Security of new generation computing systems
Modern computing systems have become more easy-to-use, sophisticated and powerful, and have dramatically changed the way we live. However, the same systems add complexity and also introduce new interdependencies, vulnerabilities and privacy issues. There will be more ways to disrupt our life through cyber attacks. It is thus of great importance to consider and develop methods to mitigate those security risks. This special issue presents the recent advances on the security of new generation computing systems including distributed, cloud, and grid systems. We are pleased to present to you nine technical papers dealing with cutting-edge research and technology related to this topic. These papers were selected out of the significantly extended versions of the 173 submissions from 28 countries in the 6th International Conference on Network and System Security (NSS 2012) and a large number of open submissions. The selection has been very rigorous, and only the best papers were selected.
