Concurrent file system searches for vulnerability detection
A recently granted patent (Publication Number: US11921673B2) discloses a method and system for file system search proxying (FSSP) to efficiently conduct vulnerability searches on computing devices. The method involves receiving multiple search requests with specific criteria, identifying common search roots, and executing concurrent searches on the file system using window functions to map and evaluate candidates against the search criteria. By performing searches in parallel processes or threads, redundant traversals of the file system are minimized, leading to more efficient results reporting. The system includes computing devices implementing FSSP, capable of receiving search requests, conducting searches, and reporting results, thereby enhancing security vulnerability assessments.
The FSSP system utilizes directed acyclic word graphs (DAWGs) in the search process, including black list DAWGs for excluded nodes and white list DAWGs for defining search roots. The searches aim to identify files with elevated permissions in the file system, with results reported through network interfaces or user interfaces. Additionally, the system can perform searches across multiple computers in a network, assessing security vulnerabilities based on the candidates found. The patent also covers non-transitory computer-readable media storing program instructions to implement the FSSP system, enabling efficient and effective vulnerability searches on file systems while reducing redundant traversals and enhancing overall security assessments.
