[email protected] Academic Advisor: Prof. Tiago José dos Santos Martins da Cruz Date: July 01, 2014 Acknowledgements I would like to express my special appreciation and thanks to my advisor Professor Tiago Cruz for his excellent guidance, caring, patience, and providing me with an excellent atmosphere for doing research. I would also like to thank the LCT team and Professor Dr. Paulo Simões for all the support in my research. Finally, I would also like to thank my parents. They were always supporting me and encouraging me with their best wishes. Summary During the last years, some of the attacks towards SCADA made headlines, helping raise awareness . Some of the vulnerabilities may even be exploited to harm other systems, eventually, ending compromising specific points of SCADA networks. At the same time, a growing number of threats related with the physical layer made new issues and low-level mechanisms emerged, requiring careful approach and monitoring to secure such devices. Threats of this type are considered to be even more dangerous than SCADA-specific ones, since these operate at a lower level, unnoticed to scanners and anti-viruses. Considering this scenario we can expect a growing number of these threats to be affecting SCADA components, if adequate countermeasures are not taken. Over the last ten months (from September 16, 2013 until June 27, 2014), a new concept was developed, in the context of the FP7 CockpitCI project, for the current thesis, to reinforce the security of SCADA systems.
