Abstract
Apparatus, methods and articles of manufacture for file integrity and baseline maintenance on a computer system or systems are shown. A file integrity check is made of files on a system by hashing the files and comparing the hash to a stored hash of the files. If the comparison is false, the system requests a copy of the file from a server, which may be unknown or untrusted. The system then compares the received file to the stored hash. If the comparison is true, the copy of the file will be installed on the system. If false, the system repeats the request.
