Decommissioning: Your Building's Old Devices Are Someone Else's Problem

When building IoT devices reach end-of-life, what happens?
Often: Nothing. They get resold, donated, or recycled without secure data deletion or certificate revocation.
Result: A cheap "used smart building component" in a secondary market still contains:
Building occupancy patterns
Access control data
Historical sensor readings
Possibly authentication credentials
Known vulnerabilities nobody patched
That's a security liability waiting to compromise another building.
SBCGA-DECOM addresses this:
✓ Secure data destruction on retired devices
✓ Certificate revocation procedures
✓ Firmware documentation and deactivation
✓ Recycling chain tracking
✓ Documentation that device is unsupported
Your building's security lifecycle doesn't end when you stop using a device. It ends when the device is completely decommissioned—safely, securely, and documented.
End-of-life device management is just as important as procurement.
Make decommissioning systematic. Your building's future security depends on not leaving vulnerabilities in the secondary market.
