Let's take a look at the features of 'ISO/IEC 27019' with a focus on energy sector ICS security

Here’s a detailed breakdown of ISO/IEC 27019:

ISO/IEC 27019 Breakdown


Definition & Purpose
ISO/IEC 27019 is an extension of ISO/IEC 27001, specifically focused on information security for energy sector control systems (e.g., power plants, electricity grids, gas, and oil industries). It provides guidelines for applying ISO 27002 controls to Industrial Control Systems (ICS) in the energy sector.

Scope
  • Designed for energy sector ICS: SCADA, Distributed Control Systems (DCS), Remote Terminal Units (RTUs), and smart grid technologies.
  • Addresses risks specific to energy infrastructure, including cyber-physical threats and operational disruptions.
  • Extends ISO/IEC 27002 security controls to energy ICS environments.
Key Requirements
  1. Security Governance & Risk Management: Establish a security management system tailored to ICS.
  2. Asset Management & Inventory: Maintain a detailed register of ICS components.
  3. Access Control & Authentication: Implement role-based access control (RBAC), least privilege principles, and multifactor authentication (MFA).
  4. Secure Network Architecture: Use segmentation, firewalls, VPNs, and intrusion detection to isolate critical systems.
  5. System Hardening & Patch Management: Apply secure configurations and timely patches without disrupting operations.
  6. Monitoring & Incident Response: Deploy Security Information and Event Management (SIEM), continuous logging, and forensics for ICS-specific threats.
  7. Supply Chain & Vendor Security: Ensure third-party providers comply with security policies.
  8. Physical Security & Environmental Controls: Restrict access to critical infrastructure and implement protections against physical sabotage.

Special Notes
  • Mandatory? No, but widely used in the energy industry to enhance security and compliance.
  • Extends ISO/IEC 27001 and ISO/IEC 27002, making it more sector-specific.
  • Closely aligns with IEC 62443, particularly for risk-based security approaches in industrial environments.
  • Focused on critical infrastructure: Prevents cyberattacks on power grids, gas pipelines, and renewable energy systems.
  • Compliance with regulatory frameworks: Helps meet energy sector cybersecurity regulations (e.g., NERC CIP in North America, EU NIS2 Directive in Europe).

Recap

  • ISO/IEC 27019 is an extension of ISO/IEC 27001 with a focus on energy sector ICS security.
  • Covers both IT and OT security, ensuring protection of SCADA, DCS, and smart grids.
  • Helps energy companies meet compliance requirements in different regions.
  • Not mandatory, but widely adopted as a best-practice framework for energy cybersecurity.

Don't confuse DCS, PLC and SCADA in front of OT specialists

DCS, PLC and SCADA are not the same. If you keep talking only about PLC security in front of the Oil&Gas industry executives where DCS is the main focus, they will not recognize you as a proper expert. We need to understand the characteristics of OT systems such as DCS, PLC, and SCADA accurately, also respect each OT culture uniquely and finally approach the sites in the right way. Don't be confused, here’s a clear and accurate explanation of DCS, PLC, and SCADA . 1. Distributed Control System (DCS) Concept A DCS (Distributed Control System) is an automated control system used for large-scale industrial processes that require continuous operation and high reliability. It consists of multiple controllers distributed throughout the system, which communicate with each other to manage complex processes. Key Features Used in large-scale, continuous processes (e.g., oil refineries, power plants). Decentralized control architecture with multiple controllers working together. Pr...

A comprehensive list of 20 threat scenarios in OT security along with detailed descriptions and detection rules that can help identify and respond to these threats. This playbook-style table covers different types of attacks—from unauthorized access to insider abuse—with corresponding rules and indicators to alert security teams. # Threat Scenario Detailed Description Detection Rules & Indicators 1 Unauthorized Remote Access Attempt An attacker uses stolen or weak credentials to access OT networks remotely. - Log Analysis: Monitor VPN/RDP logs for unusual login times, geolocation mismatches, and failed/successful login bursts. - User Behavior Analytics (UBA): Alert on deviations from normal remote access patterns. - Anomaly Detection: Trigger an alert when a remote session is initiated from an unusual IP or geographic region. 2 Malware/Ransomware Infiltration in OT Network Malicious code is introduced into the OT network via compromised endpoints or phishing, potentially encr...

Let's create our own ICS Labs in the VMs: A Step-by-Step Guide Building an Industrial Control System (ICS) lab in a virtualized environment allows security researchers, engineers, and penetration testers to safely simulate industrial networks, study threats, and test security defenses. Below is a detailed step-by-step guide to creating an ICS lab , including HMI, EWS, PLC, and other critical components. 1. Lab Architecture Overview Key Components in an ICS Lab: HMI: Graphical interface for controlling industrial processes. Engineering Workstation (EWS): Used to configure PLCs and SCADA systems. PLC: Controls physical processes (e.g., motors, valves). SCADA System: Supervisory control and monitoring of ICS networks. Historian: Logs and stores process data for analysis. Networking Components: Virtualized switches, routers, and firewalls to segment ICS networks. Attacker Machine: Kali Linux or Metasploit for penetration testing. 2. Choosing the Virtualization ...
