OT/ICS Cybersecurity and DCS Training Overview

 

Training in Operational Technology (OT), Industrial Control Systems (ICS), and Distributed Control Systems (DCS) focuses on securing, operating, and maintaining the systems that manage physical processes in critical infrastructure and manufacturing.

OT/ICS Cybersecurity Training

OT/ICS Cybersecurity training is specialized because these environments prioritize safety and uptime over confidentiality, a key difference from traditional IT security. DCS systems are a type of ICS, so OT/ICS security training often covers DCS elements.

Key Training Focus Areas:

• Understanding the Environment: Differences between IT (Information Technology) and OT (Operational Technology), and the unique risks in industrial control systems.

• Architectures and Components: Learning about the Purdue Model, network segmentation, and components like PLCs, SCADA, and DCS.

• Standards and Frameworks: Training on critical standards such as IEC 62443 and guidance from organizations like NIST SP 800-82 and MITRE ATT&CK for ICS.

• Threats and Defense: Identifying specific OT attack methodologies and implementing defense-in-depth strategies.

• Protocols: In-depth study of industrial protocols like Modbus, OPC UA, Profinet, and DNP3.

• Incident Response: Developing and practicing incident response plans tailored for operational environments.

Prominent Training Providers:

Major providers offer both instructor-led and self-paced/online courses:

• SANS Institute (ICS Security): Offers hands-on, in-depth courses leading to certifications like the GIAC Global Industrial Cyber Security Professional (GICSP).

• CISA (Cybersecurity and Infrastructure Security Agency): Provides free, globally recognized web-based and instructor-led training for critical infrastructure professionals.

• Idaho National Laboratory (INL): Offers advanced training, including competitive Red-Blue team exercises.

• EC-Council: Has courses focused on ICS/SCADA Cybersecurity, often including offensive and defensive tactics.

DCS Training

Distributed Control Systems (DCS) are complex, high-reliability control systems used to manage and automate continuous, large-scale industrial processes (e.g., in oil and gas, chemical plants, power generation). DCS training is generally focused on the operation, engineering, and maintenance of the control system itself, and may not always include a heavy security component unless it is a dedicated security course.

Key Training Focus Areas:

• System Operation: Learning to monitor, control, and tune processes using the DCS human-machine interface (HMI).

• Control Loop Tuning: Understanding and optimizing feedback control loops for stability and efficiency.

• Configuration and Engineering: Programming controllers, configuring I/O, developing control strategies, and implementing changes.

• System Maintenance: Troubleshooting hardware and software issues, performing backups, and patch management.

• Specific Vendor Systems: Training is often vendor-specific (e.g., Emerson DeltaV, Honeywell Experion, Siemens PCS 7, ABB 800xA).

Note: Some search results for "DCS training" also referred to Departments of Child Services or similar government agencies (like in Tennessee and Georgia), which is a common acronym in other fields.
