Abstract
Methods and systems for content filtering of remote file-system access protocols are provided. According to one embodiment, a proxy, implemented within a network gateway device of a private network, monitors remote file-system access protocol sessions involving client computer systems and a server computer system associated with the private network. For each file on a share of the server computer system being accessed by one or more of the client computer systems: (i) a shared holding buffer corresponding to the file is created within a shared memory of the network gateway device; (ii) data being read from or written to the file by the monitored remote file-system access protocol sessions is buffered into the shared holding buffer; and (iii) responsive to a predetermined event, content filtering is performed on the shared holding buffer to determine whether malicious, dangerous or unauthorized content is contained within the shared holding buffer.
