1. A data governance system for use with an existing organizational file system, said data governance system comprising a non-transitory, tangible computer-readable medium in which computer program instructions are stored, which instructions, when read by a computer, cause the computer to automatically manage access permissions, said system comprising: a probe engine communicating with said organizational file system and being operative to collect access information from said organizational file system in an ongoing manner; a redundancy reducing engine receiving an output from said probe engine and providing a redundancy reduced information stream; and a redundancy reduced information database receiving and storing said redundancy reduced information stream; said redundancy-reduced information database storing information relating to a subset of a set of access permissions to said organization file system, said subset being created by said redundancy reducing engine, said redundancy reducing engine being operative: to ascertain which of a multiplicity of access permissions to said organization file system are unique access permissions, said unique access permissions being access permissions which are not inherited; to ascertain which of said multiplicity of access permissions to said organization file system are inherited access permissions; to ascertain whether any of said unique access permissions are redundant with any of said inherited access permission; and responsive to said ascertaining whether any of said unique access permissions are redundant with any of said inherited access permissions, to eliminate from said multiplicity of access permissions to said organization file system, said unique access permissions to said organization file system which are redundant with said inherited access permissions.
