Planning for unexpected cyberattacks
The need for cybersecurity has never been more critical in ensuring the resilience of any digital infrastructure, and to many governments it is considered an issue of national security in the realm of critical infrastructure protection. Tackling risks related to smart city safety, including cybersecurity, is paramount to ensuring the integrity and reliability of critical urban infrastructure. Cities can plan and be better prepared for unexpected cyberattacks through various strategies:
− Strong cybersecurity protocols: This includes encryption, firewalls, intrusion detection systems and regular security audits. For example, the city of Barcelona employs stringent cybersecurity protocols to safeguard its smart city infrastructure. − Education and training: Educate city employees and residents about cybersecurity best practices. Awareness campaigns and training programs can help individuals recognize and respond to potential threats. Singapore, for instance, conducts regular cybersecurity training sessions for city employees. − Incident response plans: Develop comprehensive incident response plans to mitigate the impact of cyberattacks. These plans should include strategies for data recovery, system redundancy and crisis communication. − Regular system updates: Keep all smart city systems and devices up to date with the latest security patches and updates. Vulnerabilities in outdated software are often exploited by cybercriminals. − Redundancy and resilience: Design smart city systems with redundancy and resilience in mind. This means having backup systems and fail-safes in place to ensure that critical services can continue to function even in the event of a cyberattack. Amsterdam, for example, prioritizes redundancy in its smart city infrastructure to prevent service disruptions. − Data encryption: Encrypt sensitive data to protect it from unauthorized access. Many smart city systems, such as those handling traffic data or surveillance footage, contain sensitive information that must be safeguarded. − Zero trust architecture: Implement a zero-trust architecture, which assumes that threats may exist both outside and inside the network. This approach enforces strict access controls and requires authentication for every user and device trying to connect to the network.
By implementing these strategies, as well as audits, collaboration with experts (public and private) and more, cities can significantly enhance their cybersecurity posture and better prepare for unexpected cyberattacks.

e-Estonia: Masterclass in e-services with e-governance
Estonia’s transformation journey to becoming one of the world’s most digitally advanced societies began with its pioneering commitment to implementing e-governance, which led to the establishment of e-Estonia. Over the past decade, e-Estonia has emerged as a global benchmark and role model for digital governance, setting the standard for other nations to follow.
Today, Estonia boasts a 99 percent availability of public services online. Virtually every aspect of life, from healthcare to agriculture to residency, involves an e-service. A key feature of Estonia's digital society is its mandatory electronic identity system. Every Estonian possesses a government-issued digital identity token, granting them authorized access to interact with the state and its services. Paired with digital signatures, citizens utilize this system to vote electronically, file taxes, and access medical records and banking services.
At the backbone of e-Estonia lies X-Road, a robust data management infrastructure designed to secure and unify data exchanges between public authorities, businesses and citizens. This open-source data exchange layer revolutionizes the traditional administrative structure, breaking down the silos that oftentimes disconnect entities and instead promotes seamless communication within the federated ecosystem. X-road enables parties to access and share data, effectively eliminating the costs and inefficiencies associated with redundant data storage and harvesting.
While Estonia places a strong emphasis on data security, the challenge of cybersecurity remains. The nation’s paperless government services and heavy reliance on information and communication technology make it a target for cybersecurity threats such as phishing, denial-of-service attacks, and the disruption of services. However, e-Estonia has demonstrated resilience and adaptability in preventing and addressing these challenges using cryptography and blockchain technology. These measures continue to transform the way public services are delivered, fostering efficiency, transparency and inclusivity in the digital era.
