Fix Recommendation

Follow the procedures below for each site hosted on the IIS 10.0 web server:

Under "IIS" double-click on the "Logging" icon.

If necessary, in the "Logging" configuration box, redesignate a log path to a location able to house the logs.

Under "Log File Rollover", deselect the "Do not create new log files" setting.

Configure a schedule to rollover log files on a regular basis.

Check Contents

Follow the procedures below for each site hosted on the IIS 10.0 web server:

Access the IIS 10.0 web server IIS 10.0 Manager.

Under "IIS" double-click on the "Logging" icon.

In the "Logging" configuration box, determine the "Directory:" to which the "W3C" logging is being written.

Confirm with the System Administrator that the designated log path is of sufficient size to maintain the logging.

Under "Log File Rollover", verify "Do not create new log files" is not selected.

Verify a schedule is configured to rollover log files on a regular basis.

Consult with the System Administrator to determine if there is a documented process for moving the log files off of the IIS 10.0 web server to another logging device.

If the designated logging path device is not of sufficient space to maintain all log files and there is not a schedule to rollover files on a regular basis, this is a finding.
