Abstract

Cyber Security and Resource Scheduling are two critical aspects of cloud systems.  First, it is critical to defend cloud system against malicious attack due to their usage in military and critical commercial applications such as telehealth, battleship, router, aircraft, etc. A hostile penetration in such facilities could cause dramatic damage. It is known that buffer overflow attacks have been causing serious security problems. I proposed a hardware/software codesign method to solve the buffer overflow problem. Combining hardware/compiler, our approach provides different levels of strength to solve two types of attacks: For the most common stack smashing attacks, it provides a complete protection. For the function pointer attack, it makes a hacker extremely hard to change a function pointer leading to his hostile code. Second, for cloud computing,  it is necessary to implement a mechanism to allocate resource and schedule the execution order of tasks.  A resource optimization mechanism with preemptable task execution can increase the utilization of clouds. We propose two online dynamic resource allocation algorithms for the IaaS cloud system with preemptable tasks. Our algorithms adjust the resource allocation dynamically based on the updated of the actual task executions. In future, we will study the trade off between security level and performance in cloud systems.
