Cyber Security

Computer and network security in a connected world

Irritating hacker attacks have in a few years evolved into targeted cyberattacks. Anna Nilsen

Secure IT systems are fundamental to modern society. Cybersecurity is a multifaceted and dynamic field of research, and one in which LiU has several leading research groups.

Digitalisation is revolutionising our society and bringing better efficiency, sustainability and a higher quality of life. This revolution has brought us to a position in which we are critically dependent on computer systems being available and in operation. What was previously just annoying hacker attacks have evolved into targeted cyberattacks threatening important systems that are crucial to safety. The increasing complexity and interdependence of software systems mean that attacks against even relatively minor systems can have huge consequences.

Linköping University conducts cutting edge research in the field of cybersecurity. The research has both theoretical and practical branches, and contributes to improving the safety and reliability of critical services, everything from cyber physical systems such as transportation and electricity distribution to cloud services and mobile devices.  

Examples of research topics are network security, web security, analysis of threats and risks, analysis of human behaviour, formal security analysis, integrity, computer forensics, adverse event detection and quantum cryptography.

LiU is leader of Resilient Information and Control Systems (RICS), a centre for research into the security of critical infrastructure.

A further important field of research is quantum cryptography, where LiU has its own laboratory.
