As lighting systems become more connected and integral to smart building IoT networks, they present new and attractive targets for cyber threats. A networked luminaire can serve as an entry point to a building’s broader data system. Consequently, data and network security has rapidly escalated from an afterthought to a fundamental design requirement. Leading manufacturers are now collaborating with cybersecurity firms to embed robust security protocols at the hardware and firmware levels. This includes secure boot processes, encrypted data transmission, regular over-the-air security patch updates, and rigorous vulnerability testing. Industry consortia are working to establish universal security standards for connected lighting devices to ensure interoperability and baseline protection. For specifiers and building owners, understanding a lighting provider’s security credentials—such as adherence to ISO 27001 or specific IoT security frameworks—is becoming as important as evaluating photometric data. Ensuring the integrity and safety of the lighting network is paramount to realizing the full benefits of smart, connected illumination without introducing systemic risk.
