By using code integrity policies, an enterprise can also select exactly which binaries can run in both user mode and kernel mode. Simply by deploying code integrity policies, organizations can get immediately protection against unsigned malware, which is estimated to be responsible for the majority of current attacks. Historically, most malware has been unsigned. For more details of Group Policy configuration, seeĭeploy configurable code integrity policy It is recommended to enable HVCI on all the servers running Windows Server 2016. HVCI (a.k.a Virtualization Based Security of Code Integrity) can be deployed using Group Policy.

Kernel mode drivers signed and compatible with hypervisor-enforced code integrity UEFI configured to prevent an unauthorized user from disabling Device Guard–dependent hardware security features (for example, Secure Boot) Virtualization extensions (for example, Intel VT-x, AMD RVI) Virtualization support enabled by default in the system firmware: UEFI Secure Boot (optionally with non-Microsoft UEFI CAs removed from the UEFI database)

To deliver this level of security, Device Guard has the following hardware and software requirements: By forcing memory into these states, it helps ensure that attacks are unable to inject malicious code into kernel mode processes and drivers through techniques such as buffer overruns or heap spraying. This means that after memory has been allocated, its state must be changed from writable to read only or execute only. HVCI uses the processor’s functionality to force all software running in kernel mode to safely allocate memory. Devices that have processors equipped with SLAT technologies and virtualization extensions, such as Intel VT x and AMD V, will be able to take advantage of a Virtualization Based Security (VBS) environment that dramatically enhances Windows security by isolating critical Windows services from the operating system itself.ĭevice Guard leverages VBS to isolate its Hypervisor Code Integrity (HVCI) service, which enables Device Guard to help protect kernel mode processes and drivers from vulnerability exploits and zero days. The core functionality and protection of Device Guard starts at the hardware level. Requirements for deployment planning for Device GuardĮnhanced Kernel Mode protection using Hypervisor Code Integrity (HVCI) Device Guard also provides user mode protection (UMCI), where you can create Code Integrity (CI) policies which defines what’s trusted and authorized to run on individual servers.įor details on Device Guard, here are some good references (not a complete list):

If there is a comprised driver which tries to modify code in memory, it cannot be executed on the machine. Device Guard will block drivers from loading dynamic code and block any driver that is not on the whitelist. Under Kernel mode protection, Device Guard ensures the drivers are, at the very least, signed by a known signature (WHQL signed) or you can further restrict the drivers by whitelisting them in the policy. We need both mechanisms, depending on how sensitive the information is to be protected.ĭevice Guard can protect software running in Kernel mode and User mode. In my mind, antivirus software is like the police which catch bad apps if they made their name on the list whereas Device Guard is like a vault, which allows you to create a secure environment which allows only the apps you trust to enter. Device Guard on Windows Server 2016 changes from a mode where apps are trusted unless blocked by an antivirus or other security solution, to a mode where the operating system trusts only apps authorized by your enterprise.
