Cyber Security of digital systems is one of the key challenges of a modern society that relies on networked information infrastructures for a wide range of social, economic and political activities.

Threats to the integrity and functionality of these systems are numerous, diverse and dynamic, as are the ways in which opponents, criminal or political, can compromise or exploit them.

The Cyber ​​Security Research Group considers the nature and character of these threats and formulates appropriate ways of thinking and acting on cyber security in the service of society. The group is a hub for studying a wide range of issues in cyber security and related areas, including cyber warfare, national and military cyber strategy, critical infrastructure protection, information security, information warfare, digital surveillance, cybercrime and cyber espionage.

We encourage innovation in theory, concepts and methods and apply them to contemporary cyber security issues, while encouraging discussion and engagement in academia, businesses, the media and the general public.
