System Security Settings details
The System Security Settings screen provides the following options.
Option Description
In-Band
Manageability
Interface
When set to Disabled, this setting will hide the Management Engine's (ME), HECI devices, and the
system's IPMI devices from the operating system. This prevents the operating system from changing the
ME power capping 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: 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.
Intel(R) 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
Sets 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 Sets the setup password. This option is read-only if the password jumper is not installed in the system.
Password Status Locks the system password. This option is set to Unlocked by default.
TPM Security
NOTE: The TPM menu is available only when the TPM module is installed.
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 SGX fields if the TPM Status
field is set to either On with Pre-boot Measurements or On without Pre-boot Measurements.
When TPM 1.2 is installed, the TPM Security option is set to Off, On with Pre-boot Measurements,
or On without Pre-boot Measurements.
When TPM 2.0 is installed, the TPM Security option is set to On or Off. This option is set to Off by
default.
Intel(R) TXT Enables or disables 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.
When TPM 2.0 is installed, TPM 2 Algorithm option is available. It enables you to select a hash algorithm
from those supported by the TPM (SHA1, SHA256). TPM 2 Algorithm option must be set to SHA256,
to enable TXT.
Power Button Enables or disables 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 Delay
Sets the time delay for the system to power up after AC power is restored to the system. This option is
set to Immediate by default.
User Defined
Delay (60 s to
240 s)
Sets the User Defined Delay option when the User Defined option for AC Power Recovery Delay is
selected.
UEFI Variable
Access
NOTE: The NX3340 system does not support UEFI mode. This option cannot be used.
Provides varying degrees of securing UEFI variables. When set to Standard (the default), UEFI variables
are 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.
Secure Boot Enables Secure Boot, where the BIOS authenticates each pre-boot image by using the certificates in the
Secure Boot Policy. Secure Boot is set to Disabled by default.
Secure Boot
Policy
When Secure Boot policy is set to Standard, the BIOS uses the system manufacturers key and
certificates to authenticate pre-boot images. When Secure Boot policy is set to Custom, the BIOS uses
the user-defined key and certificates. Secure Boot policy is set to Standard by default.
