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 MDM server is a critical component of the mobility architecture and must be configured to enable 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.

Check Content

Ask the MDM administrator for a list of ports, protocols, and IP address ranges necessary to support MDM server and platform functionality. A list can usually be found in the STIG Supplemental document or MDM product documentation.

Compare the list against the configuration of the firewall and identify discrepancies.

If the host-based firewall is not configured to support only those ports, protocols, and IP address ranges necessary for operation, this is a finding.

Fix Text

Configure the firewall on the MDM server to only permit ports, protocols, and IP address ranges necessary for operation.
