Table 12. BIOS Setup options—Security menu(continued)

Security Description

NOTE: When enabled, the computer will wipe data from all the internal drives

when a chassis intrusion is detected. This setting could cause data loss or

corruption.

Dell Technologies recommends keeping the Chassis Intrusion Data Wipe

option disabled.

Device Configuration Hotkey Access The OROM Keyboard Access feature allows you to enter the Option ROM

configuration screens, using hotkeys during the boot process. This setting

controls only the Intel RAID (CTRL+I), MEBX (CTRL+P), and LSI RAID (CTRL+C)

Option ROMs. Other preboot Option ROMs which support entry via a key

sequence are not affected by this setting.

For additional security, Dell Technologies recommends keeping the OROM

Keyboard Access option enabled.

Legacy Manageability Interface Access Allows the administrator to control the access to BIOS configuration through the

Legacy Manageability Interface option. When enabled, this prevents the BIOS

Administrator password-based manageability tools from running, prevents some

Dell software applications from reading configuration settings, and/or prevents

changes to the BIOS configuration settings.

When enabled, this option only supports the Authenticated BIOS Manageability

Interface (ABI) for managing the BIOS configuration changes. To support this

feature, ABI must be enabled and provisioned.

When set to Enabled, the Legacy Manageability Interface can be used to read

and change BIOS configuration settings.

When set to Read-Only, BIOS configuration settings can be read, but cannot be

changed through the Legacy Manageability Interface.

When set to Disabled, the Legacy Manageability Interface is disabled. BIOS

configuration reads and writes are blocked.

SMM Security Mitigation Enables or disables additional UEFI SMM Security Mitigation protections. This

option uses the Windows SMM Security Mitigations Table (WSMT) to confirm to

the operating system that security best practices have been implemented by the

UEFI firmware.

By default, the SMM Security Mitigation option is enabled.

For additional security, Dell Technologies recommends keeping the SMM

Security Mitigation option enabled unless you have a specific application which

is not compatible.

NOTE: This feature may cause compatibility issues or loss of functionality

with some legacy tools and applications.

Thunderbolt Security Level Thunderbolt Security Level gives you control to authenticate Thunderbolt

devices, when connected to the computer.

When set to User Authorization the computer will prompt you to allow each

Thunderbolt device that you connect to the computer.

NOTE: Thunderbolt devices may have access to read and write the

computer memory. You should only allow devices which you trust.

Dell Technologies recommends keeping the Thunderbolt Security Level option

User Authorization.

Disable USB4 PCIe Tunneling The Disable USB4 PCIe Tunneling option allows a system administrator to disable

the PCIe functionality of Thunderbolt ports.

When enabled, the Disable USB4 PCIe Tunneling option will prevent Thunderbolt

ports from operating in native TBT mode, and any attached PCIe devices will not

function (e.g. PCIe NIC).
