Description
All users must be assigned a home directory in the passwd file. Failure to have a home directory may result in the user being put in the root directory. This could create a Denial of Service because the user would not be able to perform useful tasks in this location.

ℹ️ Check
Verify each interactive user is assigned a home directory: # cut -d: -f1,6 /etc/passwd root srvproxy doejohn If an interactive user is not assigned a home directory, this is a finding. Verify that the interactive user home directories exist on the system: # cut -d: -f6 /etc/passwd \| xargs -n1 ls -ld drwxr-xr-x 2 doejohn staff 256 Jan 25 13:18 /home/doejohn drwxr-xr-x 2 sshd system 256 Aug 11 2017 /home/srvproxy drwx------ 2 root system 256 Jan 30 12:54 /root If any interactive user home directory does not exist, this is a finding.

✔️ Fix
Remove any unauthorized accounts with no home directory. If the account is valid, create the home directory using the appropriate system administration utility or process.
