The CA API Gateway must be configured to prohibit or restrict the use of functions, ports, protocols, and/or services as defined in the PPSM CAL and vulnerability assessments.

Description
In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable or restrict unused or unnecessary physical and logical ports/protocols on information systems. ALGs 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. DoD continually assesses the ports, protocols, and services that can be used for network communications. Some ports, protocols, or services have known exploits or security weaknesses. Network traffic using these ports, protocols, and services must be prohibited or restricted in accordance with DoD policy. The ALG is a key network element for preventing these non-compliant ports, protocols, and services from causing harm to DoD information systems. The CA API Gateway must be configured to prevent or restrict the use of prohibited ports, protocols, and services throughout the network by filtering the network traffic and disallowing or redirecting traffic as necessary. Default and updated policy filters from the vendors will disallow older version of protocols and applications and will address most known non-secure ports, protocols, and/or services. However, sources for further policy filters are the IAVMs and the PPSM requirements.

Check Text ( C-71747r1_chk )
Open the CA API Gateway - Policy Manager. Select "Tasks" from the main menu and chose "Manage Listen Ports". Verify on the ports necessary to meet organizational requirements are listed. If there are ports in violation of organizational requirements, this is a finding.

Fix Text (F-77657r1_fix)
Open the CA API Gateway - Policy Manager. Select “Tasks" from the main menu and chose "Manage Listen Ports". Select any port in violation and then press the "Remove" button to remove that port in accordance with organizational requirements.
