Minimizing Information Disclosure to Third Parties in Social Login Platforms.
MINESTRONE is a novel architecture that integrates static analysis, dynamic confinement, and code diversification techniques to enable the identification, mitigation and containment of a large class of software vulnerabilities.
MEERKATS is a novel architecture for cloud environments that elevates continuous system evolution, adaptation, and misdirection as first-rate design principles.
SysSec is funded by the European Commission.
The SysSec project aims at building a european network of excellence in managing threats and vulnerabilities in the future Internet.
WOMBAT was funded by the European Union under the Seventh Framework Program.
The WOMBAT project aimed at providing new means to understand the existing and emerging threats that are targeting the Internet economy and the net citizens. To reach this goal, it involved: (i) real time gathering of a diverse set of security related raw data, (ii) enrichment of this input by means of various analysis techniques, and (iii) root cause identification and understanding of the phenomena under scrutiny.
NoAH was funded by the European Union under the Sixth Framework Program.
The NoAH project focused on the gathering and analysing of information about the nature of Internet cyberattacks. It has produced an infrastructure to detect and provide early warning of such attacks, so that appropriate countermeasures may be taken to combat them.
