A new CVE, (CVE-2016-9962), for the docker container runtime and runc were recently released. Fixed packages are being prepared and shipped for RHEL as well as Fedora and CentOS. This CVE reports that if you
execd into a running container, the processes inside of the container could attack the process that just entered the container.
If this process had open file descriptors, the processes inside of the container could
ptrace the new process and gain access to those file descriptors and read/write them, even potentially get access to the host network, or execute commands on the host.

It’s time to upgrade or to renew your VMware vSphere licenses. This decision is not easy for a few reasons such as:
You might be hesitantly considering paying for an upgrade and ELA renewal because you believe there is no (other) choice.
I have good news for you. There is a reliable and enterprise choice and switching has never been easier with the recent release of

We are continuing our series on how Red Hat Keeps the Lights on with Red Hat Virtualization. Please read our previous blog post if you missed any of the series. In this blog post, I will highlight how Red Hat IT uses JBoss Fuse and JBoss A-MQ to integrate our internal systems that support Accounting, Consulting, Engineering, Finance, Legal, Marketing, Operations, Sales and Training departments. Our internal Enterprise Service Bus (ESB) flows over 100,000 messages a day between these systems with wildly differing interchange and data formats. Our entire ESB deployment runs on virtual machines backed by Red Hat Virtualization. This deployment enables us to scale on demand to meet the changing needs of our business needs and integrated systems.

In my previous article I wrote about how it was possible to move from checkpoint/restore to container migration with CRIU. This time I want to write about how to actually migrate a running container from one system to another. In this article I will migrate a runC based container using runC’s built-in CRIU support to checkpoint and restore a container on different hosts.
I have two virtual machines (rhel01 and rhel02) which are hosting my container. My container is running Red Hat Enterprise Linux 7 and is located on a shared NFS, which both of my virtual machines have mounted. In addition, I am telling runC to mount the container

This post continues my series dedicated to the use of Identity Management (IdM) and related technologies to address the Payment Card Industry Data Security Standard (PCI DSS). This specific post is related to requirement eight (i.e. the requirement to identify and authenticate access to system components). The outline and mapping of individual articles to requirements can be found in the overarching post that started the series.
Requirement eight is directly related to IdM. IdM can be used to address most of the requirements in this section. IdM stores user accounts, provides user account life-cycle management

A few weeks ago, I wrote a blog on removing capabilities from a container. But what if you want to add capabilities?
While I recommend that people remove capabilities, in certain situations users need to add capabilities in order to get their container to run.
One example is when you have a app that needs a single capability, like an Network Time Protocol (NTP) daemon container that resets the system time on a machine. So if you wanted to run a container for an ntp daemon, you would need to do a
--cap-add SYS_TIME. Sadly, many users don’t think this through, or understand what it means to add a capability.

This is my sixth post dedicated to the use of Identity Management (IdM) and related technologies to address the Payment Card Industry Data Security Standard (PCI DSS). This specific post is related to requirement seven (i.e. the requirement to restrict access to cardholder data by business need to know). The outline and mapping of individual articles to the requirements can be found in the overarching post that started the series.
Section 7 of the PCI DSS standard talks about access control and limiting the privileges of administrative accounts. IdM can play a big role in addressing these requirements. IdM provides several key features that are related to access control and privileged account management. The first one is
