Device certificates used with an individual enrollment entry have a requirement that the issuer and subject CN are set to the device ID.

 - **Trusted Platform Module (TPM) attestation:** A [TPM](../../iot-dps/concepts-tpm-attestation.md) is a type of hardware security module. Using a TPM is one of the most secure ways to connect a device. This article assumes you're using a discrete, firmware, or integrated TPM. Software emulated TPMs are well suited for prototyping or testing, but they don't provide the same level of security as discrete, firmware, or integrated TPMs. Don't use software TPMs in production. To create an individual enrollment that uses a TPM, open the **Device Connection** page, select **Individual enrollment** as the connection method, and **TPM** as the mechanism. Enter the TPM endorsement key and save the device connection information.
