Abstract

The present invention provides a method and apparatus for securing portions of a memory. The method includes identifying information for protection and indicating at least one physical address of a memory that houses the information as at least one of read and write disabled. The method includes receiving a request from a program to access the information. The method further includes accessing the information in response to determining that the program has the authority to access the information.
