Industry: Beverage Manufacturing
Project Overview:
Lion recognized the need to modernize and secure its OT infrastructure by implementing a comprehensive network segmentation strategy. The objective was to isolate critical systems, reduce the risk of lateral movement, and improve overall visibility and control.
Challenges:
- The OT network was largely flat, allowing unrestricted communication between devices.
- There was minimal separation between IT and OT environments, increasing exposure to external threats.
- Legacy systems lacked native security controls, making them vulnerable to exploitation.
Solution:
Sydco conducted a detailed network assessment and designed a segmentation model based on the Purdue Enterprise Reference Architecture. Next-generation firewalls, VLANs, and granular firewall polices were deployed to create secure zones for different OT functions. Communication pathways were tightly controlled, and monitoring was introduced at key junctions.
Results:
- The OT environment became more resilient to cyber threats by limiting unnecessary communication.
- Security teams gained clearer visibility into traffic patterns and potential anomalies.
- The segmentation laid the foundation for future compliance with industry standards and frameworks.
