Ensure user daemon is secured

MediumLevel 1Automatedaix

Description

This change locks and disables login access for the daemon user account. This change disables direct local and remote login to the daemon user account. Do not set a password on this account to ensure that the only access is via su from the root account. There should not be a requirement to log in as the daemon user directly. Audit: `lsuser -a account_locked login rlogin daemon` must show true/false/false; an absent account is compliant.

How it is checked

Audit method: Shell command

shell

command -v lsuser >/dev/null 2>&1 || exit 1; lsuser daemon >/dev/null 2>&1 || { echo compliant; exit 0; }; out=$(lsuser -a account_locked login rlogin daemon 2>/dev/null); [ "$out" = "daemon account_locked=true login=false rlogin=false" ] && echo compliant || echo "$out"

Expected output: compliant

How it is fixed

Fix method: Shell command

shell

chuser account_locked=true login=false rlogin=false daemon
