Details
Check Text (C-216341r959010_chk)
The root role is required.
Determine if the default umask is configured properly.
# grep -i "^UMASK=" /etc/default/login
If "UMASK=077" is not displayed, this is a finding.
Check local initialization files:
# cut -d: -f1 /etc/passwd | xargs -n1 -iUSER sh -c "grep umask ~USER/.*"
If this command does not output a line indicating "umask 077" for each user, this is a finding.
Fix Text (F-17575r371112_fix)
The root role is required.
Edit local and global initialization files containing "umask" and change them to use 077.
# pfedit /etc/default/login
Insert the line
UMASK=077
# pfedit [user initialization file]
Insert the line
umask 077
