摘要:
A virtual machine monitoring method used in a virtual machine monitoring system is provided. The virtual machine monitoring method includes retrieving a hypercall transmitted from one of a plurality of virtual machines to a hypervisor of a virtual machine monitoring system, wherein the hypercall is used for establishing a channel between a source virtual machine and a target virtual machine. A central control virtual machine ID information in the hypervisor is retrieved. A type of the channel established by the hypercall is determined according to the central control virtual machine ID information and channel-establishing information corresponding to the hypercall. When the channel is a private channel that is not related to a central control virtual machine of the virtual machines, a security module is used to monitor the private channel.

A monitor method and a monitor apparatus for monitoring a data of hardware are provided. The data has private information, identification information and at least one first network transmission address. The monitor apparatus comprises a storage unit and a processing unit. The data is stored in the storage unit according to the identification information. The processing unit is configured to record the identification information and the at least one first network transmission address of the data in a mark information table. In response to a sending system call, when a transmission is arranged to transmit the private information of the data to a second network transmission address which is different from the at least one first network transmission address, the processing unit will output a signal to cease the transmission.

An information security protection host is provided. The information security protection host comprises a network interface and a virtual machine monitor (VMM) device. The network interface is connected to a computer network and is configured to receive a first packet. The VMM device is configured to run a first operating system, wherein the first operating system provides a first network service. The VMM device is further configured to provide a first operating system information of the first operating system and a first network service information of the first network service instantaneously so as to determine the security of the first packet.
