+description: This search looks for Event Code 4742 (Computer Change) or EventCode 4624 (An account was successfully logged on) with an anonymous account.
+how_to_implement: This search requires audit computer account management to be enabled on the system in order to generate Event ID 4742.
+  We strongly recommend that you specify your environment-specific configurations
+  (index, source, sourcetype, etc.) for Windows Event Logs. Replace the macro definition
+  with configurations for your Splunk environment. The search also uses a post-filter
+  macro designed to filter out known false positives.
