Security Description

Trusted Platform Module (TPM) The Trusted Platform Module (TPM) provides various cryptographic services

which serve as the cornerstone for many platform security technologies. Trusted

Platform Module (TPM) is a security device that stores computer-generated

keys for encryption and features such as BitLocker, Virtual Secure Mode, remote

Attestation.

By default, the Trusted Platform Module (TPM) option is enabled.

For additional security, Dell Technologies recommends keeping Trusted

Platform Module (TPM) enabled to allow these security technologies to fully

function.

NOTE: The options that are listed apply to computers with a discrete

Trusted Platform Module (TPM) chip.

TPM On Allows you to enable or disable TPM.

By default, the TPM On option is enabled.

For additional security, Dell Technologies recommends keeping TPM On enabled

to allow these security technologies to fully function.

Physical Presence Interface (PPI) Bypass The Physical Presence Interface (PPI) Bypass options can be used to allow

the operating system to manage certain aspects of the TPM. If these options

are enabled, you are not prompted to confirm certain changes to the TPM

configuration.

For additional security, Dell Technologies recommends keeping the PPI Bypass

for Enable Commands option enabled.

For additional security, Dell Technologies recommends keeping the PPI Bypass

for Disable Commands option disabled.

For additional security, Dell Technologies recommends keeping the PPI Bypass

for Clear Commands option disabled.

Attestation Enable The Attestation Enable option controls the endorsement hierarchy of the TPM.

Disabling the Attestation Enable option prevents TPM from being used to

digitally sign certificates.

By default, the Attestation Enable option is enabled.

For additional security, Dell Technologies recommends keeping the Attestation

Enable option enabled.

NOTE: When disabled, this feature may cause compatibility issues or loss of

functionality in some operating systems.

Key Storage Enable The Key Storage Enable option controls the storage hierarchy of TPM, which is

used to store digital keys. Disabling the Key Storage Enable option restricts the

ability of TPM to store owner's data.

By default, the Key Storage Enable option is enabled.

For additional security, Dell Technologies recommends keeping the Key Storage

Enable option enabled.

NOTE: When disabled, this feature may cause compatibility issues or loss of

functionality in some operating systems.

SHA-256 Enables selection of the hashing algorithm that is used by the TPM. When

enabled, the TPM uses the SHA-256 hashing algorithm. When disabled, the TPM

uses the SHA-1 hash algorithm.

By default, the SHA-256 option is enabled.

For additional security, Dell Technologies recommends keeping the SHA-256

option enabled.
