Microfocus ArcSight Windows Native FlexConnector for Microsoft Sysmon tool https://technet.microsoft.com/en-gb/sysinternals/sysmon
Sysmon WINC Parser Updated for Sysinternals Sysmon v10.x - System activity monitor, Copyright (C) Mark Russinovich and Thomas Garnier
NOTE: when using DNS Query Logging functionality, you may want to ensure the ArcSight SmartConnector Java Image is whitelisted or does not carry out DNS lookups or you will see the original DNS Query as well as a followup query from the jre/bin/java.exe image on the SmartConnector Host.
Device / Product version: Sysmon v10.x, should be backward compatible to Sysmon v3. https://technet.microsoft.com/en-gb/sysinternals/sysmon
SmartConnector Type: Windows Native Connector Dependencies: Microfocus ArcSight SmartConnector Framework at least 7.4 (For automatic IPv6 Parsing)
Copy the fcp and acp folders and the contents to the CONNECTOR_HOME/current/user/agent/ folder on the Windows Native Connector
Add the following Event Log to the Windows Native Connector Custom Log section:Microsoft-Windows-Sysmon/Operational
or add directly to the agent.properties file:agents[0].windowshoststable[0].eventlogtypes=Microsoft-Windows-Sysmon/Operational
Restart the Windows Native Connector
