Data diode solutions for enhanced cybersecurity

Get Started

Check out the below resources to learn more about how power organizations are preventing cyber-attacks and securely sharing data between power plants and destination networks, like historians, SIEM platforms, IT networks, and the cloud.

Prevent Power Delivery Outages

The power industry faces three main challenges when it comes to cybersecurity; protecting Operational Technology (OT) networks, securely sharing data, and meeting regulatory compliance. Previous methods of securing OT networks, like relying on software-based firewalls, no longer suffice as threats like ransomware rise and become more sophisticated. While complete isolation of OT networks provides the highest level of security, it prevents the ability to get critical network data to those that need it. The only solution for truly protecting OT networks and enabling secure data mobility, while operating within regulatory compliance, is by implementing hardware-enforced data diode cybersecurity.

Securely Transfer Data To Those Who Need It

Data diodes provide power organizations with a secure way to transfer critical data one-way out of OT networks to destinations like IT networks, historians, SIEM platforms, or the cloud, without introducing risk to OT networks. Owl data diodes are comprised of two communication cards that work as a pair. The first card is the “send” card and only has electronic components that allow it to send data one-way, with no ability to receive. The second card, the “receive” card, only has electronic components that allow it to receive data. This architecture only allows data to flow in one direction and it physically cannot travel the other way. Because a data diode is only physically capable of sending data one-way, a data diode creates a physical barrier or “air gap” between an OT network and a destination. This prevents data leakage, eliminates the threat of malware, and fully protects the sending network from external threats through the data diode’s network path.

Meeting Regulatory Compliance

Power organizations are held to a higher standard when it comes to the cybersecurity technologies they deploy compared to other critical infrastructure industries, resulting in the need to deploy solutions that adhere to compliance requirements and provide the highest level of security possible to prevent power delivery outages. Regulatory compliance standards that impact the power industry are NRC, NERC-CIP, and NIST. Owl data diodes map to these regulatory controls and are recommended as a best practice for securing OT networks, while enabling data mobility.
