| Abstract: | The current research in access control area and primary access control of Linux is firstly introduced.With the comparison and examples,the existing flaws about access control are discussed.On the basis of role-based access control(RBAC) and process-based access control(PBAC) of current operating system,a new mechanism called role-process-based access control(RPBAC) is presented,which is defined formally.The security of operating system is enhanced by the help of static and dynamic method.The task of follow ... |
