Tracking Your CloudFlare DNS Configuration
By Alistair Pialek
Email is a mission critical application that is relied on to power business
communication and collaboration capabilities on a day-to-day basis. It is a
vital component of modern business and being able to send and receive email
is of paramount importance. If you were to make a list of applications to
track and control configuration changes of, email would be at the top of that
Underpinning web and email communication, a businesses DNS zone file ranks as
one of the most important configuration files you have probably never heard
of and should certainly be continuously monitored. Even stored in the cloud
through a service such as CloudFlare, changes to your DNS zone file can still
occur causing disruptions to mission critical applications such as email,
which is what today's scenario will explore.
Declarative vs. Imperative Models for Configuration Management: Which Is
As a group of concepts, DevOps has converged on several prominent themes
including continuous software delivery, automation, and configuration
management (CM). These integral pieces often form the pillars of an
organization’s DevOps efforts, even as other bigger pieces like overarching
best practices and guidelines are still being tried and tested. Being that
DevOps is a relatively new paradigm - movement - methodology - [insert your

Three Steps for Integrating Security into DevOps
The fate of CSO John in The Phoenix Project is a good parable for
illustrating the dynamic and often conflicted relationship between Security
and IT Operations. Security can either become a separate, obscure, and

Security John goes through a mental breakdown before finally understanding
how to adapt and survive, but it doesn't have to be that hard.

Chopping Up the Can: How to Get More Done
By Greg Pollock
Today, DevOps is the latest and greatest in making work efficient. Before
that, Agile called on us to rework our development process. If we keep going
back we eventually reach Frederick Winslow Taylor and the birth of scientific
Taylor famously (or infamously) measured the time needed for every action in
a production process. While degrading for workers, it was also effective.
Taylor was able to pay higher wages because he made workers more efficient.
IT workers can't be "Taylorized"-they need to make deci... (more)
Using GuardRail to Validate Windows SChannel Update
We've seen a landslide of vulnerabilities announced in the last few months,
fromShellShock to Poodle, and it looks like that trend will only continue.
The discovery of a critical vulnerability in Windows SChannel-and the even
worse problems introduced with a hasty patch-has added a heap of unplanned
work for Windows IT pros.
GuardRail provides a really easy way to validate that the update has been
successfully applied and the registry keys deleted. In addition to giving you
validation that patches have been applied now, our Scha... (more)
