Distributed Computing and Internet Technology

The School of Computer Science at Tel Aviv University, Israel, has initiated and carried out a project titled “Teaching Computer Science in the Community”. The project aims to introduce scientific thinking and basic computer science concepts in an informal setting to school children from low socio-economic background. The project is implemented as a single semester undergraduate elective course, in which third year computer science students teach in schools and community centers. Here, we describe the spirit, content, and structure of the course and discuss insight we have gained over the last four years of teaching it. Attacks in the Resource-as-a-Service (RaaS) Cloud Context Danielle Movsowitz, Orna Agmon Ben-Yehuda, and Assaf Schuster Technion—Haifa Institute of Technology, Haifa, Israel dani.movso@campus.technion.ac.il, {ladypine, assaf}@cs.technion.ac.il, http://www.cs.technion.ac.il Abstract. The Infrastructure-as-a-Service (IaaS) cloud is evolving towards the Resource-as-a-Service (RaaS) cloud: a cloud which requires economic decisions to be taken in real time by automatic agents. Does the economic angle introduce new vulnerabilities? Can old vulnerabilities be exploited on RaaS clouds from different angles? How should RaaS clouds be designed to protect them from attacks? In this survey we analyze relevant literature in view of RaaS cloud mechanisms and propose directions for the design of RaaS clouds.
