Cybersecurity Requirements Are Reaching Decades-Old Building Networks
Building automation networks were designed for decades assuming physical isolation, with no expectation anyone would ever attempt a remote network intrusion, and that assumption has aged badly as buildings connected these systems to the internet for remote monitoring access. Regulators and insurers are now imposing cybersecurity requirements on building networks previously exempt from meaningful scrutiny, forcing owners to segment, patch, and monitor infrastructure many facility teams do not fully understand technically. The commercial consequence is retrofit spending justified by risk rather than comfort or energy savings, a category that barely existed as a budget line a decade ago.
