How to monitor specific Active Directory user groups, and set up a search to alert when members of these groups perform a login?

[arkonner]

I am looking to monitor specific AD user groups and want to create a search that alerts me to when the members of these group perform a login. How do I pull that information?

Sorry, my question was not clear - Active Directory user group perform login on Windows

Perform a login in Splunk or perform a login on a Windows machine?

If Splunk:

• Use the internal logs to monitor when a login success happens

  index=_internal sourcetype=splunk_web_service user=* action="login" status="success"

• Find if the user belongs to those groups via the ldap commands

If Windows:

• Collect Security event logs from required hosts
• Run a search in Splunk using the right Event Code for your Windows domain level. Also keep in mind logons can be interactive, remote, local, batch, etc so you need to use the Logon Type field too.
• Once you have the user, correlate with AD in the same way as above via the ldap commands in order to find out the user group membership
