Abstract
Official abstract text for this publication.
Extensions to the Fragment Mapping Protocol are introduced which protect a disk array from malicious client access by exporting file system access information to the storage device. FMP requests received at the storage device can be authorized at a block granularity prior to completion, thereby limiting the exposure of the disk array to malicious clients. Client authorizations can be cached at the storage device to enable the permissions to be quickly extracted for subsequent client accesses to pre-authorized volumes.
First claim
Opening claim text (preview).
The invention claimed is: 1. A file server for serving a file system, the file server comprising: an interface configured to receive a query from a storage device to validate a request made by a client device to access a file from the storage device, the query including a user identifier and a file location associated with the file access request; and a non-transitory computer usable medium having a computer readable program code, said computer readable program code including:…
