Why Does a BMS Need Cybersecurity?

The Founder's Explanation (Teach Exactly This Way)

"People lock the front door but leave the back garden gate open, thinking it is only the garden. But the garden connects to the house. Today a BMS is on the network, sometimes reachable from the internet — that is the open garden gate. Through it, someone can walk into the whole building, even the company network. It must be locked like any other door."

Teaching the Concept

The Open Garden Gate People lock the front door but leave the garden gate open — it is only the garden, they think. But the garden connects to the house. A BMS on the network, reachable from outside, is that open gate — and through it someone can reach the whole building, even the corporate network. A networked BMS is a door, and every door needs a lock. Why It Matters ``` IP-CONNECTED controllers on the network, internet-adjacent ENTRY POINT a weak BMS can bridge to the corporate LAN UPTIME TARGET attackers know buildings run 24/7 ANSWER defense-in-depth: layered, contained, secured ``` The Shift in Mindset ``` OLD 'it is just building controls, ignore it' NEW 'it is a networked system; secure it in layers' field / edge / cloud, each contained ``` A BMS is no longer just building controls; it is a networked system on your doorstep — and it needs the same layered defence as anything else.
