Sentry must be running an operating system release that is currently supported by MobileIron.

Network devices running an unsupported operating system lack current security fixes required to mitigate the risks associated with recent vulnerabilities.

Verify the Sentry is a supported version.

1. Enter the Sentry System Manager Portal URL in a web browser. 2. View the version number in the top right corner. 3. Check the MI Support page (help.mobileiron.com) to ensure the MI Sentry is a supported version.

If the version number of the Sentry appliance is not supported, this is a finding.

Install the most current MobileIron supported version of Sentry.
