A New Method of Containment: IBM Nabla Containers
In the previous post about Containers and Cloud Security, I noted that most of the tenants of a Cloud Service Provider (CSP) could safely not worry about the Horizontal Attack Profile (HAP) and leave the CSP to manage the risk. However, there is a small category of jobs (mostly in the financial and allied industries) where the damage done by a Horizontal Breach of the container cannot be adequately compensated by contractual remedies. For these cases, a team at IBM research has been looking at ways of reducing the HAP with a view to making containers more secure than hypervisors. For the impatient, the full open source release of the Nabla Containers technology is here and here, but for the more patient, let me explain what we did and why. We’ll have a follow on post about the measurement methodology for the HAP and how we proved better containment than even hypervisor solutions.
The essence of the quest is a sandbox that emulates the interface between the runtime and the kernel (usually dubbed the syscall interface) with as little code as possible and a very narrow interface into the kernel itself.

Kubernetes 1.12 Arrives With TLS and Better Cloud Integrations
The Kubernetes project has been hurtling at breakneck speed towards the boring. As the popular open source container orchestration platform has matured, it’s been the boring features which have come front and center, many of which focus on stability and reliability. For the Kubernetes 1.12 release on Thursday, those working on the project and on the various special interest groups (SIGs) initially laid out over 60 proposed features. A little over half of those made it to the final release, with many more being pushed back or delayed, as usual.
Amongst the changes that made it into this release are such additions as the general availability of TLS bootstrapping, the ability to use the Kubernetes API to restore a volume from a volume snapshot data source, a newly beta version of the KubeletPluginsWatcher, and some groundwork which is being put in place to solve scheduling challenges that confront large clusters

Platform9 Open Sources Its Kubernetes Etcd Support Tool
Platform9 pushed its etcdadm support tool out into the open source community via GitHub in an effort to generate momentum behind automating the configuration, deployment, and management of etcd clusters used by Kubernetes to store control plane information. Those tasks are currently either part of more broadly-focused efforts put on the shoulders of a Kubernetes user, or cobbled together by developers.
Etcd is the primary storage location for Kubernetes and needs to be established before Kubernetes can be run on a system. Arun Sriraman, Kubernetes technical lead manager at Platform9, explained in a video that etcd is the “backbone for Kubernetes storage.”

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
