  • The DBN-6300 must provide the capability for organization-identified individuals or roles to change the auditing to be performed based on all selectable event criteria within near real time.

    <VulnDiscussion>If authorized individuals do not have the ability to modify auditing parameters in response to a changing threat environment,...

  • The DBN-6300 must compare internal information system clocks at least every 24 hours with an authoritative time server.

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

  • The DBN-6300 must record time stamps for audit records that can be mapped to Coordinated Universal Time (UTC).

    &lt;VulnDiscussion&gt;If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analys...

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.
