Picking your Deployment Architecture

In the previous post I talked about Smart Card Support in Red Hat Enterprise Linux. In this article I will drill down into how to select the right deployment architecture depending on your constraints, requirements and availability of the smart card related functionality in different versions of Red Hat Enterprise Linux.

To select the right architecture for a deployment where users would authenticate using smart cards when logging into Linux systems you need to

Discovery and Affinity

Questions related to DNS and service discovery regularly come up during deployments of Identity Management (IdM) in Red Hat Enterprise Linux in a trust configuration with Active Directory. This blog article will shed some light of this aspect of the integration.

We will start with a description of the environment. Let us say that the Active Directory  environment consist of

Migrating from third party Active Directory integration solutions

As predicted in one of my earlier posts, more and more customers are starting to seriously evaluate and move off of third party Active Directory integration solutions. They want to use or at least consider leveraging identity management technologies available in Red Hat Enterprise Linux.

In the calls and face to face meetings as well as during customer presentations at Red Hat Customer Convergence events, Red Hat Summit, Defence in Depth and other conferences I get a lot of questions about such migration. As it is becoming a common theme, I decided to consolidate some of the thoughts, ideas, and best practices on the matter in a single blog post.

Identity Management Improvements in Red Hat Enterprise Linux 7.3: Part 1

Red Hat Enterprise Linux (RHEL) 7.3 has been out for a bit, but have you looked at what we’ve added in the Identity Management area for this release? I’m excited to say, we’ve added quite a bit!

In the past I have been talking about individual features in Identity Management (IdM) and System Security Services Daemon (SSSD) but this is really not how we prioritize our efforts nowadays. We look at customer requests, community efforts, and market trends and then define themes for the release. So what were these themes for RHEL 7.3?

PCI Series: Requirement 1 – Install and Maintain a Firewall Configuration to Protect Cardholder Data

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

I Really Can’t Rename My Hosts!

Hello again! In this post I will be sharing some ideas about what you can do to solve a complex identity management challenge.

As the adoption of Identity Management (IdM) grows and especially in the case of heterogeneous environments where some systems are running Linux and user accounts are in the Active Directory (AD) – the question of renaming hosts becomes more and more relevant. Here is a set of requirements that we often hear from customers

Why Use SSSD Instead of a Direct LDAP Configuration for Applications?

In my Identity Management and Application Integration blog post I talk about how applications can make the most of the identity ecosystem. For example, a number of applications have integrated Apache modules and SSSD to provide a more flexible authentication experience.  Despite this progress – some (people) remain unconvinced. They wonder why they should use Apache modules and SSSD in conjunction with, for example, Active Directory instead of using a simple LDAP configuration… essentially asking: why bother?

Let’s look at this scenario in greater detail.  If an application supports

How Badlock Was Discovered and Fixed

Severity analysis of vulnerabilities by experts from the information security industry is rarely based on real code review. In the ‘Badlock’ case, most read our CVE descriptions and built up a score representing a risk this CVE poses to a user. There is nothing wrong with this approach if it is done correctly.  CVEs are analyzed in isolation; as if no other issue exists. In the case of a ‘Badlock‘ there were eight CVEs. The difference is the fact that one of them was in a foundational component used by most of the code affected by the remaining seven CVEs. That very specific CVE was
