MANDATORY PROCESS MEMORY ACCESS CONTROL METHOD USING MULTI-LEVEL SECURITY, AND COMPUTER READABLE RECORDING MEDIUM HAVING THEREON PROGRAMMED MANDATORY PROCESS MEMORY ACCESS CONTROL METHOD USING MULTI-LEVEL SECURITY

摘要

PURPOSE: A compulsory process memory access control method and a recording media read by a computer controlling access to process memory are provided to protect the leakage of process memory information by the other process with a security grade. CONSTITUTION: A mandatory process memory access control method based on a security grade mode is as follows. The security grade and category information about an application program which is installed in the system are distributed and set up(S10). When the process is generated while executing the application program within system, a field is allocated to a process structure body(S20). The secrecy level and the category information set up in the corresponding application are included. A main body accesses the process memory of an object the dissimilar process by an object.
