System Security Settings details
The System Security Settings screen details are explained as follows:
Option Description
CPU AES-NI Improves the speed of applications by performing encryption and decryption by using the Advanced Encryption
Standard Instruction Set (AES-NI). This option is set to Enabled by default.
System Password Enables you to set the system password. This option is set to Enabled by default and is read-only if the password
jumper is not installed in the system.
Setup Password Enables you to set the system setup password. This option is read-only if the password jumper is not installed in
the system.
Password Status Enables you to lock the system password. This option is set to Unlocked by default.
TPM Security
Enables you to control the reporting mode of the TPM. The TPM Security option is set to Off by default. You can
only modify the TPM Status TPM Activation, and the Intel TXT fields if the TPM Status field is set to either On
with Pre-boot Measurements or On without Pre-boot Measurements.
TPM Information Enables you to change the operational state of the TPM. This option is set to No Change by default.
TPM Status Specifies the TPM status.
TPM Command Controls the Trusted Platform Module (TPM). When set to None, no command is sent to the TPM. When set to
Activate, the TPM is enabled and activated. When set to Deactivate, the TPM is disabled and deactivated. When
set to Clear, all the contents of the TPM are cleared. This option is set to None by default.
This field is read-only when TPM Security is set to Off. The action requires an additional reboot before it can take
effect.
TPM Advanced This setting is enabled only when TPM Security is set to ON.
Settings
Intel(R) TXT Enables you to set the Intel Trusted Execution Technology (TXT) option. To enable the Intel TXT option,
virtualization technology and TPM Security must be enabled with Pre-boot measurements. This option is set to Off
by default.
Power Button Enables you to set the power button on the front of the system. This option is set to Enabled by default.
AC Power Recovery Sets how the system behaves after AC power is restored to the system. This option is set to Last by default.
AC Power Recovery Enables you to set the time that the system should take to power up after AC power is restored to the system.
Delay This option is set to Immediate by default.
User Defined Delay Enables you to set the User Defined Delay option when the User Defined option for AC Power Recovery Delay is
(60 s to 240 s) selected.
UEFI Variable Provides varying degrees of securing UEFI variables. When set to Standard (the default), UEFI variables are
Access accessible in the operating system per the UEFI specification. When set to Controlled, selected UEFI variables are
protected in the environment, and new UEFI boot entries are forced to be at the end of the current boot order.
In-Band When set to Disabled, this setting will hide the Management Engine's (ME), HECI devices, and the system's IPMI
Manageability devices from the operating system. This prevents the operating system from changing the ME power capping
Interface settings, and blocks access to all in-band management tools. All management should be managed through out-of-
band. This option is set to Enabled by default.
NOTE: The TPM menu is available only when the TPM module is installed.
CAUTION: Clearing the TPM results in the loss of all keys in the TPM. The loss of TPM keys may affect
booting to the operating system.
NOTE: BIOS update requires HECI devices to be operational and DUP updates require IPMI interface to
be operational. This setting needs to be set to Enabled to avoid updating errors.
