Vulnerability discussion

All ports, protocols, and services used on DoD networks must be approved and registered via the DoD PPSM process. This is to ensure that a risk assessment has been completed before a new port, protocol, or service is configured on a DoD network and has been approved by proper DoD authorities. Otherwise, the new port, protocol, or service could cause a vulnerability to the DoD network, which could be exploited by an adversary.SFR ID: FMT_SMF.1.1(2) b

Check content

Ask the MDM administrator for a list of ports, protocols, and services that have been configured on the host-based firewall of the BlackBerry UEM server or generate the list by inspecting the firewall. Verify all allowed ports, protocols, and services are included on the DoD PPSM CAL list. If any allowed ports, protocols, and services on the MDM host-based firewall are not included on the DoD PPSM CAL list, this is a finding.

Fix text

Turn off any ports, protocols, and services on the BlackBerry UEM host-based firewall that are not on the DoD PPSM CAL list.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
