Container Layer Diff Scanning for Cybersecurity Risk Source Tracking

The patent segments the container image into multiple layers and identifies dependency relationships between them. By analyzing the layer dependency graph, the system determines which layers are independent and can be scanned separately, avoiding redundant scanning of shared base layers across multiple containers. This segmentation approach maintains comprehensive threat detection while significantly reducing processing time.

The patent implements partial scanning by focusing only on the necessary layers based on container dependency analysis. Instead of scanning all layers of all container images exhaustively, the system performs scanning on a selective basis - only on layers that are unique to specific containers or have changed, thereby reducing processing time while maintaining adequate detection coverage.

The patent segments container images into layered structures and analyzes dependencies between layers. By identifying which layers are shared across multiple containers versus which are unique, the system stores security scan results selectively - only storing detailed scan data for unique layers while referencing shared base layer results, thereby reducing storage resource consumption while maintaining comprehensive detection capability.

The patent uses copying by storing security metadata and vulnerability information in a centralized repository that can be referenced by multiple containers. Instead of duplicating full scan results for every container, the system stores a copy of the layer dependency graph and security findings that can be efficiently queried and applied across multiple containers, reducing overall storage requirements.

The patent segments the container ecosystem into discrete layers with explicit dependency relationships. By building a layer dependency graph that identifies which containers share which base layers, the system performs security scanning only on the necessary unique portions of each container image. This eliminates redundant detection of the same vulnerabilities in shared base layers while maintaining accurate threat detection for unique container-specific layers.

The patent performs preliminary analysis of container layer dependencies before executing security scans. By pre-computing the layer dependency graph and identifying which layers need to be scanned based on container relationships, the system avoids redundant scanning operations. This preliminary action optimizes the scanning process by directing resources only to necessary layers, improving productivity while maintaining detection accuracy.
