Smart cities are on the rise, promising improved efficiency, sustainability, and a better quality of life for residents. Copenhagen, for instance, wants to become the world’s first carbon-neutral capital by 2025, using IoT smart meters to monitor energy usage and promote sustainability.

However, to realize the vision of technologically enhanced smart cities, a solid foundation is crucial. Telecommunication companies and other infrastructure stakeholders play a vital role in establishing a framework for secure implementation of innovative technologies.

Previously, telcos operated within closed systems, but the shift to enterprise IT architecture requires collaboration with other vendors, which introduces security risks. Robust risk management strategies and security measures throughout the shared infrastructure are necessary.

Modern smart city architectures rely on cloud computing, edge computing, and virtualization and containerization technologies. While these technologies offer scalability and flexibility, they also introduce new security threats. Testing and hardening during the design phase, implementing robust security measures, and continuous audits are essential to ensure a secure and resilient ecosystem.

Securing supply chains and devices is another critical aspect. Dependence on components made in countries like China or Russia brings the concern of vulnerabilities. Careful supplier selection, component analysis, and collaboration with regulatory bodies help mitigate potential risks.

Purpose-driven design principles for IoT devices are paramount for security and efficiency. Devices should focus on specific use cases, reducing vulnerabilities. Lifecycle considerations are also important, as purpose-driven IoT devices simplify maintenance and updates, lowering operational expenses.

Building secure smart cities requires a balance between innovation and security. Advances in technology must go hand in hand with the safeguarding of residents’ privacy and safety. Incorporating security measures from the foundation and following industry best practices and standards are essential for successful smart city development.
