    摘要: Managing data units by converting the data units into data segments and access files describing how to retrieve the data segments using hash values for the data segments. In a data store operation, the data unit is divided into data segments and an access file is generated. The access file includes segmenting scheme information for the data segments, hashing scheme information for the hash values, hash identification information describing the hash values, and location information identifying the locations at which the data segments are available. In a data retrieval operation, data from the data unit is retrieved by accessing the data segments and extracting the data therefrom, where the data segments are retrieved based on the access file for the data unit.

    摘要: A method and system for obscuring user requests for information in a computer network. A user request for information, aimed at another network member, is routed to a first cache memory. If the first cache memory contains the requested information, the cache returns the requested information in response to the user request without releasing the user request to the network member. If the first cache memory does not contain the requested information, a first reference editing function edits user identity information contained in the request, resulting in an edited request with obscured identity information. The edited request is then released to the network member and the requested information is received by the user from the network member. A copy of the requested information is stored in the first cache memory. In this method and system, user privacy is enhanced because user requests for information that can be satisfied by information stored in the cache memory are not revealed to other network members, and user requests that cannot be satisfied by the cache memory are obscured by the reference editing function prior to release to other network members. A software program and system for implementing the method are also disclosed.

    摘要: Monitoring integrity of a running computer system is based on creating a Test Model which includes predicates descriptive of invariant properties of security relevant objects and their attributes in the monitored structure known-to-be “healthy”, acquiring memory image of a portion of the running monitored structure, decomposing the acquired memory image to retrieve representation of the security relevant objects of interest, by implementing the attributes of the Test Model, and verifying, by implementing the predicates, whether the invariant properties defined in the Test Model remain unchanged for the running host system. If a discrepancy is detected, a signal indicative of a detected discrepancy is transmitted to a management entity for analysis and formulating a course of action.

    摘要: A network-based storage system comprises one or more block-level storage servers that connect to, and provide disk storage for, one or more host computers (“hosts”) over logical network connections (preferably TCP/IP sockets). In one embodiment, each host can maintain one or more socket connections to each storage server, over which multiple I/O operations may be performed concurrently in a non-blocking manner. The physical storage of a storage server may optionally be divided into multiple partitions, each of which may be independently assigned to a particular host or to a group of hosts. Host driver software presents these partitions to user-level processes as one or more local disk drives. When a host initially connects to a storage server in one embodiment, the storage server initially authenticates the host, and then notifies the host of the ports that may be used to establish data connections and of the partitions assigned to that host.
