Who does this work

7 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-223744r970703_chk)

Refer to the FTPD started task procedure. If the SYSTCPD and SYSFTPD DD statements specify the TCP/IP Data and FTP Data configuration files respectively, this is not a finding. If the ANONYMOUS keyword is not coded on the PARM parameter on the EXEC statement, this is not a finding. If the ANONYMOUS=logonid combination is not coded on the PARM parameter on the EXEC statement, this is not a finding. If the INACTIVE keyword is not coded on the PARM parameter on the EXEC statement, this is not a finding.

Fix Text (F-25405r868834_fix)

Review the FTP daemon's started task JCL. Ensure that the ANONYMOUS and INACTIVE startup parameters are not specified and configuration file names are specified on the appropriate DD statements. The FTP daemon program can accept parameters in the JCL procedure that is used to start the daemon. The ANONYMOUS and ANONYMOUS= keywords are designed to allow anonymous FTP connections. The INACTIVE keyword is designed to set the timeout value for inactive connections. Control of these options is recommended through the configuration file statements rather than the startup parameters. The systems programmer responsible for supporting ICS will ensure that the startup parameters for the FTP daemon does not include the ANONYMOUS, ANONYMOUS=, or INACTIVE keywords. During initialization the FTP daemon searches multiple locations for the TCPIP.DATA and FTP.DATA files according to fixed sequences. In the daemon's started task JCL, Data Definition (DD) statements will be used to specify the locations of the files. The SYSTCPD DD statement identifies the TCPIP.DATA file and the SYSFTPD DD statement identifies the FTP.DATA file. The systems programmer responsible for supporting ICS will ensure that the FTP daemon's started task JCL specifies the SYSTCPD and SYSFTPD DD statements for configuration files.
