No doubt connectivity scope increases exposure, making vigilant protections imperative. Aside from controller-level safeguards like event logging, using VLAN partitioning and firewall zoned DMZ perimeters for the intercom system limits blast radii if any units get compromised. Furthermore, automated firmware updates must ensure all connected units continually run the latest secure software revisions. Redundant monitoring servers check for tampering. Defense-in-depth approaches minimize attack vectors community-wide.
