Driver Code Integrity Attestation Against DSE Bypass

The patent implements preliminary action by establishing a baseline state of internal OS data structures before driver loading occurs. The attestation logic captures and stores baseline values of critical data structures, then compares them against current values during runtime to detect any tampering attempts before they can compromise system integrity. This proactive approach prevents bypass attacks by detecting anomalies in advance.

The patent implements feedback mechanisms through continuous monitoring and comparison of internal OS data structures. The attestation logic repeatedly compares current values against baseline values, creating a feedback loop that detects deviations caused by malicious activities. This real-time feedback enables the system to identify and respond to bypass attempts as they occur, maintaining code integrity despite the presence of vulnerabilities.

The patent applies the taking out principle by extracting and isolating specific critical internal OS data structures that are most susceptible to tampering. Rather than monitoring all system data, the attestation logic focuses on a select subset of baseline values that are essential for code integrity verification. This selective approach maintains high detection precision while minimizing the complexity overhead of the verification system.

The patent implements local quality by applying different verification strategies to different parts of the system. The attestation logic selectively monitors specific internal OS data structures with high precision while leaving other non-critical areas with lower monitoring intensity. This differentiated approach optimizes detection precision for critical areas without uniformly increasing system complexity across all components.
