Tired of hand crafting policy and arguing with people about spacing and alignment? Longing for regularity and easier scanning of your policy no matter who wrote it?
Cody, Craig and Nick wrap up the second year of The Agent is In with Miek Gieben, CFEngine Community user and author of cffmt, a formatted written in go for CFEngine policy files. Check out the discussion about opinionated formatting, possible future developments and other tooling to improve qualify of life as a CFEngineer.

We are writing to inform you about a security issue that was discovered in CFEngine 3.6.0 and later versions. Our development team found the vulnerabiliy relating to inadequate access control / unauthorized access to system files. MITRE assigned the CVE identifier CVE-2023-26560. We have no indications that this vulnerability has been used or known outside of the CFEngine development team.
Explanation The issue is that Mission Portal users can access certain files through scheduled reports, as these reports are run with elevated privileges, without additional checks to limit what can be queried.
Having a list of software that is allowed to be installed on a host is a strategy to prevent and fix security gaps and maintain compliance with operational guidelines. This zero-trust methodology ensures that only explicitly permitted applications are allowed to be present on a host unlike package block-listing which enumerates an explicit list of software that is not allowed to be present. In fact, with a software allow-list, you are essentially block-listing everything except the software you allow.
Can you trust the integrity of your base operating system runtime?
Jason Rogers and Dr. Wesley Peck of Invary join Cody, Craig and Nick to chat about their Runtime Integrity technology. They discuss the challenges of Trust, Information Technology Knowledge Management, and how Invary fits in the SecOps, Systems Automation, Security and Compliance landscape. Nick shares an example of an early integration between CFEngine and the Invary RISe agent1 with reporting in Mission Portal and talks about the different ways to approach integration.
Opening and reading files may cause your program to block indefinitely. In this blogpost we'll discuss how to work around this issue.
In February, our team attended both FOSDEM and CfgMgmtCamp (Configuration Management Camp) in Belgium. At CfgMgmtCamp we held several talks, and we'll upload some of the recordings.

Using CFEngine there are many ways to group and classify your hosts. In order to group their hosts, our users use a combination of JSON files, CFEngine policy language (with variables, classes, and class expressions), host specific data and host filters in Mission Portal. With these features you can choose which hosts to show in reports, and you can make decisions on what changes to make on which hosts. There is, however, no straight forward way for a Mission Portal user to save a selection of hosts (a filter) and then start doing things (reports, changes) with those hosts.
What’s the best way to collect information when troubleshooting something with CFEngine?
Cody and Nick chat with Craig about cf-support a new tool shipping in the latest (and future) versions of CFEngine.
