Denmark is known for being one of the most digitized countries in the world. Most citizens communicate digitally with authorities and the healthcare system through applications such as e-box, borger.dk and so on.
In addition, Denmark is among the countries that have the highest number of smart devices per capita. All our devices – from watches and home security systems to speakers, coffee machines and indoor climate control – can be connected to the internet, so we can control everything from an app on our mobile phone. In 2018, every European owned an average of 5.6 smart devices that were connected to the internet. That number is expected to increase to 9.4 by 2023, according to German market and consumer database Statista.
And it is not only in our private sphere that we are digitized. Danish companies are well on board and offer apps and websites, just as many have moved production, email and digital office tools to the cloud. According to the Center for Cyber Security, 80 per cent of Danish companies that employ more than 100 employees make use of cloud computing, where the software solutions are located on the web rather than on the company's own servers and computers.
Each website, email, app, or smart device, provides a potential access point for IT criminals. They use these access points to enrich themselves through various forms of theft, fraud, and extortion.
The Center for Cyber Security assesses the threat from cyberespionage and cybercrime against Denmark as being very high.
When IT criminals manage to penetrate our systems it can prove to be a costly affair: American research firm Cybersecurity Ventures estimates that the total costs related to cybercrime in 2022 will amount to seven trillion US dollars worldwide.
The aim is there therefore to always be one step ahead of the IT criminals to avoid attacks.
At DTU, researchers contribute with solutions that can increase cyber security both today and in the future when the quantum computer becomes a reality.
