Data-Driven Vulnerability Ontology

Overview This ontology represents an enhanced framework for integrating heterogeneous vulnerability data from multiple authoritative cybersecurity sources. The ontology addresses critical limitations in existing theoretical models by ensuring full coherence with real-world database schemas from CVE, CWE, CAPEC, and CPE repositories. Purpose and Scope The Enhanced Vulnerability Ontology provides a unified semantic framework for representing and reasoning about cybersecurity vulnerabilities, weaknesses, attack patterns, and affected products. It serves as a bridge between theoretical ontological models and practical database implementations, enabling comprehensive analysis of security threats across disparate data sources. Key Features Data-Driven Design Systematically validated against actual database schemas from NIST NVD, MITRE CVE, CWE, CAPEC, and CPE repositories Resolves inconsistencies between theoretical frameworks and real-world data structures Ensures direct correspondence between ontological properties and database fields Comprehensive Coverage CVE (Common Vulnerabilities and Exposures): Complete vulnerability information including CVSS metrics, references, and product configurations CWE (Common Weakness Enumeration): Software and system weaknesses with detailed attributes, mitigations, and examples CAPEC (Common Attack Pattern Enumeration and Classification): Attack patterns with execution flows, prerequisites, and consequences CPE (Common Platform Enumeration): Product and platform information for vulnerability mapping Enhanced Modeling Unified CVSS Integration: Consolidated CVSS metrics representation versus fragmented approaches in prior work Structured References: Enhanced reference classification with tags and metadata Hierarchical Organization: Support for CWE categories and CAPEC abstraction levels Complex Relationships: Rich semantic connections between vulnerabilities, weaknesses, and attack patterns
