  • Patent number: 9576144
    Abstract: Systems and methods for accessing data secured and encrypted using a file system manager are disclosed. One method includes determining whether a community of interest (COI) key obtained from a security appliance matches a COI key associated with a file structure managed by the file system manager that is the subject of a file system request issued by a caller. The method further includes identifying an entry included in a key bank associated with the COI key and the file structure that is the subject of the file system request, the key bank storing encrypted versions of a metadata key. The method also includes decrypting the metadata key using the COI key, decrypting at least one block encryption key using the metadata key, and decrypting a block of data associated with the at least one block encryption key.

  • Patent number: 9514325
    Abstract: Systems and methods for establishing a secure file system are disclosed, in which system endpoints such as files and directories in a file system are protected using a security appliance. The security appliance protects each endpoint in the file system from unauthorized access by making those endpoints invisible to unauthorized users. The security appliance organizes users and endpoints into various communities of interest (COI). A user COI groups users such that all users associated with that particular COI have authorization to view the same one or more endpoints located in file storage.
