A security server transmits a specification of a first set of files and directories to a computing device for monitoring according to a security policy. Each of the files or directories in the first set is associated with the operating system of the computing device or associated with an application running on the computing device. The server securely receiving data collected at the remote computing device, which includes metadata for the files and directories and content signatures computed for each file. The server compares the received metadata and content signatures for each file or directory against corresponding baseline metadata and baseline content signatures. The baseline metadata and baseline content signatures are stored at the security server. When there is a mismatch between the received metadata and corresponding baseline metadata or a mismatch between a received content signature and a corresponding baseline content signature, the server performs a remedial action.
