![]() When implementing MDAC, it will tap into the Intelligent Security Graph (ISG), which is Microsoft’s threat analytics data which helps to classify if an application has a good reputation. Use AppLocker to granularly fine-tune the restrictions.’.Enforce WDAC at the most restrictive, least privilege level. ![]() As a best practice, Microsoft recommends that admins: However, AppLocker can be used effectively to compliment WDAC, to allow the usage of different policies per user on the same device. A key difference is that AppLocker does not offer the chain of trust, from the hardware to the kernel, that WDAC offers. AppLocker also enables you to control which applications and files can run on your system. WDAC works in-conjunction with Secure Boot, to ensure that boot binaries and the UEFI firmware are signed and have not been tampered with.Ī common misconception is that WDAC is an AppLocker replacement. It also hardens the operating system against kernel memory attacks using virtualization-based protection of code integrity (HVCI). CI guarantees that only the trusted code runs from the boot loader onwards. WDAC restricts application usage via a feature called configurable code integrity (CI). Applications or drivers need to be specified as trustworthy, which reduces the threat of executable based malware significantly. ‘WDAC, allows you to control your Windows 10 devices by creating policies that define whether a specific driver or application can be executed on a device. I wrote about MDAC back in the WDAC days for Adaptiva here’s the quote from that article at Simplifying Windows Defender Application Control with ConfigMgr & Intune Microsoft Defender Application Control (MDAC) started off as Device Guard, then became Windows Defender Application Control and is now Microsoft Defender Application Control – try and keep up! ![]() Exception.In this latest addition to the Keep it Simple with Intune series, I will implement Microsoft Defender Application Control policies to lock down the application estate to trusted apps. Write-Warning -Message "Failed to get Applocker extended info because $ ( $_. RuleCollections | Select-Object -Property * Write-Verbose 'Successfully read piped Applocker policy ' $data = Get-AppLockerPolicy -Local 'Successfully read local Applocker policy ' $data = Get-AppLockerPolicy -Effective 'Successfully read effective Applocker policy ' If we want to keep to local policy to apply, an explicit deny can be set to so that the computer stops applying the Audit only GPO. In the above specific example, we can see the local policy is Enforced with a few rules (probably default rules) and is stricter than the AD policy that is set to Audit Only. Here’s an example when there’s an overlap on Applocker policies: Using both the Effective and Local switches, it can help you diagnose how enforcement is configured if you’ve more than a local policy. Get-AppLockerPolicy -Ldap "LDAP://$(($gpo).path)" -Domain | $gpo = Get-GPO -All | Out-GridView -OutputMode Single ![]() In this case, I’ll use the cmdlets from the GroupPolicy module. It can be used to view the configuration in an Active Directory based Applocker policy. In other words it can be bound with the built-in Applocker cmdlets: It accepts also a policy object sent into the pipeline. Get-AppLockerPolicyInfo -Local | Format-Table -AutoSize You can also use the Local switch to view the local policy configuration: It can be used without parameters and will display the Effective policy I’ve created a function to view the above settings. Rule collections can be “not configured” or when they are “configured”, they can be set to “enforced” or “audit only”. When you edit an Applocker Group Policy either a local one or one stored in Active Directrory, you can view and configure what collections are active and what these should do.
