Comparison between security majors in virtual machine and linux containers

Virtualization started to gain traction in the domain of information technology in the early 2000’s when managing resource distribution was becoming an uphill task for developers. As a result, tools like VMWare, Hyper-V (hypervisor) started making inroads into the software repository on different operating systems. VMWare and Hyper-V could support multiple virtual machines running on them with each having their own isolated environment. Due to this isolation, the security aspects of virtual machines (VMs) did not differ much from that of physical machines (having a dedicated operating system on hardware). The advancement made in the domain of linux containers (LXC) has taken virtualization to an altogether different level where resource utilization by various applications has been further optimized. But the container security has assumed primary importance amongst the researchers today and this paper is inclined towards providing a brief overview about comparisons between security of container and VMs.
