 Attack surface reduction rules help prevent actions and apps that malware often uses to infect computers. You can set attack surface reduction rules for computers running Windows 10 or Windows Server 2019. 
 
-To use ASR rules, you need either a Windows 10 Enterprise E3 or E5 license. We recommend an E5 license so you can take advantage of the advanced monitoring and reporting capabilities available in Windows Defender Advanced Threat Protection (Windows Defender ATP). These advanced capabilities aren't available with an E3 license, but you can develop your own monitoring and reporting tools to use in conjuction with ASR rules.

 Attack surface reduction rules work best with [Windows Defender Advanced Threat Protection](../windows-defender-atp/windows-defender-advanced-threat-protection.md), which gives you detailed reporting into events and blocks as part of the usual [alert investigation scenarios](../windows-defender-atp/investigate-alerts-windows-defender-advanced-threat-protection.md).

+### Block credential stealing from the Windows local security authority subsystem (lsass.exe)
  
 Local Security Authority Subsystem Service (LSASS) authenticates users who log in to a Windows computer. Windows Defender Credential Guard in Windows 10 normally prevents attempts to extract credentials from LSASS. However, some organizations can't enable Credential Guard on all of their computers because of compatibility issues with custom smartcard drivers or other programs that load into the Local Security Authority (LSA). In these cases, attackers can use tools like Mimikatz to scrape cleartext passwords and NTLM hashes from LSASS. This rule helps mitigate that risk by locking down LSASS.
 
  >[!NOTE]
- >Some apps are coded to enumerate all running processes and to attempt opening them with exhaustive permissions. This results in the app accessing LSASS even when it's not necessary. ASR will deny the app's process open action and log the details to the security event log. Entry in the event log for access denial by itself is not an indication of the presence of a malicious threat.
