Risk Management for Industrial Control Systems (ICS): Checklist for CISOs
Risk Management for ICS: Checklist for CISOs" is a checklist when assessing and mitigating risks associated with ICS. The guide covers the following 9 key areas
Understand the unique characteristics of ICS and the associated risks: This includes identifying the critical assets and their dependencies, and understanding the specific threats and vulnerabilities that ICS face
Develop a risk assessment methodology: This includes identifying and prioritizing assets, identifying threats and vulnerabilities, and assessing the likelihood and impact of potential attacks.
Implement risk mitigation strategies: This includes implementing measures such as network segmentation, access controls, and incident response planning to reduce the likelihood and impact of potential attacks.
Regularly evaluate and update the risk management program: This includes regularly reviewing the risk assessment methodology, updating the risk register and incident response plan, and evaluating the effectiveness of risk mitigation measures.
Ensure compliance with relevant regulations and industry standards: This includes understanding and adhering to regulations and standards such as NIST Cybersecurity Framework, IEC 62443, and the ISA/IEC 62443 series of standards.
Foster a culture of security awareness and training among employees and contractors: This includes providing regular security training and awareness programs to employees and contractors, and ensuring that they are aware of the security risks and best practices for protecting industrial systems.
Regularly conduct security assessments and penetration testing: This includes conducting regular security assessments and penetration testing to identify vulnerabilities and evaluate the effectiveness of security controls.
Develop incident response plan: This includes having a plan in place for responding to security incidents, including communication protocols, roles and responsibilities, and incident response teams.
Address the security of third party devices and components: This includes assessing the security of third party devices and components that are used in the industrial systems, and ensuring that they are secure and configured correctly.
