Which threat does Managed Device Attestation help protect against?

Managed Device Attestation primarily helps protect against private key extraction for use on a rogue device. This process ensures that a managed device is genuine and has not been tampered with, which is crucial when it comes to maintaining the integrity of cryptographic keys stored on the device. By verifying that a device is in a secure environment, Managed Device Attestation mitigates the risk of rogue devices attempting to extract sensitive private keys, which could be exploited to impersonate users or access restricted resources without authorization.

The correct answer reflects the ability of attestation mechanisms to confirm that the device running the application is actually the device intended to be used, thus reinforcing security against potential threats arising from compromised or untrusted devices. This is particularly important in enterprise environments where data security and device integrity are paramount.
