The Challenge
Lack of OT security visibility, network segmentation and incident management.
- Lack of network segmentation between IT and OT
- No visibility of OT inventory or security incident management
- OT network architecture not aligned with NIST and IEC62443 guidelines
The Objective
Enhance OT security by assessing infrastructure, identifying gaps and implementing monitoring solutions.
- Implement clear network segmentation between IT and OT environments to improve security and compliance
- Conduct thorough assessment and inventory analysis to provide insight into the OT infrastructure
- Set up systems for detecting and managing security incidents, including unauthorized access and other security lapses
The Solution
Assessed and deployed Microsoft Defender for IoT sensors and customized alert mechanisms for anomaly detection.
- Conducted an in-depth evaluation of the OT infrastructure, identifying security vulnerabilities and non-compliance issues in line with NIST and IEC62443 standards
- Successfully deployed 108 sensors (56 physical and 52 virtual) across 58 global sites, enabling real-time monitoring of approximately 10,000 OT devices for inventory management and traffic analysis
- Developed and configured a sophisticated alert mechanism for detecting anomalies, unauthorized device connections and weak password authentications, enhancing incident response capabilities
The Impact
Increased OT visibility, enabled unauthorized access detection and improved overall security management.
- Achieved comprehensive visibility of approximately 10,000 OT devices, enabling better asset management and security monitoring
- Identified and mitigated unauthorized device connections and weak password-based authentications, strengthening the overall security posture
- Established a robust system for real-time anomaly detection and security incident management, ensuring compliance with industrial standards and best practices
