-(Recommended) The first option is to keep the deny list as its own policy isolated from your allow policies as it is easier to manage. Since applications need to be allowed by both WDAC policies to run on the device [Use multiple Windows Defender Application Control Policies (Windows) - Windows security | Microsoft Docs](https://docs.microsoft.com/en-us/windows/security/threat-protection/windows-defender-application-control/deploy-multiple-windows-defender-application-control-policies#base-and-supplemental-policy-interaction), you will need to add the Allow All rule(s) to your deny policy.

This will not override the set of applications allowed by WDAC illustrated by the following example:
 
 Policy 1 is an allow list of Windows and Microsoft-signed applications. Policy 2 is our new deny policy which blocks MaliciousApp.exe with the Allow All rules. MaliciousApp.exe will be blocked since there is an explicit block rule in Policy 2. Windows and Microsoft applications will be allowed since there is an explicit allow rule in Policy 1 and Policy 2 (due to the Allow All rules). All other applications, if not Windows and Microsoft signed, e.g., ExampleApp.exe, will not be allowed as this application is only trusted by Policy 2 (due to the Allow All rules) and not Policy 1.
 
 ## Best Practices
 
-1. **Starting with Audit Mode Policies** - as with all new policies, we recommend rolling out your new deny policy in Audit Mode and monitoring the 3077 block events [Understanding Application Control event IDs (Windows) - Windows security | Microsoft Docs](https://docs.microsoft.com/en-us/windows/security/threat-protection/windows-defender-application-control/event-id-explanations#microsoft-windows-codeintegrity-operational-log-event-ids) to ensure only the applications you intended to block are being blocked.

 2. **Recommeneded Deny Rules Types** - signer and file attribute rules are recommended from a security, manageability, and performance perspective. Hash rules should only be utilized where otherwise impossible. The hash of an application is updated for every new version released by the publisher which quickly becomes impractical to manage and protect against new threats where the attacker is quickly iterating on the payload. Additionally, WDAC has optimized parsing of hash rules, but devices may see performance impacts at runtime evaluation when policies have tens of thousands or more hash rules.
