Abstract: Virtual machine introspection technology is a kind of technology that monitors the operating system and the operating status of the virtual machine from outside the virtual machine. The technology is less expensive and more secure because it does not require agents to be installed inside the virtual machine. In this paper, a virtual machine introspection technology based on system call interception is proposed, which intercepts the system calls that occur within the virtual machine by adjusting the response mechanism of VMM to system calls, and by analyzing system calls, the purpose of monitoring abnormal behavior state within the virtual machine is achieved.
