# CIS 5.1 — Disable Intel Trusted Execution Technology (TXT)

## Profile Applicability

- Level 1

## Description

Intel Trusted Execution Technology (TXT) is a security-related CPU feature that is not currently leveraged by OpenShift or Openshift virtualization.

## Rationale

Neither OCP nor Openshift Virtualization leverage Trusted Execution Technology, which can be safely disabled.

## Impact

None.

## Audit Procedure

Use the following command to return the BIOS settings for a physical host:

```
$ fwupdmgr get-bios-settings
```

Look for `TxT`, and ensure the `Current value` is `Disabled`

## Remediation

Disable TXT via the firmware settings of each worker node.

## Default Value

The default value is firmware-dependent.

## References

None listed in the PDF.
