Secure Information and Resource Sharing in Cloud

The significant threats from information security breaches in cyber world is one of the most serious security problems. Organizations are facing growing number of sophisticated cyber-attacks every year. Efficient and secure sharing of attack and security information during cyber incident response plays increasingly significant role in fixing the problems as well as helping organizations recover fast. While traditional systems are slow and inefficient in sharing information and resources securely, cloud platform provides us a considerable convenience to facilitate the sharing. In this paper, we propose access control models for secure information and resource sharing (IARS) in cloud Infrastructure as a Service (IaaS).
