ISO 27019
Information Security for Energy Utility Process Control
Secure the operational technology and process control systems that power Indonesia's energy infrastructure — with information security controls purpose-built for the energy sector.
Overview
ISO/IEC 27019 is an information security standard specifically designed for the energy utility industry. It extends the ISO 27002 control set to address the unique information security requirements of process control systems, SCADA systems, distributed control systems (DCS), and associated IT environments used in energy generation, transmission, distribution, and supply.
Indonesia's energy sector — spanning PLN, independent power producers, oil and gas operators, and renewable energy companies — operates critical infrastructure where a cybersecurity incident can have direct physical consequences. ISO 27019 provides the sector-specific security controls needed to protect these environments, complementing ISO 27001 with guidance tailored to operational technology (OT) and industrial control systems (ICS).
Key Benefits
Protect Critical Energy Infrastructure
Implement security controls designed for the operational realities of energy process control — where availability and safety take precedence over confidentiality.
Regulatory & Grid Operator Compliance
Meet information security requirements from energy sector regulators (BPH Migas, ESDM) and grid operators that increasingly mandate cybersecurity standards for connected systems.
Manage OT/IT Convergence Risks
As energy systems connect OT networks to corporate IT and the internet, ISO 27019 provides controls for managing the security risks at these convergence points.
Incident Response for Energy Systems
Establish security incident response procedures that account for the safety-critical nature of energy process control — where the wrong response can be as dangerous as the attack.
Key Requirements
1. Process Control System Asset Inventory
Identify and classify all process control assets — PLCs, RTUs, HMIs, SCADA servers, historian systems — and define their security requirements based on criticality.
2. Network Segmentation & Zone Architecture
Implement security zones and conduits between OT networks and corporate IT networks, with appropriate controls at each boundary to prevent unauthorized lateral movement.
3. Patch & Configuration Management for OT
Manage software updates and configuration changes for process control systems in a way that maintains operational continuity while addressing known vulnerabilities.
4. Remote Access Security
Secure remote access to process control systems used by maintenance engineers, vendors, and operators — a common attack vector in energy sector incidents.
5. Physical Security Integration
Align information security controls with physical security measures for substations, control rooms, and field equipment to prevent physical bypass of digital controls.

Frequently Asked Questions
Do I need ISO 27001 before implementing ISO 27019?
ISO 27019 is designed as a sector-specific extension of ISO 27002 and is typically implemented alongside ISO 27001. It adds energy-specific controls on top of the general information security management framework. Most energy organizations implement ISO 27001 as the foundation and use ISO 27019 to address their OT and process control environment specifically.
How does ISO 27019 relate to IEC 62443?
IEC 62443 is the industrial cybersecurity standard series developed specifically for industrial automation and control systems (IACS) — it is more technically detailed for OT environments. ISO 27019 bridges between ISO 27001/27002 and the energy OT context. Many energy organizations use both: ISO 27001/27019 for the management system and IEC 62443 for deep technical OT security requirements.
Is ISO 27019 applicable to oil and gas companies?
Yes. While originally developed for electricity utilities, ISO 27019 is applicable to any organization operating process control systems in the broader energy sector, including oil and gas production, refining, and pipeline operations.
