The Silent Firewall: When Your Building's Network Security Blocks Its Own Lifeline
In modern commercial buildings, the same network security tools designed to protect you can inadvertently become the cause of a major operational outage. A routine firewall policy change, an expired certificate, or an overzealous intrusion prevention rule can block communication between your building automation system, access control panels, and the central management platform—without triggering any obvious alarms. By the time someone notices, tenants are without heat, doors won't unlock, or life-safety systems are offline. This episode explores the hidden tension between IT security and building operations, why these failures often surface only during critical events, and how facilities and IT teams can collaborate to prevent them. We discuss practical strategies for change management, exception handling, and communication that keep both security and uptime intact. Featuring insights from property management and facilities engineering perspectives, this is a must-listen for anyone responsible for the resilience of modern buildings.
