# About Certification Authorities

A CA is necessary if you want to configure any of these settings in an Intel AMT device:

- Remote Access
- Transport Layer Security
- 802.1x Setups
- End-Point Access Control

During configuration of these settings, Intel SCS sends a request to a CA software application to generate a certificate. Intel SCS puts the generated certificate in the Intel AMT device. Intel SCS can request certificates:

- From a Microsoft* CA – This is the default option.
- Using predefined files
