October/November/December 2022 I 41 SECURIT Y As smart building technologies evolve, there is a concern about cybersecurity. This requires having only the data points needed to achieve the desired outcome being exchanged between systems. Using methods, such as seg- mentation, least privilege, firewalls, demilitarized zones (DMZs), and authorization are followed to maintain network security. As for any security posture, strong authentication and access control should be the first step for protection. Security is not just an add-on, but rather it is an immune system for an organization. VERTICAL APPROACH OF DIGITAL BUILDING SOLUTIONS Vertical integration is an essential part of an effective digitalization strategy. Increasing the number of data points within an IoT-enabled building enhances the variety and volume of information that can be collected and communicated by leveraging the number of sensors and components. Over time, total cost of ownership (TCO) and ease of implementation have been growth drivers. A vertical approach permits end-to-end solutions toward specific problems present in buildings, such as cost optimizations and energy savings. FIGURE 4: IoT intelligent connected building. A data fabric is generated everywhere in the envi- ronment where an ecosystem of sensory components in the building becomes part of the base infrastructure. No matter how unified the whole may appear, the parts each component plays are discrete and necessary. Considering the flexibility of a digital building with a PoE infrastructure, the more connected a building's system becomes with greater variety, volume, and velocity of data generation, the higher the potential for intelligent decision-making. See Figure 4. An occupancy sensor can be added to reduce an environment's carbon dioxide levels.
