Abstract
A file system extension for an endpoint controls access to files by selectively decrypting files under certain conditions. Where a pattern of access to the files suggests malicious and/or automated file access activity, the file system extension may limit the rate of file access by regulating the rate at which decryption is provided to requesting processes.
