Abstract
There has been a lot of recent excitement about cloud computing, with billions of dollars invested in infrastructure and companies flocking to outsource significant portions of their operations. Yet the security problems associated with storing and computing on data in the cloud are numerous and many remain unsolved. Cloud computing itself is a fairly new term, but is based on concepts that have been around for decades. Correspondingly, many issues involving cloud security are based on fundamental challenges of systems security. This talk will give an introduction to issues in cloud security and specifically about some of the current work in progress within the OSIRIS Laboratory on examining and confronting these issues. In particular, we will discuss novel investigations into the use of network flow watermarking to determine multi-tenancy on virtualized systems in the cloud and the potential threats to data confidentiality and integrity that may correspondingly result. We will also discuss methods of protecting data within the cloud through scalable and performant tracking of its provenance to ensure compliance and as a means of implementing finer-grained access control.
