Generate, store, and limit the use of cryptographic keys.Some of the advantages of using TPM technology are: The chip includes multiple physical security mechanisms to make it tamper-resistant, and malicious software is unable to tamper with the security functions of the TPM. A TPM chip is a secure crypto-processor that is designed to carry out cryptographic operations. The Trusted Platform Module (TPM) technology is designed to provide hardware-based, security-related functions. It can start because I have added our company cert to polocy file (also AI Cert) and before showing the first installer screen it fails with the policy message popup.Īlso I have noticed that using the Windows WDAC Wizard it adds certs also with issuing CA.This article describes the Trusted Platform Module (TPM) and how Windows uses it for access control and authentication. I have try first with the latest Windows 10 version and with the guide everything works well but with this Enterprise LTSB version using the same policy the installer is failing. I have followed all the steps and in this version of Windows the enable or diable policy are a little bit different, following microsoft docs with power shell I can enable or disable the policy successfully but the installer didn't work. I have a problem with this in Microsoft Windows 10 Enterprise 2016 LTSB OS Version: 3 N/A 14393 It was so helpful to understand how to configure Windows Device Guard policy. we will repeat step 1), this time for the Program Files folderĪfter the reboot, you should now be able to install the setup created with Advanced Installer. We will scan the Program Files folder separately, which will generate a second XML file, policyprogfiles.xml, that we can merge with policysys32.xml.Ģ. This should capture most files that Windows needs to boot and run. We restricted New-CIPolicy to scanning only the system32 folder. The -ScanPath parameter specifies the path to a directory that will be scanned for executables to include in the policy. The -UserPEs parameter specifies that the policy should apply to user-mode Portable Executable (PE) files, which are executable files that run in user mode, rather than kernel mode. The "Publisher" level allows code from trusted publishers to run, while the "System" level allows only code that is signed by Microsoft to run. The -Level parameter specifies the level of the policy, which can be either "Publisher" or "System". The -FilePath parameter specifies the path to the file where the policy will be saved. The New-CIPolicy cmdlet creates a new Code Integrity (CI) policy, which is a set of rules that define what code is allowed to run on a system. However, it's the configuration which is a bit more complicated at it requires some PowerShell knowledge. Turning on this policy is quite easy as you'll see in the following steps. the customer files) are signed with his own certificate.Īs previously mentioned, the solution would be to add both our certificate and the user's certificate to the policy, so that the setup becomes "trustworthy". Now, the issue our users encountered is the fact that some resources from the project (such as temporary fles, custom actions, etc.) are signed with our own certificate, while the resources from the setup (e.g. In today's article, since I familiarized myself with the topic, I will try to explain what this policy is and how to configure it as such you will be able to install the setup created with Advanced Installer there.ĭevice Guard is a policy that allows organizations to lock down devices in a way that provides advanced malware protection against new and unknown malware variants by blocking anything other than trusted apps- which are apps that are signed by specific software vendors, the Windows Store, or even your own organization. Recently, I've had a user not being able to install his setup created with Advanced Installer on a machine where the Code Integrity (Device Guard) policy was enabled.
