Remediation - Manual Procedure
Review the settings in /etc/auto.master and /etc/mapname for z/OS UNIX security parameters and configure the values to conform to the specifications below.
The /etc/auto.master HFS file (and the use of Automount) is optional.
The setuid parameter and the security parameter have a significant security impact. For this reason these parameters must be explicitly specified and not be allowed to default.
