Distributed Log System in Cloud Digital Forensics

Abstract

Cloud computing is a promising future As number of VMs in the cloud increases the management problem becomes crucial; thus how to monitor enormous VMs is a critical study Due to the establishment of Personal Information Protection Act people stress more on the security–related topics Hence we can understand users’ usage conditions by analyzing the logs If it’s unusual it will be reported instantly to control the information security The key point of this thesis is to design a distributed system efficiently to use the network bandwidth to transmit a large number of logs and to reduce managers’ burdens for maintaining and managing VMs effectively with little extra costs Therefore according to the platform of cloud service this study highlights manager collecting enormous logs designs log transmission integrates logs to make progress on the log transmission of distribution management architecture and evaluate the system performance In the designed system logs are transmitted and collected efficiently this architecture not only saves the time to collect data that let the managers monitor the cloud environment in the meantime but also reduces load of log transmission for monitoring cloud services
