Ensure herald is configured

LowLevel 1Automatedaix

Description

The contents of the herald are displayed to users prior to login for local terminals. Warning messages inform users who are attempting to login to the system of their legal status regarding the system and should include the name of the organization that owns the system and any monitoring policies that are in place. Audit: a default herald must be set in /etc/security/login.cfg (review wording against site policy).

How it is checked

Audit method: Shell command

shell

command -v lssec >/dev/null 2>&1 || exit 1; out=$(lssec -f /etc/security/login.cfg -s default -a herald 2>/dev/null) || exit 1; v=$(printf '%s\n' "$out" | sed -n 's/.*herald=\([^ ]*\).*/\1/p'); if [ -n "$v" ]; then echo compliant; else echo "herald=$v"; fi

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Add a default login herald to /etc/security/login.cfg with the appropriate contents according to your site policy: chsec -f /etc/security/login.cfg -s default -a herald="Authorized users only. All activity may be monitored and reported.\\nlogin: "
