Monitor for attempts to use local accounts to log on remotely from other systems.  Event monitoring may be implemented through various methods including log aggregation and the use of monitoring tools.

Monitor for the events listed below.

More advanced filtering is necessary to obtain the pertinent information than just looking for event IDs.
Search for the event IDs listed with the following additional attributes:Logon Type = 3 (Network)
Authentication Package Name = NTLM
Not a domain logon and not the ANONYMOUS LOGON account

Successful User Account Login (Subcategory: Logon)
4624 - An account was successfully logged on.
Failed User Account Login (Subcategory: Logon)
4625 - An account failed to log on.

The "Pass the Hash Detection" section of NSA's "Spotting the Adversary with Windows Event Log Monitoring" provides a sample query for filtering.
