Service Installed Event Audit

Find All Windows Events for Installed Services

The Windows event log contains masses of valuable information. Using the event log scanning, you can find exactly when and which service was installed along with all the details of where it was installed, in what state and also by who. Scanning this on high-value assets is important to prevent unauthorized services that are not planned from being installed. You can read more about this use case in the Pro Tips #8 blog post.

To scan this event, configuration is required. Please follow the configuration steps in the Pro Tips #8 blog post.

This audit will provide you with a complete overview of all events with event ID 4697 that meet the following requirements:

  • All events where "Service File Name" is not located in %windir% or "Program Files/Program Files (x86)" folders. Typically new services are located in these folders.
  • All "Service Type" equals "0x1", "0x2" or "0x8". These service types start first and have almost unlimited access to the operating system from the beginning of the operating system startup. These types are very rarely installed.
  • All "Service Start Type" equals "0" or "1". These service start types are used by drivers, which have unlimited access to the operating system.
  • All "Service Start Type" equals "4". It is not common to install a new service in the Disabled state.
  • All "Service Account" not equals "localSystem", "localService" or "networkService" to identify services which are running under a user account.
