Assessment Title

Rule Text

All OL 8 local interactive users must have a home directory assigned in the "/etc/passwd" file.

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.

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 [ ! -f "/etc/passwd" ]; then echo "PASS"; exit 0; fi
users=$(awk -F: '$3 >= 100 && $3 < 65534 && $NF != "" {print $1}' /etc/passwd); for user in $users; do home=$(cut -d: -f6 /etc/passwd | grep "^$user" | tr -d ':'); if [ -z "$home" ]; then echo "FAIL"; exit 1; fi; done; echo "PASS"; exit 0

Remediation

Assign home directories to all local interactive users on OL 8 that currently do not have a home directory assigned.
