Privilege Exception Handling in Computer Systems
Handling privilege exceptions is an essential part of the operating system's security mechanism. Whenever a process attempts to execute an operation that requires higher privileges than its current permission level, a privilege exception is raised. The OS must handle this exception properly to prevent unauthorized access to system resources and ensure the system's stability.
Handling the Privilege Exception
The correct way of handling a privilege exception is as follows:
1. Exception Detection: Whenever a process attempts to execute an operation that requires higher privileges, the CPU generates a privilege exception.
2. Interrupt Handling: The OS receives the interrupt signal and switches the processor mode from user mode to kernel mode.
3. Exception Handling: The OS identifies the cause of the exception and takes appropriate action to handle it.
4. Process Restart: Once the privilege exception is handled, the OS restarts the interrupted process from where it left off.
5. Mode Switching: The OS switches the processor mode back to user mode and resumes the execution of the interrupted process.
Conclusion
In summary, a privilege exception is dealt with by interrupting the current process's execution, switching the processor mode from user mode to kernel mode, identifying the cause of the exception, taking appropriate action to handle it, restarting the interrupted process, switching the mode back to user mode, and resuming the execution of the interrupted process. This mechanism ensures that the system remains secure and stable and prevents unauthorized access to system resources.
