Windows Remote Management
Windows Remote Management (WinRM) is the name of both a Windows service and a protocol that allows a user to interact with a remote system (e.g., run an executable, modify the Registry, modify services).  It may be called with the
winrm command or by any number of programs such as PowerShell.

|Threat Group-3390||Threat Group-3390 has used WinRM to enable remote execution. |
|Disable or Remove Feature or Program||Disable the WinRM service.|
|Network Segmentation||If the service is necessary, lock down critical enclaves with separate WinRM infrastructure and follow WinRM best practices on use of host firewalls to restrict WinRM access to allow communication only to/from specific devices. |
|Privileged Account Management||If the service is necessary, lock down critical enclaves with separate WinRM accounts and permissions.|
Monitor use of WinRM within an environment by tracking service execution. If it is not normally used or is disabled, then this may be an indicator of suspicious behavior. Monitor processes created and actions taken by the WinRM process or a WinRM invoked script to correlate it with other related events.
