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
1
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.
2
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.
3
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.
4
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.
5
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.
6
7
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.
8
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.
