The integration of advanced technologies in smart buildings has indeed transformed the built environment, offering enhanced efficiency and adaptability. 

However, this digital evolution introduces significant cybersecurity risks that architects, engineers, and construction (AEC) professionals must address to ensure the safety and functionality of these structures.

The Broader Impact of Cybersecurity in Smart Buildings

Cybersecurity is not just an IT issue—it is a design and construction priority that impacts the long-term success of a project. 

Smart buildings rely on interconnected systems such as lighting, HVAC, security cameras, and access controls. While these innovations enhance functionality, they also expand potential entry points for cyberattacks. 

Research indicates that over half of these smart devices are susceptible to medium- or high-severity cyberattacks.

For architects, engineers, and contractors, addressing cybersecurity builds trust with clients, reduces liability, and ensures that smart buildings remain safe and functional in a rapidly evolving threat landscape.

The role of AEC professionals extends beyond delivering a physical structure; it includes designing the digital backbone that keeps these environments secure. 

By embedding cybersecurity into the workflow, AEC professionals can ensure their projects are not only smart but also resilient and future-ready.

Strategies for AEC Professionals to Enhance Cybersecurity

Cybersecurity in smart buildings starts long before the first brick is laid—it requires thoughtful planning, precise execution, and ongoing management. 

By incorporating the following strategies into their processes, AEC professionals can help mitigate cyber risks and deliver projects that stand resilient against evolving threats.

1. Design for Cybersecurity

Architects and engineers have a unique opportunity to build cybersecurity into their designs.

 Considerations include designing network segmentation to isolate critical systems, such as HVAC and access controls, from internet-facing networks. Specifying IoT devices that meet recognized security standards ensures they are less vulnerable to hacking. 

Planning for secure storage areas for servers and network equipment keeps them physically protected from unauthorized access. Early integration of cybersecurity measures reduces vulnerabilities that are costly to address later.

2. Ensure All Products Meet Cybersecurity Standards

AEC professionals often specify materials, devices, and systems during procurement. To enhance security, it is critical to vet all vendors and suppliers to ensure their products meet cybersecurity standards, like the following:

• ISA/IEC 62443: Select products certified under IEC 62443, which provides a comprehensive framework for securing industrial automation and control systems. 

• ISO/IEC 27001: While primarily focused on information security management systems, adherence to ISO/IEC 27001 indicates a commitment to robust cybersecurity practices.

3. Educating Building Owners and Facility Managers

As architects and engineers hand over projects, educating stakeholders about cybersecurity is critical. 

Developing user manuals with cybersecurity best practices tailored to the building’s systems ensures operators are prepared. Encouraging regular security audits identifies emerging vulnerabilities, while training operators to recognize and respond to cyber threats, such as phishing emails or abnormal system activity, enhances overall system security. 

Long-term security relies on informed management and regular system monitoring.

4. Recommending Advanced Monitoring Tools

When preparing Requests for Proposals (RFPs) or specifying technologies, AEC professionals can advocate for advanced monitoring solutions. 

Recommending intrusion detection systems that flag suspicious activity in real time, specifying software updates and patch management protocols as part of ongoing maintenance, and including requirements for remote diagnostics all support a more secure infrastructure. 

Proactive monitoring can mitigate threats before they cause significant damage.
