Assessment Title

Rule Text

The Red Hat Enterprise Linux operating system must be configured so that all local interactive user accounts, upon creation, are assigned a home directory.

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 the system are assigned a home directory upon creation.

Check to see if the system is configured to create home directories for local interactive users 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\\s*$" /etc/login.defs; then echo "PASS"; exit 0; else echo "FAIL"; exit 1; fi

Remediation

Configure the operating system 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
