IoT Cyber Security or Smart Cities

Smart cities rely on highly connected digital ecosystems, combining IoT devices, mobile applications and cloud platforms to deliver critical public services, directly impacting daily life, public safety and citizen trust.

IoT devices, public information displays, transportation systems and municipal mobile applications operate as a single digital ecosystem. Any cybersecurity incident, from service disruption to unauthorized public messaging, can rapidly escalate into public panic and reputational damage for municipalities.

Under the Cyber Resilience Act (CRA), IoT products used in smart city infrastructures must meet cybersecurity requirements as products with digital elements. In addition, when municipalities develop or operate their own mobile applications, they are directly responsible for ensuring these applications are CRA-compliant.

CyberWhiz supports municipalities with a holistic cybersecurity approach that protects smart city infrastructures end-to-end, from connected devices in the field to mobile applications and backend services.

Cybersecurity Challenges in Smart City Infrastructures

Municipal smart city ecosystems typically include:

• IoT devices used in public transportation systems
• Mobile applications for ticketing, access control and payments
• Smart turnstiles, validators and access gates
• Digital information displays at bus stops and metro stations
• Traffic information panels on roads and highways
• Digital advertising and public communication displays

These systems are:

• Highly visible to the public
• Widely distributed across the city
• Often connected through heterogeneous networks

A successful cyberattack - such as device takeover or unauthorized content injection - can cause public panic, service disruption and severe reputational damage for municipalities.
