# Customize Attack Surface Reduction
**Applies to:**
- Windows 10 Insider Preview
**Audience**
- Enterprise security administrators
**Manageability available with**
- Windows Defender Security Center app
- Group Policy
- PowerShell
- Configuration service providers for mobile device management
Attack Surface Reduction is a feature that is part of Windows Defender Exploit Guard. It helps prevent actions and apps that are typically used by exploit-seeking malware to infect machines.
This topic describes how to customize Attack Surface Reduction by [excluding files and folders](#exclude-files-and-folders) or [adding custom text to the notification](#customize-the-notification) alert that appears on a user's computer.
You can use Group Policy, PowerShell, and MDM CSPs to configure these settings.
## Exclude files and folders
You can exclude files and folders from being evaluated by Attack Surface Reduction rules.
You can specify individual files or folders (using folder paths or fully qualified resource names) but you cannot specify if the exclusions should only be applied to individual rules: the exclusions will apply to all rules that are enabled (or placed in audit mode).
### Use Group Policy to exclude files and folders
1. On your Group Policy management machine, open the [Group Policy Management Console](https://technet.microsoft.com/library/cc731212.aspx), right-click the Group Policy Object you want to configure and click **Edit**.
3. In the **Group Policy Management Editor** go to **Computer configuration**.
4. Click **Policies** then **Administrative templates**.
5. Expand the tree to **Windows components > Windows Defender Antivirus > Windows Defender Exploit Guard > Attack Surface Reduction**.
6. Double-click the **Exclude files and paths from Attack Surface Reduction Rules** setting and set the option to **Enabled**. Click **Show** and enter each file or folder in the **Value name** column. Enter **0** in the **Value** column for each item.
### Use PowerShell to exclude files and folderss
1. Type **powershell** in the Start menu, right click **Windows PowerShell** and click **Run as administrator**
2. Enter the following cmdlet:
```PowerShell
Add-MpPreference -AttackSurfaceReductionOnlyExclusions "<fully qualified path or resource>"
```
Continue to use `Add-MpPreference -AttackSurfaceReductionOnlyExclusions` to add more folders to the list.
>[!IMPORTANT]
>Use `Add-MpPreference` to append or add apps to the list. Using the `Set-MpPreference` cmdlet will overwrite the existing list.
### Use MDM CSPs to exclude files and folders
Use the [./Vendor/MSFT/Policy/Config/Defender/AttackSurfaceReductionOnlyExclusions](https://docs.microsoft.com/en-us/windows/client-management/mdm/policy-csp-defender#defender-attacksurfacereductiononlyexclusions) configuration service provider (CSP) to add exclusions.
## Customize the notification
See the [Windows Defender Security Center](../windows-defender-security-center/windows-defender-security-center#customize-notifications-from-the-windows-defender-security-center) topic for more information about customizing the notification when a rule is triggered and blocks an app or file.

3. In the **Group Policy Management Editor** go to **Computer configuration**.
4. Click **Policies** then **Administrative templates**.
5. Expand the tree to **Windows components > Windows Defender Antivirus > Windows Defender Exploit Guard > Controlled Folder Access**.
6. Double-click the **Configure controlled folder access** setting and set the option to **Enabled**. In the options section you must specify one of the following:
- **Enable** - Malicious and suspicious apps will not be allowed to make changes to files in protected folders. A notification will be provided in the Windows event log
- **Disable (Default)** - The Controlled Folder Access feature will not work. All apps can make changes to files in protected folders.
- **Audit Mode** - If a malicious or suspicious app attempts to make a change to a file in a protected folder, the change will be allowed but will be recorded in the Windows event log. This allows you to assess the impact of this feature on your organization.
![](images/cfa-gp-enable.png)
>[!IMPORTANT]
>To fully enable the Controlled Folder Access feature, you must set the Group Policy option to **Enabled** and also select **Enable** in the options drop-down menu.
### Use PowerShell to enable Controlled Folder Access
1. Type **powershell** in the Start menu, right click **Windows PowerShell** and click **Run as administrator**

## Review event logs for Exploit Protection
How do you see these event logs? Are they under specific codes/areas?
Also - is there any SCCM, Intune, or MDM functionality here? Can't see anything in the SCCM console.
## Review Exploit Protection events in Windows Event Viewer
You can review the Windows event log to see events there are created when Exploit Protection blocks (or audits) an app:
1. Download the [Exploit Guard Evaluation Package](#) and extract the file *ep-events.xml* to an easily accessible location on the machine.
2. Type **Event viewer** in the Start menu to open the Windows Event Viewer.
3. On the left panel, under **Actions**, click **Import custom view...**
4. Navigate to where you extracted *ep-events.xml* and select it. Alternatively, [download the XML directly](scripts/ep-events.xml).
4. Click **OK**.
5. This will create a custom view that filters to only show the following events related to Controlled Folder Access:

Network Protection is a feature that is part of [Windows Defender Exploit Guard](windows-defender-exploit-guard.md). It helps to prevent employees from using any application to access dangerous domains that may host phishing scams, exploits, and other malicious content on the Internet.
Network Protection helps to prevent employees from using any application to access dangerous domains that may host phishing scams, exploits, and other malicious content on the Internet.
It is part of [Windows Defender Exploit Guard](windows-defender-exploit-guard.md).
Network Protection works best with [Windows Defender Advanced Threat Protection](../windows-defender-atp/windows-defender-advanced-threat-protection) - which gives you detailed reporting into Windows Defender EG events and blocks as part of the usual [alert investigation scenarios](../windows-defender-atp/investigate-alerts-windows-defender-advanced-threat-protection).
You can enable Network Protection in either block or auditing mode (non-blocking, Windows Defender Advanced Threat Protection events only) with Group Policy, PowerShell, or MDM settings with CSP.
You can also use [audit mode](audit-windows-defender-exploit-guard.md) to evaluate how Network Protection would impact your organization if it were enabled.
