Development of New Cloud Information Gateway Technology for Inter-Cloud Data Security by Fujitsu
The currently available technologies for data security and information leaks include encryption and the blocking of the outflow of confidential data before it arrives at company’s external boundary, however in era of cloud computing, the boundary that separating internal and external data has becoming overwhelmingly blurred for apparent utilization of external services, making these type of services unemployable for the simple reason of blocking and encrypting classified data. In addition to this dilemma, it would be impossible for group of companies to securely use each other’s data in cloud computing environment.
In response to this technical challenge Fujitsu Laboratory has developed a new cloud information gateway technology capable of controlling data in a flexible manner, including data content, transmitted from inside of a company to a cloud as well as between multiple clouds. In addition to this capability, the new technology features data masking technology making confidential part of the data to be deleted or changed before the data are transmitted to an external cloud. The new technology comes with secure Logic Migration and Execution for confidential data that can not be released outside of the company, for concealing certain aspects of the data by simply defining the security level of data. Finally, the new inter-cloud data security technology features data traceability by tracking all the information flowing into and out of the cloud for checking the content of the data. The data traceability uses the logs obtained on data traffic as well as the characteristics of the related text to give visibility to the data being used in the cloud.
