Evaluate attack surface reduction rules
Applies to:
Attack surface reduction rules help prevent actions and apps that are typically used by exploit-seeking malware to infect machines. Attack surface reduction rules are supported on Windows Server 2019 as well as Windows 10 clients.
This topic helps you evaluate attack surface reduction rules. It explains how to enable audit mode so you can test the feature directly in your organization.
Tip
You can also visit the Windows Defender Testground website at demo.wd.microsoft.com to confirm the feature is working and see how it works.
Use audit mode to measure impact
You can enable attack surface reduction rules in audit mode. This lets you see a record of what apps would have been blocked if you had enabled attack surface reduction rules.
You might want to do this when testing how the feature will work in your organization, to ensure it doesn't affect your line-of-business apps, and to get an idea of how often the rules will fire during normal use.
To enable audit mode, use the following PowerShell cmdlet:
Set-MpPreference -AttackSurfaceReductionRules_Actions AuditMode
This enables all attack surface reduction rules in audit mode.
Tip
If you want to fully audit how attack surface reduction rules will work in your organization, you'll need to use a management tool to deploy this setting to machines in your network(s). You can also use Group Policy, Intune, or MDM CSPs to configure and deploy the setting, as described in the main Attack surface reduction rules topic.
Customize attack surface reduction rules
During your evaluation, you may wish to configure each rule individualy or exclude certain files and processes from being evaluated by the feature.
See the Customize attack surface reduction rules topic for information on configuring the feature with management tools, including Group Policy and MDM CSP policies.
