From Theory to Practice: Building a Smart Building Security Program

SBCGA is a framework. Academic and comprehensive.

But how do you actually implement it in a real building with real constraints?

Start small. Iterate. Expand.

Month 1: Device Inventory

• Know what you have

• Takes time but creates foundation

Month 2: Supportability Tracking

• When does each device's support end?

• Set calendar reminders for re-contracting

Month 3: Vulnerability Registry

• CVE subscriptions for your devices

• Monthly review meetings

Month 4: Cascade Assessment

• For your most critical devices, map what they connect to

• Understand your network dependencies

Quarter 2: Extended Support Contracts

• Begin re-contracting for devices losing support

• Get 7-10 year commitments in writing

Quarter 3: Supply Chain Review

• New procurements demand Bills of Materials

• Request firmware origin documentation

Quarter 4: Decommissioning Protocol

• Document your end-of-life process

• Secure data destruction procedures

Year 2+: Mature the program

• AI behavior monitoring

• Advanced supply chain verification

• Continuous governance evolution

This isn't a one-year project. It's a building governance program.

Start simple. Build systematically. Mature over time.
