Securing Building Management Systems (BMS) in Financial Services

As financial services companies continue to adopt cutting-edge technology to streamline operations, enhance customer experiences, and optimize resources, their reliance on smart building systems grows in parallel. Building Management Systems (BMS), often referred to as Building Automation Systems (BAS), have become vital components for managing HVAC systems, lighting, physical security, and other building functions. These systems offer efficiency, cost savings, and greater control. However, as their connectivity to the internet and internal networks increases, so do their vulnerabilities, exposing financial services companies to a growing array of cyber threats. Securing BMS is no longer just an operational necessity—it is a matter of protecting critical infrastructure, data, and organizational reputation.

This white paper explores the challenges of securing BMS in financial services, highlights real-world examples of cyber threats, and offers actionable strategies to strengthen cyber defenses.
