As demands rise for connected systems and cloud connectivity, industrial organizations are leveraging one of the most widely used protocols for cloud-based data, Advanced Message Queuing Protocol (AMQP). AMQP provides open communications, however once communications are opened, they need to be secured. Owl has developed an AMQP Protocol Adapter that allows AMQP two-way traffic to be sent over secure, one-way data diodes. The proxies allow Owl’s hardware-enforced data diodes to securely transfer AMQP traffic across the Operational Technology (OT) network boundary to the cloud, corporate data centers, Security Operations Centers (SOC), remote monitoring centers, or anywhere, with no risk of threats entering back into the source network. The AMQP Protocol Adapter combined with a data diode integrates with Amazon Web Services (AWS), AZURE, and other common private clouds, while maintaining the confidentiality, integrity, and availability of OT systems and AMQP messages.
