The Five ICS Cybersecurity Critical Controls Webcast

Step-by-Step Tutorial: Implementing the Five ICS Cybersecurity Critical Controls

1. Introduction to the Five Critical Controls:

   • Watch the video titled "The Five ICS Cybersecurity Critical Controls Webcast" from the SANS ICS channel on YouTube.
   • Pay attention to the speakers, Robert Lee and Tim Conway, as they discuss the importance of the five critical controls for ICS cybersecurity.

2. Understanding the Discussion:

   • Note that the five critical controls discussed in the video are ICS Instant Response Plan, Defensible Architecture, ICS Network Visibility and Monitoring, Secure Remote Access, and Risk-Based Vulnerability Management.

3. Focus on ICS Instant Response Plan:

   • Understand the necessity of an ICS instant response plan tailored to the unique operations environment of industrial control systems.
   • Develop scenarios and playbooks for potential incidents to ensure a proactive response to any cybersecurity threats.

4. Importance of Defensible Architecture:

   • Implement an architecture that minimizes risk and enables effective defense against potential cyber threats.
   • Consider segmentation, routing, and perimeter defense to protect the ICS environment.

5. Implement ICS Network Visibility and Monitoring:

   • Prioritize network traffic analysis to detect adversary actions and behaviors within the ICS environment.
   • Focus on ICS-specific protocols and behaviors to ensure effective monitoring and threat detection.

6. Secure Remote Access Implementation:

   • Deploy secure remote access solutions with multi-factor authentication to mitigate risks associated with external access to ICS systems.
   • Consider the unique requirements of remote access in ICS environments to prevent unauthorized access.

7. Risk-Based Vulnerability Management:

   • Adopt a risk-based approach to vulnerability management, focusing on vulnerabilities that pose a significant risk to operations.
   • Prioritize vulnerabilities that introduce new functionality, are actively exploited, or allow unauthorized access to the ICS environment.

8. Collaboration and Implementation:

   • Engage key stakeholders, including operations, engineering, IT, and security teams, in the implementation of the five critical controls.
   • Work with vendors and industry partners to align cybersecurity strategies with best practices and industry standards.

9. Further Resources and Implementation:

   • Access the white paper associated with the webcast for detailed insights and guidelines on implementing the five critical controls.
   • Stay updated on upcoming webinars, case studies, and training sessions related to ICS cybersecurity best practices.

10. Conclusion:

• Take proactive steps to implement the five critical controls in your ICS environment to enhance cybersecurity resilience and protect critical operations.
• Continuously monitor and adapt your cybersecurity strategy based on evolving threats and industry best practices.

By following these steps and guidelines from the video, you can effectively implement the five critical controls for ICS cybersecurity in your organization.
