SECURE NETWORK FILE ACCESS CONTROL SYSTEM

摘要

A secure network file access appliance (12) supports the secure access and transfer of data between the file system (34) of a client computer system (22) and a network data store (16). An agent (36) provided on the client computer system and monitored by the secure network file access applicance ensures authentication of the client computer system with respect to file system requests issued to the network data store. The secure network file access appliance is provided in the network infrastructure between the client computer system and network data store to apply qualifying access polices and selectively pass through to file system requests. The secure ntwork file access appliance maintains an encryption key store and associates encryption keys with corresponding filesystem files to encrypt and decrypt file data as transferred to and read from the network data store thorugh the secure network file access appliance.
