Location:

Deer Park, Texas

Results:

Fortified chemical plant’s OT environment with state-of-the-art protection systems, resulting in enhanced security, improved network traffic visibility, and strengthened firewalls to protect the facility from cyber threats.

Project summary:

For a large chemical manufacturing plant with an aging network infrastructure, its operator sought to modernize systems to achieve higher levels of performance and security. Specialized engineering for network security solutions was key to a successful project outcome. The Deer Park, Texas chemical manufacturer turned to the experienced OT team at Audubon to upgrade its network infrastructure and optimize its security posture.

Audubon first assessed the existing network and identified risks threatening the plant’s digital security, including legacy segmentation practices, obsolete equipment, and no official L2.5 network layer. Our comprehensive assessment found the facility lacked a modern security architecture, with suboptimal routing, concerning network loops, low redundancy for critical connections, and general inefficiencies.

With a custom-engineered security solution, we transformed this insecure, flat network into a robust, secure industrial control network. The Audubon team designed and implemented advanced segmentation and firewall protections for third-party assets, rectified multi-homed device connections, and increased visibility into network traffic for the highest level of integrity. These elements enhanced the facility’s security measures to mitigate potential external supply-chain attacks and prevent the possibility of network propagation. With Audubon spearheading the network upgrades as well as delivering continuous support for configuration and patching, the onsite OT team was able to focus on its core priorities without any distractions.

Scope of work:

• Network assessment
• Engineering & design
• Equipment selection
• Automation & control implementation
• Ongoing configuration support
