TMA-AIX-4.1.2.11
Ensure root user has a dedicated home directory
Description
The root user must have a dedicated home directory and not use / as their home directory. By default, the home directory for the root user on AIX is /. This means that all configuration files and directories it creates are visible to all users and may be accessible if the root user has a weak umask setting. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
How it is checked
Audit method: Shell command
command -v lsuser >/dev/null 2>&1 || exit 1; out=$(lsuser -a home root 2>/dev/null) || exit 1; [ -n "$out" ] && [ "$out" != "root home=/" ] && echo compliant || echo "$out"- Expected output
compliant
How it is fixed
Fix method: Guidance or infrastructure patch
Create a new home directory for the root user mkdir /root Set ownership and permissions on this directory chown root:system /root chmod 0700 /root Update the home directory for the root user chuser home=/root root Move any necessary configuration files or directories to this new directory
