The Resilient Information Systems Security (RISS) Group is in the Department of Computing at Imperial College London. Broadly speaking, our work focuses on developing tools and techniques to enable systems to be resilient to malicious compromise and to continue to operate when they have been partially compromised. We tackle a broad variety of challenges in cybersecurity from malicious data injections in cyber-physical systems to adversarial machine learning in both centralised and federated settings, risk and resilience analysis with attack graph structures and work at the intersection of security and safety. Our work has attracted over £10M in funding from Industry, EPSRC and EU sources (see Current Projects and Past Projects for details) and led to numerous collaborations with both academic and industrial partners.
