For the holiday season gift yourself an improved infrastructure security posture.
Join Craig, Cody, and Nick as they wrap up 2022 and the 20th episode of The Agent is In reviewing CFEngines’ 2022 Holiday Security Calendar which has advice picked straight from industry standard security hardening guides like the OpenSCAP Security Policies and Security Technical Implementation Guides (STIGs). Craig demos new modules like maintainers-in-motd, file-permissions, enable-aslr, highlights guidance on writing your own security policies and more.
In the upcoming release of CFEngine 3.21.0 there is a change in behavior with respect to default permissions of created directories. From 3.21.0 and later directories will be created with read, write, execute permissions only for the file owner. No permissions are granted for group or other.
This change improves the default security posture to make sure that only the user executing cfengine (typically root) will have access to content in newly created directories.
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.
File promises, changes body To monitor a file for change in CFEngine you must have a files promise with a changes body attached.
The next LTS is coming …

cf-remote list Available releases: master, 3.20.0, 3.18.x, 3.
The good we secure for ourselves is precarious and uncertain until it is secured for all of us and incorporated into our common life. How often do you verify your compliance? Once or twice a year? Have you considered reporting on compliance continually?
The usual suspects, Cody Valle (Head of community), Criag Comstock (Digger), and Nick Anderson (Doer of Things) see how CFEngine Enterprise can be used to implement and report on compliance, specifically the Ubuntu 20.
Ever wish that you could run Mission Portal at Home?
Some of the CFEngine team gathers in Oslo Norway to do the show live, together. Criag Comstock (Digger) demonstrates how to use cf-remote to access new ARM64 packages for CFEngine Enterprise (Hub and Clients) and experiments with CFEngine Build in Mission Portal.

What’s autorun?
Autorun is a feature of the Masterfiles Policy Framework (MPF)1 that simplifies the process of adding and executing new policy.
We have talked about Modular policies with autorun and the Augments before. This time, we dig into autorun a bit deeper to explore some of its current features and look at how to implement your own as we did during The Agent is In, Episode 15 - Extending Autorun
