Introduction
Clear water storage and reservoir systems play a critical role in maintaining reliable water supply across the United States. These facilities store treated water before it is distributed to communities, industrial facilities, and other essential users. Modern clear water storage and reservoir systems increasingly depend on interconnected Operational Technology (OT) environments that include Industrial Control Systems (ICS), Supervisory Control and Data Acquisition (SCADA) systems, Programmable Logic Controllers (PLCs), Human-Machine Interfaces (HMIs), sensors, and industrial communication networks.
These technologies support critical functions such as water level monitoring, reservoir control, pump operation, pressure management, valve control, water quality monitoring, and automated distribution processes. As water infrastructure becomes increasingly connected, the integration of IT and OT networks, remote access capabilities, wireless technologies, and third-party maintenance services can increase the cybersecurity attack surface.
Cybersecurity weaknesses within these environments may allow unauthorized users to access operational systems, manipulate control parameters, disrupt monitoring capabilities, or interfere with water distribution processes. A cyber incident affecting clear water storage or reservoir operations could potentially impact service continuity, water management, and public safety.
An OT Security Assessment helps water utilities identify cybersecurity weaknesses across their operational environments, evaluate existing security controls, and strengthen the resilience of critical water infrastructure against evolving cyber threats.
Regulations and Cybersecurity Requirements for Water Infrastructure
Clear water storage and reservoir systems can align their cybersecurity programs with internationally recognized standards and frameworks to strengthen the protection of OT, ICS, SCADA, and other operational environments. Relevant cybersecurity references include:
ISO/IEC 27001 – Provides a globally recognized framework for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS).
ISA/IEC 62443 – Provides cybersecurity standards and best practices specifically designed for industrial automation and control systems (IACS), including OT environments, system security, and risk assessment.
NIST Cybersecurity Framework (CSF) – Provides a structured approach for identifying, protecting, detecting, responding to, and recovering from cybersecurity risks.
NIST SP 800-82 – Provides guidance for securing Operational Technology (OT), including Industrial Control Systems (ICS), SCADA systems, PLCs, and other control environments.
Aligning OT security assessments with these internationally recognized standards helps organizations identify vulnerabilities, evaluate security controls, strengthen risk management, and improve the cybersecurity resilience of critical water infrastructure.
Importance of OT Security Assessment for Clear Water Storage and Reservoir Systems
Clear water storage and reservoir facilities operate continuously and depend on OT systems for monitoring and controlling essential processes. A cybersecurity incident affecting these systems could disrupt water storage, distribution, pressure management, or operational visibility.
Core operational functions commonly supported by OT environments include:
Water level and reservoir monitoring
Pump and motor control
Automated valve operations
Pressure monitoring and management
Water quality and environmental parameter monitoring
Potential cybersecurity threats affecting these environments include unauthorized access to SCADA systems, exploitation of vulnerable PLCs and HMIs, insecure remote connections, manipulation of operational parameters, malware affecting engineering workstations, and unauthorized access through third-party connections.
An OT Security Assessment helps identify these weaknesses before they can be exploited. It provides organizations with greater visibility into their operational security posture while helping prioritize remediation activities based on potential operational impact.
Our OT Security Assessment Methodology for Clear Water Storage and Reservoir Systems
A structured assessment methodology helps evaluate the security of OT environments while minimizing potential disruption to critical water operations. The assessment focuses on understanding the operational environment, identifying vulnerabilities, reviewing security controls, and evaluating potential attack paths.
1. Asset Identification and OT System Mapping
The assessment begins with identifying and documenting critical assets within the clear water storage and reservoir environment.
Key activities include:
Mapping SCADA servers, PLCs, HMIs, and engineering workstations
Identifying sensors, controllers, pumps, valves, and associated devices
Reviewing OT network infrastructure and communication pathways
Identifying remote access systems and third-party connections
Documenting critical operational assets and dependencies
This establishes visibility into the OT environment and helps identify systems that require additional security protection.
2. Threat and Vulnerability Analysis
A detailed assessment is conducted to identify vulnerabilities and potential threat vectors affecting operational systems.
The assessment may include:
Identifying vulnerable or outdated OT components
Reviewing system and device configurations
Evaluating authentication and authorization mechanisms
Assessing exposed services and insecure interfaces
Reviewing vulnerabilities affecting SCADA, PLC, HMI, and supporting systems
This helps determine how existing weaknesses could affect the security and availability of water operations.
3. OT Network Architecture and Segmentation Review
Network architecture is evaluated to determine whether critical operational systems are adequately isolated and protected.
Key areas include:
IT/OT network segmentation
Firewall configurations and access control rules
Communication between SCADA, PLC, HMI, and field devices
Remote access pathways
Third-party connectivity
Secure communication between operational zones
Effective network segmentation can reduce unauthorized access and limit potential lateral movement following a security compromise.
4. Security Control Evaluation
Existing cybersecurity controls are assessed to determine whether they provide appropriate protection for operational systems.
Key evaluation areas include:
Identity and access management
Privileged account controls
Multi-factor authentication where applicable
System hardening and secure configurations
Patch and vulnerability management
Endpoint protection
Security logging and monitoring
Backup and recovery mechanisms
The assessment helps identify gaps between existing controls and recommended OT security practices.
5. Risk Evaluation and Security Validation
Identified vulnerabilities are evaluated based on their potential impact on operational systems and water infrastructure.
Where technically safe and appropriate, controlled validation may be performed to determine whether identified weaknesses are practically exploitable. Testing is planned carefully to avoid disruption to active water treatment, storage, pumping, or distribution operations.
The assessment considers:
Potential attack paths
Exploitability of identified weaknesses
Operational impact
Security control effectiveness
Potential consequences of unauthorized access
6. Remediation and Security Recommendations
The final stage provides prioritized recommendations to address identified security gaps.
Recommended measures may include strengthening network segmentation, improving access controls, securing remote connectivity, hardening OT devices, improving vulnerability management, enhancing monitoring capabilities, and strengthening incident response procedures.
