• Method Contract Verification - Verifies that method overrides satisfy required symmetry and transitivity contracts for consistency.
• Bug Pattern Categorization - Maps detectors to specific categories using configuration files to organize reported findings.
• XSS Detection - Identifies cross-site scripting and path traversal vulnerabilities in Java servlets and JSPs.
• SQL Injection Detection Tools - Uses data flow analysis to detect SQL statements where non-constant strings are passed to execution methods.
• Dead Code Detectors - Detects unused methods, unread fields, and obsolete variable assignments that can be removed.
• False Positive Filtering - Suppresses warnings by identifying intentional patterns and defining specific assertion methods.
• Naming Conventions - Verifies that class and method names adhere to standard casing and naming rules.
• Plugin System Extensions - Integrates external plugins to add new detection rules and security checks to the analysis process.
• Detector-Based Plugin Architectures - Provides a modular architecture that allows external libraries to inject custom bug detectors into the analysis pipeline.
