Typically, deployment of Windows Defender Application Control (WDAC) happens best in phases, rather than being a feature that you simply “turn on.” The choice and sequence of phases depends on the way various computers and other devices are used in your organization, and to what degree IT manages those devices. The following table can help you begin to develop a plan for deploying WDAC in your organization. It is common for organizations to have device use cases across each of the categories described.

### Catalog files
Catalog files (which you can create in Windows 10 with a tool called Package Inspector) contain information about all deployed and executed binary files associated with your trusted but unsigned applications. When you create catalog files, you can also include signed applications for which you do not want to trust the signer but rather the specific application. After creating a catalog, you must sign the catalog file itself by using enterprise public key infrastructure (PKI), or a purchased code signing certificate. Then you can distribute the catalog, so that your trusted applications can be handled by WDAC in the same way as any other signed application.

Catalog files are simply Secure Hash Algorithm 2 (SHA2) hash lists of discovered binaries. These binaries' hash values are updated each time an application is updated, which requires the catalog file to be updated also.
After you have created and signed your catalog files, you can configure your WDAC policies to trust the signer or signing certificate of those files.

## Windows Defender Application Control policy formats and signing
When you generate a WDAC policy, you are generating a binary-encoded XML document that includes configuration settings for both the User and Kernel-modes of Windows 10 Enterprise, along with restrictions on Windows 10 script hosts. You can view your original XML document in a text editor, for example if you want to check the rule options that are present in the **&lt;Rules&gt;** section of the file.
When you generate a WDAC policy, you are generating a binary-encoded XML document that includes configuration settings for both the User and Kernel-modes of Windows 10 and Windows 11 Enterprise, along with restrictions on Windows 10 and Windows 11 script hosts. You can view your original XML document in a text editor, for example if you want to check the rule options that are present in the **&lt;Rules&gt;** section of the file.
We recommend that you keep the original XML file for use when you need to merge the WDAC policy with another policy or update its rule options. For deployment purposes, the file is converted to a binary format, which can be done using a simple Windows PowerShell command.

When creating policies for use with Windows Defender Application Control (WDAC), it is recommended to start with a template policy and then add or remove rules to suit your application control scenario. For this reason, the WDAC Wizard offers three template policies to start from and customize during the base policy creation workflow. Prerequisite information about application control can be accessed through the [WDAC design guide](windows-defender-application-control-design-guide.md). This page outlines the steps to create a new application control policy from a template, configure the policy options, and the signer and file rules.

Beginning in Windows 10 version 1903, WDAC supports the creation of multiple active policies on a device. One or more supplemental policies allow customers to expand a [WDAC base policy](wdac-wizard-create-base-policy.md) to increase the circle of trust of the policy. A supplemental policy can expand only one base policy, but multiple supplementals can expand the same base policy. When using supplemental policies, applications allowed by the base or its supplemental policy/policies will be allowed to execute.
Prerequisite information about application control can be accessed through the [WDAC design guide](windows-defender-application-control-design-guide.md). This page outlines the steps to create a supplemental application control policy, configure the policy options, and the signer and file rules.

This guide covers design and planning for Windows Defender Application Control (WDAC). It is intended to help security architects, security administrators, and system administrators create a plan that addresses specific application control requirements for different departments or business groups within an organization.
## Plan for success
A common refrain you may hear about application control is that it is "too hard". While it is true that application control is not as simple as flipping a switch, organizations can be very successful if they take a methodical approach and carefully plan their approach. In reality, the issues that lead to failure with application control often arise from business issues rather than technology challenges. Organizations that have successfully deployed application control have ensured the following before starting their planning:
A common refrain you may hear about application control is that it is "too hard". While it is true that application control is not as simple as flipping a switch, organizations can be successful if they take a methodical approach and carefully plan their approach. In reality, the issues that lead to failure with application control often arise from business issues rather than technology challenges. Organizations that have successfully deployed application control have ensured the following before starting their planning:
- Executive sponsorship and organizational buy-in is in place.
- There is a clear **business** objective for using application control and it is not being planned as a purely technical problem from IT.
- The organization has a plan to handle potential helpdesk support requests for users who are blocked from running some apps.
- The organization has considered where application control can be most useful (e.g. securing sensitive workloads or business functions) and also where it may be difficult to achieve (e.g. developer workstations).
