Smart Building Security Math That Doesn't Add Up

Here's the problem nobody talks about:
Your HVAC system will run for 15-20 years. The sensor controlling it? The manufacturer supports it for 5 years max.
By year 10, your "smart" building is running on firmware nobody's patching, controlling systems nobody's updated, with vulnerabilities nobody's tracking.
The EU Cyber Resilience Act mandates "lifetime" security support. But manufacturers can't commit to 15-year support and stay in business.
So we have an impossible regulatory requirement, inflexible infrastructure timelines, and buildings getting more connected every day.
Something has to give.
It's called SBCGA. Smart Building Cybersecurity Governance Architecture. A framework that actually works in the real world.
Not by demanding the impossible. But by distributing responsibility, managing vulnerabilities systematically, and acknowledging that device lifecycles matter.
This fifteen-year patch problem is real. But it's solvable.
Read the AC-146 paper. Learn SBCGA. Your building's security depends on it.
