Description
Configuration settings are the set of parameters that can be changed in hardware, software, or firmware components of the system that affect the security posture and/or functionality of the system. Security-related parameters are those parameters impacting the security state of the system, including the parameters required to satisfy other security control requirements.

ℹ️ Check
Ask the System administrator fora list(s) of the locations for all FTP Control cards within a given application/AIS, ensuring no FTP control cards are within in-stream JCL, JCL libraries or any open access data sets. If access to PDS files where FTP Control cards are stored are not restricted to appropriate personnel this is a finding.

✔️ Fix
Make sure that the FTP control Cards for each FTP are stored in a secure PDS and that they are not placed in the JCL libraries or in the in-stream JCL for each FTP.
