07 Remediation
• Replace the iSTAR Pro, Edge and eX door controllers with a current generation iSTAR door controller (such as iSTAR Ultra G2) which supports authentication and prevents the ICU from making configuration changes. • Ensure your iSTAR Ultra and Ultra LT door controllers are running firmware 6.6.B or greater.
