Security Aware Partitioning for Efficient File System Search

Index partitioning techniques—where indexes are broken into multiple distinct sub-indexes—are a proven way to improve metadata search speeds and scalability for large file systems, permitting early triage of the file system. A partitioned metadata index can rule out irrelevant files and quickly focus on files that are more likely to match the search criteria. Also, in a large file system that contains many users, a user’s search should not include confidential files the user doesn’t have permission to view. To meet these two parallel goals, we propose a new partitioning algorithm, Security Aware Partitioning, that integrates security with the partitioning method to enable efficient and secure file system search.
