About Us

Mission & People

The HGI, Research Department of the Ruhr-Universität Bochum (RUB), is one of the largest and oldest institutes in the field of IT security in Europe. The institute was founded in 2002 at RUB to address the Europe-wide deficits in public research on IT security.

Currently, around 160 scientists from computer science, electrical engineering, information technology and mathematics as well as the humanities and social sciences are conducting research at the Research Department IT Security.

Our research is driven by these goals and values:

Our Mission Statement

At HGI, we aim

  • to conduct pioneering and cutting-edge research and lay the foundations for future cyber security
  • to provide excellent teaching and job opportunities for young cyber security researchers
  • to protect the general public, developers and users of cyber security alike
  • to make results available to the general public and maximize societal benefit of research
  • to be an important mediator in communication and in creating awareness for cyber security
  • to be a leader in the transfer of knowledge and in creating startups
  • to be an orchestrator of IT security and business for Bochum.

What the HGI stands for:

  • We are unconventional, innovative, creative and interdisciplinary
  • We are fair and supportive in working together as a team
  • We are open-minded and invite a diverse, liberal and cosmopolitan corporate culture
  • We promote professional discussion and welcome open scientific discourse.

Working Group SicherDigi

SicherDigi (Security Production in the Digital Age) is an interdisciplinary research group that explores the topic of IT security from the perspective of the humanities and social sciences in close exchange with the technical sciences. SicherDigi investigates dynamics and processes of change at the intersection of the analog and the digital with a view to the question of how a need for IT security arises and what desired and unintended effects result from guaranteeing it. One focus is on empirical examples with a regional reference to the Ruhr region, which are used to concretize global developments. Both producers and consumers of IT security are taken into account. SicherDigi currently brings together RUB researchers from media science (Tuschling), philosophy (Weydner-Volkmann), law and criminology (Golla), social science (Sørensen, Galanova) and contemporary history (Goschler, Böick, Kirchberg).


SFB 1567

The Collaborative Research Center (SFB) 1567 "Virtual Lifeworlds" is an interdisciplinary network that researches the increase of virtuality in everyday life and the social and cultural transformation processes it sets in motion. It is dedicated to the virtual infusion of social subsystems and asks for consequences of individual subjects and their constitution, of lifeworld and aesthetic practices as well as social organizations and operations. The SFB gathers researchers from educational studies, German studies, history, art history, media studies and social sciences.

Rubin Special Edition IT Security

In June 2016, the first Rubin Special Edition IT Security was published. The science magazine of the Ruhr-University presents the multifaceted research interests of our scientists in a way that is easy to understand and thus provides exciting insights into the work at our institute. You can download the digital version of the complete magazine here (only in German).

The new special issue of Rubin on IT security was published in July 2023 - the issue can be found here as a download and flipbook.
