In this three-part series, we focus on Data Distribution Service (DDS), which drives systems such as railways, autonomous cars, spacecraft, diagnostic imaging machines, luggage handling, and military tanks, among others. We\u2019ll also explore the current status of DDS and highlight recommendations enterprises can take to minimize the threats associated with this middleware.<\/p>\n

But first, let\u2019s discuss what DDS is and how it is applied in various industries.<\/p>\n

Overview<\/span><\/p>\n

DDS is a standardized middleware software based on the publish-subscribe paradigm, helping the development of middleware layers for machine-to-machine communication. This software is integral especially to embedded systems or applications with real-time requirements. Maintained by the Object Management Group (OMG),7 DDS is used in all classes of critical applications to implement a reliable communication layer between sensors, controllers, and actuators.<\/p>\n

DDS is at the beginning of the software supply chain, making it easy to lose track of and is an attractive target for attackers. Notably, the following companies and agencies use DDS (note that this is not an exhaustive list of currently using this technology):<\/p>\n
