This repository defines the Open Cybersecurity Schema Framework (OCSF) schema. OCSF is a framework for creating schemas and it also delivers a cybersecurity event schema built with the framework.
The framework is made up of a set of categories, event classes, data types, and an attribute dictionary. The framework is not restricted to cybersecurity nor to events, however the initial focus of the framework has been a schema for cybersecurity events. A schema browser for the cybersecurity schema can be found at schema.ocsf.io. This is the recommended way to explore the schema.
OCSF is agnostic to storage format, data collection and ETL processes. The core schema for cybersecurity events is intended to be agnostic to implementations. The schema framework definition files and the resulting schema are written as JSON.
OCSF is intended to be used by both products and devices which produce log events, analytic systems, and logging systems which retain log events.
For more information about concepts in OCSF, please refer to the OCSF White paper, Understanding OCSF.
