The Open Cybersecurity Schema Framework (OCSF) is a framework designed for creating standardized cybersecurity event schemas. The framework provides a structured approach to defining cybersecurity events and data formats that can be used across different security tools and platforms. It operates independently of specific storage formats, data collection methods, and ETL (Extract, Transform, Load) processes. OCSF schemas are written in JSON format, making them accessible and interoperable across various systems. The framework includes a schema browser that allows users to explore and understand the available schema definitions. The framework is designed to be used by security products, devices, analytic systems, and logging systems to ensure consistent data representation and improve interoperability between different cybersecurity tools and platforms.
