  • The Tanium operating system (TanOS) must, for networked systems, compare internal information system clocks at least every 24 hours with a server synchronized to one of the redundant United States Naval Observatory (USNO) time servers or a time server designated for the appropriate DOD network (NIPRNet/SIPRNet), and/or the Global Positioning System (GPS).

    &lt;VulnDiscussion&gt;Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the cor...

  • The Tanium Operating System (TanOS) must be configured to synchronize internal information system clocks with the primary and secondary time sources located in different geographic regions using redundant authoritative time sources.

    &lt;VulnDiscussion&gt;The loss of connectivity to a particular authoritative time source will result in the loss of time synchronization (free-run ...

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
