Updates, upgrades, and uptime

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. Finally, ways of highlighting problematic hosts (with old operating systems and software) and prioritizing them helps your efforts to upgrade and secure your machines.

CFEngine Build System version 3

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.

If you haven’t yet got a hold of the latest version of cfbs, you can update it with pip using the following command:

CFEngine Build System version 2

A while back we released version 2 of cfbs, and even though we release versions of this tool quite frequently, without announcing it on the blog, we thought this was a good opportunity to talk a bit about the tool, what’s new and our direction with it in the future. The reason why we called this the “2.0” release is that we are trying to follow semantic versioning, and there were some big new features in the release which could be considered breaking changes.

Secure your hosts with CFEngine Build modules

Last year, we launched functionality for users to add policy for reporting data, compliance reports, promise types, and other code as modules. With CFEngine Build, users can manage and update their own policy, the default policy and any additional modules separately. This makes it very easy to utilize policy or other modules written by the CFEngine team, or other community members. In this post we will take a look at using some modules to improve the security of our infrastructure.

Writing a cfbs module for your custom policy update

I re-stumbled across this mailing list post from Bryan Burke about some policy framework upgrade issues where he also asked about hooking in and customizing the update policy. I thought this sounded like a good opportunity for an example using a cfbs module. So, let’s take a look at making a cfbs module for a custom update policy.
