“…The administrators of cloud computing are principally concerned with security and compliance (Modi, Patel, Borisaniya, Patel, & Rajarajan, 2013;Puthal et al, 2015). This introduces a number of cloud-related risks and threats (Khan, 2012;Zissis & Lekkas, 2012), thus leading to a shift in the roles of the staff ISACA, 2011;Pearson et al, 2012) in response to such concerns.…”

“…The inherent vulnerabilities of internal network in host and Local Area Network (LAN) pose threat to the VMs when they are live migrated. These security challenges are presented in (Modi et al 2012;Qina et al 2012;Ranjith et al 2012;. It is believed that the VM migration security is an important research area.…”

“…The network inside host and the LAN, in which migration is done, is vulnerable to attack just like physical network. This puts the VM guest OS and the applications hosted on it at risk (Modi et al, 2012;. The VM faces vulnerabilities when it migrates from one host to another (Clark et.…”

Context. Cloud Computing (CC) uses virtualization to provide computing resources on demand viaInternet. Small and large organizations benefit from CC because of reduced operating costs and increase in business agility. The migrating Virtual Machine (VM) is vulnerable from attacks such as fake migration initiations, service interruptions, manipulation of data or other network attacks. During live migration any security lax in VM firewall policy can put the VM data, OS and the applications on it at risk. A malicious VM can pose threat to other VMs in its host and consequently for VMs in LAN. Hardware firewalls only protect VM before and after migration. Plus, they are blind to virtual traffic. Hence, virtual firewalls (VFs) are used to secure VMs. Mostly; they are deployed at Virtual Machine Monitor-level (VMM) under Cloud provider"s control. Source VMM-level VF provides security to VM before the migration incurs and the destination VMM-level VF starts securing VM after migration is completed. It thus, becomes possible for attacker to use the intermediate migrating window to launch attacks on VM. Considering the potential of VFs there should be a great value in using open source VFs at VM-level for protecting VMs during migration, thereby, reducing the attacker"s slot to gain access to VM. It would enable hardened security for overall VM migration.Objectives. The aim is to investigate VM-level firewalling using open source firewall as a complementary security layer to VMM-level firewalling, to secure migrating VM in the CC domain. The first objective is to identify how virtual firewalls secure migrating VM in CC and to propose VMlevel open-source virtual firewalling for protecting VM during migration. Later the VF is implemented to validate and evaluate its intactness or activeness during migration in real Cloud data center.Methods. In the literary review 9 electronic libraries are used, which include IEEE Xplore, ACM Digital Library, SCOPUS, Engineering Village and Web of Knowledge. Studies are selected after querying libraries for 2 key terms "virtual machine" and "migration" (along with other variations/synonyms), in the abstract. Relevant papers on the subject are read and analyzed. Finally, the information gaps are identified. Using a lacuna the experimental solution is designed. To test the potential of VF at VM-level for migrating VM"s security the experimental validation is performed using stratification samples of firewall rules. The VF evaluation is done using continuous ICMP echo packet transmission. The packets are analyzed to determine firewall behavior during migration. To evaluate the validity, the VM migration is performed 8 times in City Network data center.Results. The literary review identified the widespread use of VMM-level firewalling for migrating VM"s security in CC. The VM-level VFs were not researched nor evaluated for intactness during migration. The experiment performed at City Network demonstrated that the VM-level VF secures VM during migration (on average) for 96% of migrati...
