The concept to save (i.e. checkpoint / dump) the state of a process, at a certain point in time, so that it may later be used to restore / restart the process (to the exact same state) has existed for many years. One of the most prominent motivations to develop and support checkpoint/restore functionality was to provide improved fault tolerance. For example, checkpoint/restore allows for processes to be restored from previously created checkpoints if, for one reason or another, these processes had been aborted.
Over the years there have been several different implementations of checkpoint/restore for Linux. Existing implementations of checkpoint/restore differ in terms of “what level” (of the operating system) they are operating; the lowest level approaches focus on implementing checkpoint/restore directly in the kernel while other “higher level” approaches implement checkpoint/restore completely in user-space. While it would be difficult to unearth each and every approach / implementation – it is likely fair to

This post is the fifth installment in my PCI DSS series – a 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 six (i.e. the requirement to develop and maintain secure systems and applications). The outline and mapping of individual articles to requirements can be found in the overarching post that started the series.
Section six of the PCI DSS standard covers guidelines related to secure application development and testing. IdM and its ecosystem can help in multiple ways to address requirements in this part of the PCI-DSS standard. First of all, IdM includes a set of Apache modules for

What if I told you that you can have your Red Hat Enterprise Linux (RHEL) based Cloud infrastructure, with Red Hat Virtualization, OpenStack, OpenShift and CloudForms all setup before you have to stop for lunch?
Would you be surprised?
Could you do that today?
In most cases I am betting your answer would be not possible, not even on your best day. Not to worry, the solution is here and it’s called the QuickStart Cloud Installer (QCI).
Welcome to another post dedicated to the use of Identity Management (IdM) and related technologies in addressing the Payment Card Industry Data Security Standard (PCI DSS). This specific post is related to requirement three (i.e. the requirement to protect stored cardholder data). In case you’re new to the series – the outline and mapping of individual articles to the requirements can be found in the overarching post that started the series.
Section three of the PCI DSS standard talks about storing cardholder data in a secure way. One of the technologies that can be used for secure storage of cardholder data is
This article is third in a 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 covers the PCI DSS requirement related to not using vendor-supplied defaults for system passwords and other security parameters. The outline and mapping of individual articles to the requirements can be found in the overarching post that started the series.
The second section of the PCI-DSS standard applies to defaults – especially passwords and other security parameters. The standard calls for the reset of passwords (etc.) for any new system before placing it on the network. IdM can help here. Leveraging IdM for centralized accounts and policy information allows for a simple automated provisioning of new systems with

In our third and final installment (see: part one & part two), let’s take a look at some high-level use cases for Linux containers as well as finally (finally) defending what I like to call “pet” containers. From a general perspective, we see three repeated high-level use cases for containerizing applications:
The fully orchestrated, multi-container application as you would create in OpenShift via the Red Hat Container Development Kit;
Loosely orchestrated containers that don’t use advanced features like application templates and Kubernetes; and

This article is one of the blog posts dedicated to 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 one – install and maintain a firewall configuration to protect cardholder data. The outline and mapping of individual articles to the requirements can be found in the overarching post that started the series.
The first requirement of the PCI standard talks about the firewalls and networking. While Red Hat’s Identity Management solution is not directly related to setting up networks and firewall rules, there are several aspects of IdM that

The Payment Card Industry Data Security Standard (PCI DSS) is not new. It has existed for several years and provides security guidelines and best practices for the storage and processing of personal cardholder data. This article takes a look at PCI DSS 3.2 (published in April of 2016) and shows how Identity Management in Red Hat Enterprise Linux (IdM) and related technologies can help customers to address PCI DSS requirements to achieve and stay compliant with the standard. If you need a copy of the PCI DSS document it can be acquired from the document library at the following site: www.pcisecuritystandards.org
In October of 2015 Red Hat published a paper that gives an overview of the PCI DSS standard and shows how Red Hat Satellite and other parts of the Red Hat portfolio can help customers to address their PCI compliance challenges. In this post I would like to expand on this paper and drill down into more detail about
