Fix Recommendation

Create home directories to all local interactive users that currently do not have a home directory assigned. Use the following commands to create the user home directory assigned in "/etc/ passwd":

Note: The example will be for the user smithj, who has a home directory of "/home/smithj", a UID of "smithj", and a Group Identifier (GID) of "users" assigned in "/etc/passwd".

# mkdir /home/smithj
# chown smithj /home/smithj
# chgrp users /home/smithj
# chmod 0750 /home/smithj

Check Contents

Verify local interactive users on the system have a home directory assigned and the directory exists.

Check the home directory assignment for all local interactive non-privileged users on the system with the following command:

# awk -F: '($3>=1000)&&($7 !~ /nologin/){print $1, $3, $6}' /etc/passwd

smithj 1001 /home/smithj

Note: This may miss interactive users that have been assigned a privileged UID. Evidence of interactive use may be obtained from a number of log files containing system logon information.

Check that all referenced home directories exist with the following command:

# pwck -r
user 'smithj': directory '/home/smithj' does not exist

If any home directories referenced in "/etc/passwd" are returned as not defined, or if any interactive users do not have a home directory assigned, this is a finding.
