    • When providing a user with native access to at least a portion of device hardware, the user can be prevented from modifying firmware and other configuration information by controlling the mechanisms used to update that information. In some embodiments, an asymmetric keying approach can be used to encrypt or sign the firmware. In other cases access can be controlled by enabling firmware updates only through a channel or port that is not exposed to the customer, or by mapping only those portions of the hardware that are to be accessible to the user. In other embodiments, the user can be prevented from modifying firmware by only provisioning the user on a machine after an initial mutability period wherein firmware can be modified, such that the user never has access to a device when firmware can be updated. Combinations and variations of the above also can be used.
    • 当向用户提供对至少一部分设备硬件的本地访问时,可以通过控制用于更新该信息的机制来阻止用户修改固件和其他配置信息。 在一些实施例中,可以使用非对称密钥方法来加密或签名固件。 在其他情况下,只能通过不暴露给客户的通道或端口启用固件更新,或仅映射用户可访问的硬件部分来控制访问。 在其他实施例中,可以通过在可修改固件的初始可变性周期之后仅在机器上提供用户来防止用户修改固件,使得当固件可以被更新时,用户永远不能访问设备。 上述的组合和变化也可​​以使用。

    • In an environment such as a cloud computing environment where various guests can be provisioned on a host machine or other hardware device, it can be desirable to prevent those users from rebooting or otherwise restarting the machine or other resources using unauthorized information or images that can be obtained from across the network. A cloud manager can cause one or more network switches or other routing or communication processing components to deny communication access between user-accessible ports on a machine or device and the provisioning systems, or other specific network resources, such that the user cannot cause the host machine to pull information from those resources upon a restart or reboot of the machine. Further, various actions can be taken upon a reboot or attempted reboot, such as to isolate the host machine or even power off the specific machine.
