Machine-Checkable Code Annotations for SAST False Positives

The patent applies preliminary action by performing static analysis before code execution to identify potential vulnerabilities. The system proactively detects security issues in advance, allowing developers to address them before deployment. This preliminary detection phase separates automated analysis from manual verification, reducing the need for time-consuming manual audits of false positives.

The patent introduces an intermediary mechanism in the form of a verification system that acts as a mediator between static analysis tools and manual audits. This intermediary automatically verifies detected vulnerabilities using multiple analysis techniques and confidence scoring, filtering out false positives before they reach manual reviewers. This reduces manual audit time while maintaining detection reliability.

The patent applies partial action by implementing a multi-level verification process that selectively applies different verification techniques based on the detected vulnerability's characteristics and confidence score. Not all vulnerabilities undergo the same level of verification - high-confidence findings receive minimal verification while low-confidence findings undergo extensive analysis. This balances detection completeness with precision, reducing false positives without missing critical vulnerabilities.

The patent changes parameters by introducing confidence scoring and adjusting verification thresholds dynamically. The system monitors false positive rates and adjusts the stringency of verification based on observed performance. This parameter adjustment allows the system to maintain high detection completeness while improving classification accuracy by being more selective about which findings require manual verification.

The patent segments the security analysis system into modular components: initial detection module, verification module, confidence scoring module, and policy enforcement module. Each segment handles a specific aspect of vulnerability analysis independently. This segmentation allows complex security policies to be implemented as separate, manageable rules in the policy enforcement module without overwhelming the entire system, maintaining precision while controlling complexity.

The patent creates a universal verification framework that handles multiple vulnerability types and detection methods through a single integrated system. The verification module can apply different techniques (dynamic analysis, symbolic execution, taint analysis) based on the specific vulnerability context. This multi-functional approach reduces overall system complexity by providing a unified policy enforcement mechanism rather than separate complex policies for each vulnerability type.

The patent performs preliminary automated verification of all detected vulnerabilities before they reach manual auditors. The verification system uses multiple analysis techniques to pre-screen findings, eliminating obvious false positives in advance. This preliminary action ensures that manual auditors only review high-confidence, pre-verified findings, maximizing verification accuracy while minimizing the number of expensive manual audit hours required.

The patent implements self-service verification where the system automatically verifies its own findings using internal validation mechanisms. The verification module acts as a self-check system that can independently confirm or refute detected vulnerabilities without external intervention. This self-service capability reduces reliance on expensive manual audits while maintaining high verification accuracy for the subset of findings that do require human review.
