BlackMatter actors use a separate encryption binary for Linux-based machines and routinely encrypt ESXI virtual machines. Go a step further by regularly updating your passwords and enabling multi-factor authentication (MFA). BlackMatter then remotely encrypts the hosts and shared drives as they are found,” reads the statement.

You can set up and package everything that you need into an application, and execute that package without the virtual machine overhead that is normally rendered during that process. A pod is a group of containers that are put together as a group on the same node (virtual machine) and are designed specifically for easy communication.

In this post, I’ll show you how to use Docker Machine with KVM and Libvirt on a Linux host (I’m using Fedora 27 as an example). Note that if your user account isn’t a member of the “libvirt” group, you’ll get prompted for authentication for most every docker-machine command, even just listing machines.).

Kubernetes nodes rely on underlying virtual servers for both the master control plane and for worker nodes. It is important to use security tooling such as OpenSCAP, the open source version of the Security Content Automation Protocol, to harden virtual machine images prior to their deployment in virtual private clouds.
