If a vulnerability does come along, then the monolithic container can become compromised. Some would say this is good for security, but this type of monolithic container is still subject to the increasing likelihood of new attack vectors against an aging codebase.

This makes it easy to install for the novice user, but there is no guarantee that the Docker environment is up to date.įurther compounding container deployment security is the fact that some containers do not have a complete root file system and administrators cannot log in at all. If you want a particular application, let’s say, a web server running Word Press, then you simply run a few short commands and your Word Press server is up and running. There is a trend of “turn-key” operating system deployments, especially in Docker. Traditionally this was a complete distribution installation, however, that has changed in a way that hinders security and increases the difficulty of systems administration. In practice, the operating systems running within these isolation technologies both operate from their own root file systems. In this case, branch prediction attacks equally affect containers and virtual machines so we can exclude that as a consideration for choosing containers or virtual machines. You might ask: But what about branch prediction attacks, like Spectre? It more difficult to escape a virtual machine environment than a container environment. The isolation is provided by hardware optimizations implemented in silicon by CPU manufacturers. Because the hardware is virtualized and running a separate kernel, virtual machines provide greater isolation than containers since they do not share the same kernel.

If a user has full control overĪ virtual machine, then they can install any operating system they wish. They boot their own kernel, have their own disks and attach network devices. Virtual machines are an emulated hardware environment provided by KVM. Linux namespaces allow the container to have its own process ID space, so `init` can be process ID 1, whereas, with chroot jails, the namespace was shared, so processes in the jail could not have a process ID of 1 since the host OS `init` process was already using process ID 1.Ĭontainers share the same kernel and they do not have direct access to hardware resources. ContainersĬontainers are similar to chroot jail in that all of the programs running within the container are executed in a way that they believe they have their own root file system. In today’s ecosystem, there are two predominant forms of workload isolation: containers and virtual machines. Isolation is important for security because if one workload is compromised, and they are not isolated, then others can be affected.
