Table 6-3Computer Setup—Security (continued)

	System Security	Data Execution Prevention (enable/disable) - Helps prevent operating system security breaches.
	(these options are	Default is enabled.
	hardware dependent)	Virtualization Technology (VTx) (enable/disable) - Controls the virtualization features of the
		processor. Changing this setting requires turning the computer off and then back on. Default is
		disabled.
		Virtualization Technology Directed I/O (VTd) (enable/disable) - Controls virtualization DMA
		remapping features of the chipset. Changing this setting requires turning the computer off and then
		back on. Default is disabled.
		Trusted Execution Technology (enable/disable) - Controls the underlying processor and chipset
		features needed to support a virtual appliance. Changing this setting requires turning the computer
		off and then back on. Default is disabled. To enable this feature you must enable the following
		features:
		● Embedded Security Device Support
		● Virtualization Technology
		● Virtualization Technology Directed I/O
		Embedded Security Device (enable/disable) - Permits activation and deactivation of the Embedded
		Security Device.
		NOTE: To configure the Embedded Security Device, a Setup password must be set.
		● Reset to Factory Settings (Do not reset/Reset) - Resetting to factory defaults will erase all
		security keys and leave the device in a disabled state. Changing this setting requires that you
		restart the computer. Default is Do not reset.
		CAUTION: The embedded security device is a critical component of many security schemes.
		Erasing the security keys will prevent access to data protected by the Embedded Security
		Device. Choosing Reset to Factory Settings may result in significant data loss.
		● Measure boot variables/devices to PCR1 - Typically, the computer measures the boot path and
		saves collected metrics to PCR5 (a register in the Embedded Security Device). Bitlocker tracks
		changes to any of these metrics, and forces the user to re-authenticate if it detects any
		changes. Enabling this feature lets you set Bitlocker to ignore detected changes to boot path
		metrics, thereby avoiding re-authentication issues associated with USB keys inserted in a port.
		Default is enabled.
		OS management of Embedded Security Device (enable/disable) - This option allows the user to limit
		OS control of the Embedded Security Device. Default is
		● Reset of Embedded Security Device through OS (enable/disable) - This option allows the user
		to limit the operating system ability to request a Reset to Factory Settings of the Embedded
		Security Device. Default is disabled.
		NOTE: To enable this option, a Setup password must be set.
		● No PPI provisioning (Windows 8 only) - This option lets you set Windows 8 to bypass the PPI
		(Physical Presence Interface) requirement and directly enable and take ownership of the TPM
		on first boot. You cannot change this setting after TPM is owned/initialized, unless the TPM is
		reset. Default is disabled for non-Windows 8 systems, and enabled for Windows 8.
		● Allow PPI policy to be changed by OS. Enabling this option allows the operating system to
		execute TPM operations without Physical Presence Interface. Default is disabled.
		NOTE: To enable this option, a Setup password must be set.
		Button Retask Password Protection (disable/enable) - Controls whether or not the Setup password
		must be provided to WMI methods used to re-task the function of the side panel buttons.
