File integrity monitoring is an important aspect in managing your infrastructure. Tripwire and AIDE are often cited as necessary tools by compliance frameworks1,2,3. Of course CFEngine can manage a file to make sure it contains desired content, but did you know that CFEngine also has the capability to simply monitor a file for change? In this blog post we take a look at CFEngines’ changes attribute for files promises.

As it was well received last year, we decided to do another security-focused holiday calendar this year. The concept was roughly the same, but instead of only adding security hardening modules, we’ve also added in some other security advice and blog posts to improve the variety. Now that we’re halfway through to 24 (or 25), let’s recap the first half of the calendar.

In CFEngine Enterprise we collect information from each system in the infrastructure as inventory. Some inventory is available by default, and more can be added using modules or writing policy. You can use inventory information to create a Compliance Report with checks that determine if the information complies with your security requirements. In this blog post, we will use some modules from CFEngine Build which provide inventory data, and build a Compliance Report on top of those.

All software of any significant size has bugs, vulnerabilities, and other weaknesses. This includes the operating system (OS), libraries, command line tools, services and graphical applications. Across your infrastructure, you should have an overview of what operating systems and software you have installed. Additionally, automated ways of upgrading the OS, as well as packages are desirable.

Our beloved cfbs CLI tool for working with CFEngine Build is rapidly evolving. At the time of writing, we are currently at version 3.2.1. Thus I would like to take this opportunity to talk a bit about the latest and greatest features; including support for users to manipulate input parameters in modules, as well as a couple of new build steps.

We are pleased to announce two new patch releases for CFEngine, version 3.15.7 and 3.18.3! These releases mainly contain bug fixes and dependency updates.

For halloween this year, we wanted to share some scary scenarios along with security recommendations to help avoid them. All the names, companies and characters are made up, but the events and experiences are based on things which could happen, or have happened in the real world.
