Ensure all users' home directories exist

LowLevel 2Manual reviewcos

Description

Users can be defined in /etc/passwd without a home directory or with a home directory that does not actually exist. If the user's home directory does not exist or is unassigned, the user will be placed in "/" and will not be able to write any files or have local environment variables set.

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

Run the following script and verify no results are returned: #!/bin/bash grep -E -v '^(system-halt|sync|system-shutdown)' /etc/passwd | awk -F: '($7 != "'"$(which nologin)"'" && $7 != "/bin/false") { print $1 " " $6 }' | while read -r user dir; do if [ ! -d "$dir" ]; then echo "The home directory ($dir) of user $user does not exist." fi done

How it is fixed

Fix method: Guidance or infrastructure patch

If any users' home directories do not exist, create them and make sure the respective user owns the directory. Users without an assigned home directory should be removed or assigned a home directory as appropriate.
