A Literature Survey on Virtualization Security Threats in Cloud Computing

Brona Shah ^[2] | Jignesh Vania ^[3]

Abstract: Cloud Computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources, (for example networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. But it has many security issues they are Lack of trust, loss of control and multitenency. In cloud computing at IaaS Infrastructure is provided so Virtual machines are running in this level and service has been provided. SO there is one security threat is VM Migration. So for preventing this VM Migration problem one protocol is used so through that protocol this problem become less. At this level different VMs of different users are running on the same physical server. So another problem at this level is risk of co-resident attack, in which user of one VM can get information from the another VM. So for reducing this co-resident Attack different policies are there which perform the best when servers are properly configured but if not then there is a risk of co-resident attack so for reduce the risk of this new policy is there in which Previously selected server First is used that is for allocating the server for user. But still there is problem so that another policy in which one agent is there which checks the user and authenticate them and if there is any malicious VM then it discard it so that possibility of co-resident attack is becoming less and efficiency will be improve and secure services are being provided. So in this paper survey on virtual machine threats mainly VM Migration and Co-resident Attack is discussed.
