Vendor Solution
Johnson Controls recommends the following mitigations: Host-based certificates using TLS 1.2: * Quickest solution * No Upgrade required to specific C•CURE or iSTAR software/firmware versions * Requires downloading a new certificate to all iSTAR panels simultaneously, resulting in a brief system downtime Convert encryption mode to TLS 1.3, per cluster: * Requires firmware 6.9.0 or higher, and C•CURE 9000 v2.90 SP3 or higher * Enables phased implementation by cluster, minimizing disruption * Note: TLS 1.3 is not supported on iSTAR eX, iSTAR Edge, and iSTAR Ultra LT panels Upgrade legacy panels to new G2 hardware: * Recommended for smaller systems due to time constraints * Applies primarily to iSTAR eX, iSTAR Edge, and iSTAR LT panels
