Assessment Title

Rule Text

All RHEL 9 local interactive user accounts must be assigned a home directory upon creation.

Description

Discussion Text

If local interactive users are not assigned a valid home directory, there is no place for the storage and control of files they should own.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Checks

DISA STIG (Manual Reference)

Verify all local interactive users on RHEL 9 are assigned a home directory upon creation with the following command:

$ grep -i create_home /etc/login.defs

CREATE_HOME yes

If the value for "CREATE_HOME" parameter is not set to "yes", the line is missing, or the line is commented out, this is a finding.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

if grep -qE '^\s*CREATE_HOME\s+(yes|"yes")' /etc/login.defs; then echo "PASS"; exit 0; else echo "FAIL"; exit 1; fi

Remediation

Configure RHEL 9 to assign home directories to all new local interactive users by setting the "CREATE_HOME" parameter in "/etc/login.defs" to "yes" as follows.

CREATE_HOME yes
