Review the container platform documentation and deployment configuration to determine which ports and protocols are enabled. Verify the ports and protocols being used are not prohibited by PPSM CAL in accordance to DoD Instruction 8551.01 Policy and are necessary for the operations and applications. If any of the ports or protocols is prohibited or not necessary for the operation, this is a finding.

Fix Text (F-35977r600707_fix)
Configure the container platform to disable any ports or protocols that are prohibited by the PPSM CAL and not necessary for the operation.
