摘要
A system and method for dynamic security domain data protection through passive monitoring of data storage. The present invention may be implemented using data breakpoints to trigger invocation of the data flow analysis routines. A data breakpoint register may be associated with the memory location of each item of target data. Upon attempted access, a data breakpoint interrupt is triggered, which pauses execution and runs data flow analysis and security routines to determine the appropriate action. The present invention may be implemented using a virtual paging system having a memory management unit configured to generate a page fault upon any attempt to access target data. The virtual paging system may have a virtual page that contains target data and that page may be actively managed so that each attempted access to target data results in a page fault, which pauses execution and runs data flow analysis routines to determine appropriate action.
