OpenDXL Ontology: An open source language for connecting cybersecurity tools - Help Net Security

The Open Cybersecurity Alliance (OCA) today announced the availability of OpenDXL Ontology, the first open source language for connecting cybersecurity tools through a common messaging framework.



With open source code freely available to the security community, OpenDXL Ontology enables any tool to automatically gain the ability to communicate and interoperate with all other technologies using this language. By eliminating the need for custom integrations between individual products, this release marks a major milestone in the OCA’s mission to drive greater interoperability across the security industry.


Automatically connecting cybersecurity tools


The Open Data Exchange Layer (OpenDXL) is an open messaging framework that over 4,100 vendors and enterprises already utilize to develop and share integrations with other tools. The release of the OpenDXL Ontology now offers a single, common language for these notifications, information and actions across security products that any vendor can adopt in order to communicate in a standard way with all other tools under this umbrella. This provides companies with a set of tooling that can be applied once and automatically reused everywhere across all product categories, while also eliminating the need to update integrations as product versions and functionalities change.


For example, if a certain tool detects a compromised device, it could automatically notify all other tools and even quarantine that device using a standard message format readable by all. While previously this was only possible with custom integrations between individual products, it will now be automatically enabled between all tools that adopt OpenDXL Ontology. Through continued development by the community, this common language will facilitate a wide variety of interoperability uses case, from sharing threat intelligence to triggering remediation between tools, such as isolating a device or updating a ..
