A Taxonomy of container security on computational clouds: concerns and solutions

VirtualizationincloudcomputinghasbeenusedincombinationwithenvironmentsPlatformas a Service (PaaS) and Infrastructure as a Service (IaaS) in order to provide performance, isolation, and scalability. However, containers and virtual machines (VMs) are susceptible to the vulnerabilities present in the core of operating system as well as container solutions, which are a risk for information and service operation of all entities sharing a same host. The safety recommendation guides aims to mitigate the security in this scenario, but the selection of containerization solutions taking into account security requirements is a complex task. Thus, we propose a security taxonomy focused on containers to cloud computing in order to assist the classification and evaluation containers security mechanisms and solutions.
