The IBM z/OS FTP server daemon must be defined with proper security parameters.

Description
The FTP Server daemon requires special privileges and access to sensitive resources to provide its system services. Failure to properly define and control the FTP Server daemon could lead to unauthorized access. This exposure may result in the compromise of the integrity and availability of the operating system environment, ACP, and customer data.

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-223742r958482_chk)

From z/OS command screen enter: ListUser FTPD OMVS (FTPD is usual name of the FTP daemon) If all of the following are true, this is not a finding. If either of the following is untrue, this is a finding. -The FTPD userid is defined as a PROTECTED userid. -The FTPD userid has the following z/OS UNIX attributes: UID(0), HOME directory '/', shell program /bin/sh. From z/OS command screen enter: RList STARTED FTPD If a matching entry in the STARTED resource class exists enabling the use of the standard userid and appropriate group, this is not a finding.

Fix Text (F-25403r868832_fix)

Define the FTP daemon userid and a matching entry in the STARTED resource class enabling the use of the standard userid and an appropriate group. Define the FTPD userid as a PROTECTED userid. Define the FTPD userid with the following z/OS UNIX attributes: UID(0), HOME directory '/', shell program /bin/sh. Sample commands to accomplish these requirements are shown here: Add the FTPD userid: AU FTPD NAME('STC, FTP Daemon') NOPASSWORD NOOIDCARD DFLTGRP(STCTCPX) OWNER(STCTCPX) OMVS(UID(0) HOME('/') PROGRAM('/bin/sh')) RDEF STARTED FTPD.** UACC(NONE) OWNER(ADMIN) AUDIT(ALL(READ)) STDATA(USER(=MEMBER) GROUP(STCTCPX) TRACE(YES)) Additional permissions may be required.
