STONEWORK Ontology

STONEWORK (Semantic Threat Ontology and Research Framework) is an OWL 2 ontology and research framework that serves as the evolutionary successor to the STONES ontology. It extends STONES with classes for security controls, weaknesses, products, tactics, techniques, procedures, threat scenarios, risk, likelihood, and impact — and defines a semantic interoperability layer connecting heterogeneous CTI frameworks such as ATT&CK, CAPEC, CWE, CVE, CPE, and CIS Controls. It is developed and maintained by Hohimer Intelligence Strategies LLC.
