Keys to the Kingdom, Smart Cities Security Concerns

Smart cities seem inevitable. According to IDC, Smart City initiatives attracted technology investments of more than £63 billion globally in 2018, and spending is estimated to grow to £122 billion in 2022. Similarly, in 2018, the number of major metropolitan cities relying on or developing a comprehensive smart city plan – as opposed to implementing a few innovative projects without an overall smart plan – dramatically increased.

A significant investment is being made by cities in data connectivity providing a number of w technologies such as Wi-Fi 6, smart grid, and IoT sensor devices, all promising to enhance overall visibility and security. However, as we extend the reach of technology and connectivity, there will increasingly be cyber-risks to take into account. As part of their transformation, smart cities serve as a technology hub and gateway to major institutions such as banks, hospitals, universities, law enforcement agencies, and utilities. This means the storage and transmission of customer data such as social security numbers, addresses, credit card information, and other sensitive data, is a potential goldmine for malicious actors. Not to mention an increasing number of projects monitoring roads, traffic, traffic light and metro services, all of which must be kept secure from threats at all times.

Moreover, the sheer volume of data being collected and transmitted across a multi-user network, with numerous locations, can be extremely challenging to protect. London’s City Hall Datastore, for example, holds over 700 sets of big data that helps address urban challenges and improve public services, and the rise in cashless payment methods for transport.

It is the complexity that the above factors represent that often overwhelms a network security team’s ability to ensure sensitive data is protected with encryption, especially when network infrastructures can be constructed using different vendor technology, many of whom do not provide strong encryption. This also includes many municipalities who have older Legacy, third party or disaggregated network.
It is therefore not a matter of if but when sensitive data may fall into the wrong hands. Network security teams have to ensure that any data breach must be detected immediately before the infection spreads from network system to network system, potentially shutting off critical services for thousands of companies, notwithstanding for those who reside in the City itself.
