Security and threat
Understanding terrorism, cybersecurity and crime
Polarisation in our society is on the rise. What makes people increasingly radical? How do we protect ourselves from extremist, terrorist or criminal threats, be they physical or in the cyber world? And what role do intelligence services play in this?

Understanding terrorism, cybersecurity and crime
Leiden researchers study security in our society from various perspectives. We try to understand why people radicalise with regard to both left- or right-wing extremism and religious fundamentalism. When does radical ideology turn into political violence or terrorism? And how is organised crime a threat to society? To find answers, we look not only at the Netherlands but beyond our national borders as well.
This leads to the question of how we protect our society from such threats, with measures or security, for example. And how can a country or government deal with a crisis or threat to public security? We also research the flipside of this. What are the effects of the police or security services being given far-reaching investigative powers? Do we gradually turn into a police state? Striking a balance between the security of our society as a whole and protecting our fundamental rights, the right to demonstrate or to privacy, for instance, is an important theme for our researchers.
An increasing part of our life is played out on the internet and more and more processes are becoming digital. This makes cybersecurity an increasingly important aspect of keeping ourselves, our businesses and our digital infrastructure secure: ransomware attacks, for example, but also espionage or even interference by foreign powers. Our researchers study today’s digital threats but also the legal framework needed to increase cybersecurity while ensuring our fundamental rights are not limited.
