Emergency Shutdown Systems (ESD)
Process analyzers
Tank management systems
Industrial switches
Firewalls
Communication gateways
A complete asset inventory provides the visibility required for effective OT cybersecurity management.
2. Industrial Network Architecture Assessment
Cyberintelsys evaluates the industrial network architecture to understand communication flows, trust boundaries, and potential attack paths.
The assessment includes:
Network segmentation review
OT DMZ implementation
Firewall architecture evaluation
VLAN configuration assessment
