NCSC Sets Out Security Principles for Smart Cities Titled Connected Places Cyber Security Principles, the guidance aims to help local authorities in the UK embrace the benefits of connected places, while at the same time ensure they are resilient to cyber-attacks. The smart city concept involves the use of connected technology, such as IoT devices, to collect data and enhance services within a built environment. Examples of smart city technologies include the use of parking sensors to provide real-time data on space availability and sensors to monitor pollution levels. Despite these benefits, security experts believe smart cities will be heavily targeted by cyber-criminals via methods such as ransomware as a result of the critical public functions they will perform and the numerous security vulnerabilities that are associated with IoT devices.
