Miguel Garcia

I am a PhD student at the Faculty of Sciences University of Lisbon and I am also a junior researcher at LaSIGE research group. My adivsors are Professor Alysson Bessani and Professor Nuno Neves. My mains research interests are Intrusion-tolerance, Diversity and Rejuvenations. I am also interested in topics such as Advanced Persistent Threats, DDoS attacks, Privacy concerns and Smart-grids security. In 2011 I have finished my M.Sc on Diversity Management in Intrusion Tolerant Systems, advised by Professor Alysson Bessani and Professor Nuno Neves. My thesis' contribution was a study on operating system vulnerabilities that showed that there is empirical evidence supporting the idea that the use of different operating systems on a replicated system makes the system more resilient. In 2008, while finishing my bachelor, I became a junior member of LaSIGE. I have contributed to FOREVER, advised by Professor Paulo Sousa and Professor Alysson Bessani. I have implemented a replicated system using virtualization (Xen Hypervisor) with different operating systems, and also a proactive recovery mechanism to replace the virtual machines with differente operating systems.
