摘要:
A method for storing data in which the data to be stored is divided into a plurality of source blocks, each source block subjected to steps including defining a block key for the source block based on a random function, encrypting the source block by utilizing the defined block key, selecting at least one first storage location and one second storage location from a plurality of different available storage locations, storing control data that includes information on the defined block key at the first selected storage location, and storing encrypted data that includes information on the encrypted source block at the second selected storage location.
摘要:
A computer security method includes receiving a security alert associated with an electronic attack to at least one computer system of a data network, identifying a first set of business services which may be affected by the electronic attack, estimating, based on an identified first set of potentially affected business services, a first potential cost to a business when the electronic attack is successful, identifying at least one counteraction which may be employed to prevent or mitigate the electronic attack, identifying a second set of business services which may be affected by the at least one counteraction, estimating, based on the identified second set of potentially affected business services, a second potential cost to the business when the counteraction is employed, and comparing the first potential cost and the second potential cost.
