This publication responds to the need for providing fresh insights into the new international order, the Russian Federation's aggressive war against Ukraine, the protection of people and borders, armaments, and finally, the threats caused by digitalisation, artificial intelligence and cyberspace. It is also a reflection of the achievements made in the field of security studies by the Faculty of Political Science and International Studies, University of Warsaw – Poland's leading academic centre. Three departments in the Faculty actively pursue this area of research: the Department of Internal Security, the Department of Strategic Studies and International Security and the Department of Information Technologies.
