摘要： Systems and methods are provided for encrypting data without regard to applications writing the data to, or reading the data from, encrypted data storage devices. An operating system intercept detects information indicating that a file will be encrypted and, in respond, sets device-level flags indicating encryption and also establishes one or more encryption keys to be used in the encryption process. A second intercept detects an input/output event and, in response, calls an encryption application to encrypt (or decrypt) the data before it is written to (or read from) the data storage device.

摘要： Systems and methods are provided for encrypting data, generating encryption keys, and generating encryption indicators. The encryption indicators may be stored on a storage medium in a location separate from the location of stored encrypted data. The encryption indicator includes information indicative of the encryption key used for encrypting and decrypting the data. In one example, the storage medium is a tape, and the encryption indicator is stored in the user header label of the tape.

摘要： The present invention is directed to a method and system for intercepting transactions for encryption. In accordance with a particular embodiment of the present invention, an application for a storage device is monitored. A transaction for the storage device is intercepted. An encryption request within the transaction is identified. Performance of the transaction is emulated by performing the encryption request in a predetermined exit point of the application.

摘要： A method is described for determining automatically, via a network protocol, a system topology of a network system, wherein the network system comprises a plurality of network components, wherein each of the network components support a directory protocol, and wherein the system topology comprises a respective address of each of the plurality of network components. The system topology is mapped via the directory protocol. Finally, a role-based access credential is configured for a user, via the directory protocol, wherein the role-based access credential determines which of the plurality of network components are accessible to the user.

摘要： A method includes identifying a first value of a lock word corresponding to a data structure, by a process in a plurality of processes that each have access to the data structure. The method also includes copying the data structure to a corresponding shadow record. The method additionally includes modifying the shadow record with a desired update for the data structure, and atomically updating the data structure and the lock word, by the process, using a hardware built-in function. The updating includes identifying a second value of the lock word and determining whether the first value of the lock word and the second value of the lock word are equivalent. The method additionally includes, in response to determining that the first value of the lock word and the second value of the lock word are equivalent, replacing the data structure with the shadow record and incrementing the lock word.

摘要： A method includes receiving, at a logical partition, a series of messages. Each message in the series of messages includes a respective block of data. The method further includes, in response to receiving the first message of the series of messages, suspending further processing of the series of messages. The method also includes identifying, from a header of the first message, a respective buffer address for each block of data. The method still further includes resuming processing of the series of messages. The method additionally includes, for each respective block of data, storing the respective block of data at the respective buffer address, and transferring the respective block of data from the corresponding buffer address to an open storage disk.
