Vulnerability discussion

Most information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizational operations. Since the MDM server is a critical component of the mobility architecture and must be configured to only those ports, protocols, and services (PPS) necessary to support functionality, all others must be expressly disabled or removed. A firewall installed on the MDM server provides a protection mechanism to ensure unwanted service requests do not reach the MDM server and outbound traffic is limited to only MDM server functionality.SFR ID: FMT_SMF.1.1(1) Refinement

Check content

Ask the MobileIron administrator for a list of ports, protocols and IP address ranges necessary to support MDM server and platform functionality (should also be listed in the STIG Supplemental Procedures document). Review the list to determine if the stated required configuration is appropriate: 22/tcp open ssh 80/tcp open http 443/tcp open https 8443/tcp open https-alt Compare the list against the configuration of the firewall, and identify discrepancies. If the network firewall protecting the MobileIron Core MDM appliance is not configured to support only those ports, protocols, and IP address ranges necessary for operation, then this is a finding.

Fix text

Configure the DoD-approved firewall to deny all except for ports listed in the STIG Supplemental document.
