What are the 5 ICS Cybersecurity Controls? Simply ICS Cyber S1 E4

Summary: The video discusses the five critical cybersecurity controls relevant to industrial control systems (ICS) as explained by Michael Hilkin, a cybersecurity professional and operator in the Pennsylvania Air National Guard. The discussion emphasizes the importance of each control, including incident response, defensible architecture, network visibility monitoring, secure remote access, and risk-based vulnerability management. The hosts and guest engage in a deep conversation about these critical areas, providing practical insights for practitioners in the field.

Keypoints:

• The five ICS cybersecurity controls focus on a pragmatic approach to security, helping practitioners defend their environments effectively.
• Incident response plans are crucial for recovery during security incidents and should be practiced regularly.
• Defensible architecture is fundamental to security, including physical and logical separation of networks and identifying crown jewels.
• Network visibility monitoring is essential to understand and track communications within the network.
• Secure remote access needs to be managed carefully to prevent unauthorized access; thorough monitoring of access is vital.
• Risk-based vulnerability management helps prioritize patching efforts, focusing on the most critical areas of the network for security improvements.
• Engaging with other stakeholders and understanding the operational environment is key to implementing effective security measures.
• Vulnerability assessments and managing known exploited vulnerabilities are important to reduce the risk of attacks.
