Machine learning in cybersecurity: Challenges and lessons learnt from research

The accelerated pace with which companies, governments and institutions digitalise parts of their functionality is creating opportunities for economic prosperity but at the same time increases the threat landscape. Cyberattacks are ever-increasing, with unintended consequences for the society. The rapid developments in the field of artificial intelligence, and machine learning in particular, may offer solutions in detecting, deterring and mitigating cyber threats. This talk will focus on two cases where machine learning can be applied, namely insider threat detection and spreading rumours on social media. It will cover challenges, lessons learnt from research projects and opportunities for further research.
