Palo Alto Networks NDM Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The Palo Alto Networks security platform must compare internal information system clocks at least every 24 hours with an authoritative time server.
Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when condu...Rule Low Severity -
The Palo Alto Networks security platform must synchronize internal information system clocks to the authoritative time source when the time difference is greater than one second.
Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when condu...Rule Low Severity -
The Palo Alto Networks security platform 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.
The loss of connectivity to a particular authoritative time source will result in the loss of time synchronization (free-run mode) and increasingly inaccurate time stamps on audit events and other ...Rule Medium Severity -
The Palo Alto Networks security platform must record time stamps for audit records that can be mapped to Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT).
If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. Time stamps generated by the application include date and time and ...Rule Medium Severity -
The Palo Alto Networks security platform must only allow the use of secure protocols that implement cryptographic mechanisms to protect the integrity of maintenance and diagnostic communications for nonlocal maintenance sessions.
This requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP. Note that HTTP OCSP is permitted to ...Rule Medium Severity

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.
