Prevent attackers from obtaining access to minimize potential damage to data and systems. Protect privileged roles, verify end-to-end encryption, use analytics to get visibility, and drive threat detection to improve defenses. The Zero Trust concept of verify explicitly applies to the risks introduced by both devices and users. Windows enables device health attestation and conditional access capabilities, which are used to grant access to corporate resources.
Conditional access evaluates identity signals to confirm that users are who they say they are before they're granted access to corporate resources. Windows 11 supports device health attestation, helping to confirm that devices are in a good state and haven't been tampered with.
Attestation helps verify the identity and status of essential components and that the device, firmware, and boot process haven't been altered. Information about the firmware, boot process, and software, is used to validate the security state of the device.
Once the device is attested, it can be granted access to resources. Many security risks can emerge during the boot process as this process can be the most privileged component of the whole system. Remote attestation determines:. Devices can attest that the TPM is enabled, and that the device hasn't been tampered with.
Windows includes many security features to help protect users from malware and attacks. However, trusting the Windows security components can only be achieved if the platform boots as expected and wasn't tampered with. When you power on your PC until your anti-malware starts, Windows is backed with the appropriate hardware configuration to help keep you safe.
Measured and Trusted boot , implemented by bootloaders and BIOS, verifies and cryptographically records each step of the boot in a chained manner. Remote Attestation is the mechanism by which these events are read and verified by a service to provide a verifiable, unbiased, and tamper resilient report. Remote attestation is the trusted auditor of your system's boot, allowing specific entities to trust the device.
During each step of the boot process, such as a file load, update of special variables, and more, information such as file hashes and signature are measured in the TPM PCRs.
The measurements are bound by a Trusted Computing Group specification TCG that dictates what events can be recorded and the format of each event. The measurements in both these components together form the attestation evidence that is then sent to the attestation service.

In response to historic attacks like Spectre and Meltdown, Windows 11 includes the successor to the memory integrity feature known as hypervisor-protected code integrity. HVCI, enabled by default, virtualizes memory and processes data in silos. Virtualizing and segmenting memory allows devices to adhere to the zero-trust model by executing instructions in complete isolation.
Administrators may control this feature via a registry key. Secure Boot creates a digital signature that prevents malicious binaries from executing on boot.
