Introduction

The Niger Delta is one of Nigeria’s most important oil and gas producing regions, supporting extensive infrastructure for natural gas production, gathering, processing, transportation, storage, and export. Dehydration Plants are critical processing facilities used to remove water vapor and liquid water from natural gas streams before transportation through pipelines, further processing, or delivery to downstream facilities.

Gas dehydration is essential for maintaining product quality, preventing corrosion, reducing hydrate formation, protecting pipelines and equipment, and ensuring safe and efficient gas transportation. These operations depend on reliable Operational Technology (OT) systems that continuously monitor and control process conditions.

Modern Dehydration Plants use interconnected industrial control systems such as Supervisory Control and Data Acquisition (SCADA) systems, Distributed Control Systems (DCS), Programmable Logic Controllers (PLCs), Remote Terminal Units (RTUs), Human Machine Interfaces (HMIs), glycol circulation systems, regeneration control systems, pumps, compressors, control valves, pressure transmitters, temperature transmitters, flow meters, moisture analyzers, Safety Instrumented Systems (SIS), Emergency Shutdown Systems (ESD), Fire and Gas Detection Systems (FGS), process historians, industrial servers, engineering workstations, network switches, industrial firewalls, remote monitoring platforms, and vendor remote access infrastructure.

These systems continuously monitor and control parameters including gas pressure, temperature, flow rate, moisture content, glycol circulation, regeneration temperature, equipment status, valve positions, and alarm conditions. A cyberattack affecting these systems could disrupt dehydration operations, manipulate process parameters, reduce gas quality, compromise safety functions, damage equipment, or create significant operational and environmental consequences.

The increasing convergence of IT and OT networks, remote monitoring, cloud connectivity, Industrial Internet of Things (IIoT) technologies, equipment vendors, contractors, and third-party maintenance access has expanded the cybersecurity attack surface of dehydration facilities.

Threats such as ransomware, malware, unauthorized access, compromised credentials, insecure remote connections, vulnerable legacy systems, insider threats, and supply chain attacks can affect critical dehydration operations.

An OT Security Assessment provides a structured approach to identifying cybersecurity weaknesses across dehydration infrastructure, evaluating existing security controls, and prioritizing improvements according to operational, safety, environmental, and business risks.

Cyberintelsys provides specialized OT Security Assessment services for Dehydration Plants in the Niger Delta, helping organizations protect gas treatment automation, secure industrial control systems, and improve the resilience of critical gas processing operations.

Industry Standards and Compliance

Industrial Cybersecurity Standards for Dehydration Plants

Cybersecurity programs for dehydration facilities should address industrial automation, gas treatment, process safety, equipment reliability, pipeline integrity, environmental protection, and critical infrastructure security.

Organizations can align their OT security programs with recognized standards and frameworks, including:

• IEC 62443 – Security for Industrial Automation and Control Systems
• NIST Cybersecurity Framework (CSF)
• NIST SP 800-82 – Guide to Operational Technology Security
• ISO/IEC 27001 – Information Security Management Systems
• CIS Critical Security Controls

These frameworks support security practices covering:

• OT asset identification
• Asset criticality classification
• Network segmentation
• Secure remote access
• Identity and access management
• Vulnerability management
• Security monitoring
• Incident response
• Backup and recovery
• Business continuity
• Industrial security governance

A standards-aligned approach helps dehydration plant operators strengthen cybersecurity while maintaining the safety, reliability, and availability required for continuous gas treatment operations.

Importance of OT Security Assessment

Dehydration Plants operate highly interconnected process environments where OT systems directly influence gas treatment, glycol circulation, regeneration, pressure management, moisture monitoring, and emergency shutdown functions.

A cyber incident affecting these systems could result in manipulated process parameters, unauthorized equipment commands, loss of process visibility, inadequate dehydration, production disruption, compromised safety systems, equipment damage, or environmental incidents.

Potential OT Cybersecurity Risks

• Unauthorized access to dehydration control systems
• Manipulation of gas pressure settings
• Unauthorized changes to regeneration temperature settings
• Manipulation of moisture measurements
• Compromise of PLCs and RTUs
• Compromise of SCADA and DCS systems
• Unauthorized control of pumps and compressors
• Manipulation of control valve settings
• Compromise of glycol circulation systems
• Unauthorized changes to process configurations
• Compromise of SIS and ESD systems
• Compromise of Fire and Gas Detection Systems
• Weak privileged account controls
• Insecure engineering workstations
• Legacy industrial systems with outdated firmware
• Unpatched operating systems
• Insecure remote maintenance connections
• Poor IT/OT network segmentation
• Malware and ransomware
• Insider threats
• Third-party access risks
• Supply chain vulnerabilities

An OT Security Assessment helps identify these risks before they can significantly affect gas quality, processing continuity, pipeline integrity, process safety, equipment reliability, or business operations.

Key Benefits

A comprehensive assessment can help organizations achieve:

• Improved visibility into dehydration plant OT assets
• Identification and prioritization of cybersecurity vulnerabilities

A risk-based assessment helps operators prioritize remediation based on the criticality of control, safety, communication and supporting OT infrastructure.

Our OT Security Assessment Methodology

1. OT Asset Discovery and Criticality Classification

The assessment begins by identifying and classifying OT assets supporting dehydration plant operations, including:

• SCADA and DCS
• PLCs, RTUs and HMIs
• SIS, ESD and Fire and Gas Detection Systems
• Dehydration, glycol circulation and regeneration control systems
• Compressors, pumps, valves and process instrumentation
• Engineering workstations, servers and process historians
• Network switches, industrial firewalls and remote access infrastructure

Assets are classified based on their operational, safety, environmental and production criticality.

2. OT Architecture and Network Security Review

The assessment examines communication pathways between dehydration control systems, field instrumentation, safety systems, production networks, centralized control centers, corporate IT environments, and external service providers.

The review may include:

• OT architecture and IT/OT connectivity
• Network segmentation, security zones and conduits
• Industrial firewall configurations
• SCADA and DCS communication paths
• PLC, SIS and ESD networks
• Process instrumentation and control networks
• Remote access and vendor connectivity
• Industrial communication protocols and network monitoring
• OT-to-enterprise data flows

The objective is to identify unnecessary exposure and potential attack paths toward critical dehydration and safety systems.

3. OT Vulnerability Assessment

A controlled vulnerability assessment evaluates cybersecurity weaknesses across dehydration plant OT assets.

Activities can include:

• Security configuration, firmware and patch management reviews
• User privilege and industrial device assessments
• SCADA, DCS, PLC, RTU and HMI security assessments
• SIS, ESD and FGS security assessments

• Engineering workstation, server and network infrastructure assessments

Testing is carefully coordinated to minimize operational impact and protect live dehydration processes. OT assessments are typically designed around passive review, architecture validation, and carefully controlled testing to avoid disrupting production systems.

4. Risk Analysis and Security Control Validation

Following the vulnerability assessment, identified cybersecurity weaknesses are evaluated based on technical severity, asset criticality, operational impact, process safety implications, environmental consequences, and business risk.

The security control review can include:

• Identity, access and privileged account management
