Other Cool Halo/API Tricks
• Set password reset requirements for a server user account.
• Find server accounts that don't have passwords (it happens)
• Find those spooky root-owned setuid files.
• Generate alerts if PID files go missing.
• Generate an alert if someone is in a group they shouldn't be in (like wheel).
• Generate massively detailed reports of server configuration status for auditors (keep 'em
busy for weeks).
• Get a report of every server that a user *does not* have an account on.
• Get a report of every server that a user has an account on.
• Get alerted if a new cloud server gets created.
• Learn what process that TCP/IP port is bound to.
• Make sure that init.d startup scripts can't be tampered with by non-root users.
• Make sure that services are not running with excessive privileges.
• Monitor servers to detect old user accounts that should have been cleaned up, but might
have gotten missed.
