Enzoic for Active Directory

Logging and SIEM Integration


Log Files


Enzoic for Active Directory stores logs, by default, in
C:\ProgramData\Enzoic\Enzoic for Active Directory\Logs

The following log files are available:

LogType Filename(s) Format(s) Description
Console EnzoicConsole_{logDate}.json
EnzoicConsole_{logDate}.log
JSON
TXT
These are logs generated by the Enzoic console UI.
Service EnzoicService_{logDate}.json
EnzoicService_{logDate}.log
JSON
TXT
These are logs generated by the Enzoic service. These tend to be the most useful for troubleshooting and contain details for when a compromised password is found for a user by Compromised Password Protection as well as when a password change is blocked.
Filter EnzoicFilter.txt TXT These are logs generated by the Enzoic password filter DLL.

Logs rollover and are only stored for the last 7 days.

SIEM Integration


Enzoic for Active Directory logs important events to a JSON format log file which can be used for ingestion into SIEM systems. The following describes the information contained in these log entries.
