Cloud Computing Network Security using NetFPGA Platform NetFPGA未來網路平台上之雲端封包檢測技術 Prof. Jiann-Liang Chen 台灣科技大學陳俊良教授 Wireless Networks and Evolutional Communications Laboratory Definition Concept Cloud Computing providing unlimited infrastructure to store and execute customer data and program Benefits of Cloud Computing Minimized Capital expenditure Location and Device independence Utilization and efficiency improvement Very high Scalability High Computing power Cloud Computing Cloud Computing SERVICES MONEY $ = Definition Concept Cloud Computing Cloud Computing SERVICES MONEY $ = Definition Concept Cloud Computing Cloud Computing Roughly said that customers entrusted their precious assets to cloud computing providers So, what is the providers responsibility here? ?! hackers, virus ? system failures network problem disasters, electric outages? Vulnerabilities Cloud Computing what actually is expected by customers? 74.6% Security… Security What is necessary to be concerned by provides about cloud computing security? As a public data center, the cloud is very sensitive to intrusion, virus, attacks and malicious application-layer data, so it requires total situational awareness of the threats to the network, infrastructure and information. Cloud Computing Security So What About Security in the Cloud? Is it different from “Regular Security” In Some ways is NO SQL injections Cross site scripting Natural disasters Physical security In Some ways is YES SLA Again this is about service Infrastructure related Cloud Computing Security Three fundamental objectives of computing and network security Confidentiality Integrity Availability Availability is likely the most related objective with the “service” Infrastructure Problem The aspects of Cloud availability is very vast Service Policy and Management Problem Intrusions and Attacks Problem Physical and external Problem Cloud Computing Security Example on Intrusions and Attacks problem: Amazon C
