Industrial Control Systems (ICS) are critical to the functioning of various sectors such as manufacturing, energy, water, and others. Understanding the security breaches in ICS is vital for cybersecurity professionals, researchers, and organizations. This blog post will guide you through various resources and platforms where you can find comprehensive data on ICS security breaches.

Key Sources for ICS Security Breach Data

  1. SANS ICS Security Survey: Offers quantitative data and recommendations. The SANS Institute conducts regular surveys that provide insight into the current state of security in control systems. You can find the surveys like “The SANS 2016 ICS Survey” and “The State of Security in Control Systems Today” at
  2. ICS-CERT: The Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) provides U.S.-focused data for critical infrastructure industries. It is a reliable source for timely information on current security issues, vulnerabilities, and exploits surrounding ICS. Explore their advisories on ICS-CERT.
  3. RISI Database: The Repository of Industrial Security Incidents (RISI) is a database that offers historical industrial security data. This resource is essential for understanding past trends and patterns in ICS security breaches. Visit RISI for more information.
  4. ARC Advisory Group: They offer resources such as “A Maturity Model for Industrial Cybersecurity Planning,” which can be a valuable tool for understanding and planning for cybersecurity in industrial environments. Their website is ARCweb.
  5. Gartner Group: Known for their market guides, Gartner provides insights into operational technology security, which can be particularly useful for strategic planning and understanding market trends. Find more at Gartner.
  6. CISA Advisories: The Cybersecurity and Infrastructure Security Agency (CISA) releases advisories that are crucial for understanding the latest threats and vulnerabilities in ICS. Their advisories, available at CISA, offer detailed technical information and mitigation strategies.
  7. NIST Guide to ICS Security: The National Institute of Standards and Technology (NIST) provides comprehensive guidance on securing ICS, including SCADA systems, DCS, and PLCs. Their guide addresses typical threats and vulnerabilities and recommends security countermeasures. Access this resource on NIST.

Understanding the ICS Threat Landscape

The threat landscape for ICS is evolving with various internal and external threats. Internal threats may stem from employee negligence or lack of proper cybersecurity training, while external threats could come from nation-states, hacktivists, cybercrime groups, or competitors. These threats can target networks, steal sensitive information, or exploit endpoints in ICS.

Defensive Strategies for ICS

Protecting ICS from cyber threats involves several key strategies:

  • Regular Assessments: Continuously evaluate system configurations, patch levels, and potential threats.
  • Access Restriction: Implement strong access control measures and use technologies like firewalls and VPNs.
  • ICS Security Architecture: Adhere to standards like NIST Cybersecurity Framework and ISA/IEC 62443 for secure ICS environments.
  • Regular Audits: Conduct periodic testing and audits to identify vulnerabilities.
  • Network Segmentation: Divide the network into segments with unique security measures to contain breaches.
  • Modify Default Credentials: Always change default credentials to enhance security.


Staying informed about ICS security breaches and understanding how to protect these systems is crucial for maintaining the integrity and safety of critical infrastructure. By utilizing the resources mentioned above, organizations can enhance their cybersecurity posture against the evolving threat landscape in ICS.
