SGInnovate x Three North Stars Tech Talk: Mastering Proactive OT/ICS Cybersecurity with CTEM and Claroty

Course Description & Learning Outcomes

Part 1: Introduction to Continuous Threat Exposure Management (CTEM) Services 

In today's dynamic threat landscape, a reactive approach to cybersecurity is no longer sufficient, especially for critical infrastructure. This introductory session will cover: 

• What is CTEM? Understand the core principles of CTEM, a strategic and systematic approach to continuously identify, prioritize, validate, and remediate cyber exposures. We'll explore how CTEM shifts cybersecurity from a reactive, incident-driven model to a proactive, exposure-focused one.  

• Why CTEM for OT? Discover the unique benefits of implementing a CTEM program within OT environments. Learn how it helps in:

  • Gaining a clear understanding of your organization's attack surface, including OTspecific assets.  

  • Prioritizing vulnerabilities based on their actual exploitability and potential business impact, rather than just CVSS scores.  

  • Reducing the "exposure window" and minimizing the likelihood of successful attacks.  

  • Aligning security efforts with business objectives by focusing on the most critical risks.  

  • Improving security posture and operational resilience.  

The Five Stages of CTEM: We'll walk through the key phases of a successful CTEM program:  

• Scoping: Defining the boundaries and critical assets for your exposure management efforts.  

• Discovery: Identifying all assets within the defined scope, including hardware, software, and communication pathways.  

• Prioritization: Analyzing and ranking exposures based on exploitability, business impact, and active threats. 

• Validation: Confirming the exploitability of prioritized exposures and the effectiveness of existing controls.  

• Mobilization: Implementing remediation actions and continuously monitoring for new exposures.  

Part 2: Hands-On OT/ICS Security with Claroty 

This interactive session will provide a practical demonstration of Claroty's capabilities in securing OT and ICS environments. You will see firsthand how Claroty can help your organization: 

• Achieve Comprehensive Asset Visibility: 

• Deep Packet Inspection (DPI): Witness how Claroty passively monitors network traffic to automatically discover and profile all OT assets, including Programmable Logic Controllers (PLCs), Remote Terminal Units (RTUs), Human-Machine Interfaces (HMIs), and other industrial devices.  

• Detailed Asset Inventory: Explore the rich contextual information gathered for each asset, such as vendor, model, firmware version, communication patterns, and operational criticality.  

• Master Vulnerability Management: 

  • Automated Vulnerability Identification: See how Claroty identifies known vulnerabilities (CVEs) affecting your specific OT assets by correlating asset details with its extensive vulnerability database.  

  • Prioritization with Context: Learn how Claroty goes beyond simple vulnerability scanning by prioritizing vulnerabilities based on their exploitability, whether they are actively being exploited in the wild (leveraging CISA KEV catalog and EPSS), and the potential impact on your operational processes.  

  • Focus on Real Known Exploited Vulnerabilities: Understand how to identify and address vulnerabilities that pose an immediate and proven threat.  

• Enhance Threat Detection: 

  • Baseline Network Behavior: Observe how Claroty establishes a baseline of normal network communication patterns within your OT environment. 

  • Anomaly Detection: See real-time alerts for deviations from the baseline, indicating potential malicious activity, misconfigurations, or operational issues.  

  • Signature-Based Detection: Understand how Claroty detects known OT-specific malware and attack techniques.  

  • Operational Alerts: Gain insights into non-security-related operational events that could impact production or safety.
