 Attack surface reduction rules help prevent behaviors malware often uses to infect computers with malicious code. You can set attack surface reduction rules for computers running Windows 10, version 1709 or later, Windows Server 2016 1803 or later, or Windows Server 2019. 
 
 To use attack surface reduction rules, you need a Windows 10 Enterprise E3 license or higher. A Windows E5 license gives you the advanced management capabilities to power them. These include monitoring, analytics, and workflows available in [Windows Defender Advanced Threat Protection](../windows-defender-atp/windows-defender-advanced-threat-protection.md), as well as reporting and configuration capabilities in the M365 Security Center. These advanced capabilities aren't available with an E3 license, but you can use attack surface reduction rule events in Event Viewer to help facilitate deployment.
