Title

The firewall protecting the BES12 server platform must be configured to restrict all network traffic to and from all addresses with the exception of ports, protocols, and IP address ranges required to support BES12 server and platform functions. (Cat II impact)

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 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

Review the implementation of the firewall protecting the BES12 server with the site system administrator. Verify the firewall is configured to restrict all network traffic to and from all addresses with the exception of ports, protocols, and IP address ranges required to support the BES12 server. If the firewall protecting the BES12 server is not configured to restrict all network traffic to and from all addresses with the exception of ports, protocols, and IP address ranges required to support the BES12 server, this is a finding. Note: Required ports, protocols, and IP address ranges for the BES12 server are found in the Supplemental document.

Fix Text

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