Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Kubernetes Security Checklist 2021
Workload configuration should be audited regularly (Kics, Kubeaudit, Kubescape, Conftest, Kubesec, Checkov)

Don't let your Terraform go rogue with Conftest and the Open Policy Agent
Insert Conftest! As they state in their GitHub description, Conftest tests against structured configuration data using the Open Policy Agent Rego query language. In the case of Terraform, this means we're actually running unit tests against sample JSON and actual tests against the Terraform state JSON.

Using Open Policy Agent and Conftest to Validate Your Openshift 4 IPI Configuration
While Rego is the policy language we use to assemble our policies, we still need something to run those policies with. If you have a cluster and you want to actively evaluate policies, you can end up running an instance of Open Policy Agent and it's associated tooling. However in our case, we just want to check things at runtime (or just on some recurring basis such as when changes get checked in or a pull request is submitted). In the latter instance, we are able to use another tool from the Open Policy Agent project called ConfTest. What ConfTest allows us to do is to specify a file or directory of files that we want to inspect along with the set of policies we want to inspect them with. It then takes all of that and dumps out the associated outputs from those policies and tell us the results (i.e. the messages, how many policies were checked and the results of those policies). This tool is much better suited for our use case, so this is what we will proceed with. To grab the latest version of ConfTest, you can grab the latest release from here.

Terraforming in 2021 – new features, testing and compliance
If you like terraform-compliance, Conftest might also be worth having a look. It has its own DSL to write policies, and allows you to test multiple frameworks. We found this blog post from Lennard Eijsackers very informative, and would thus rather recommend you to check it out.

Mental models for understanding Kubernetes Pod Security Policy PSP
Can Gatekeeper and Conftest single-source the same set of rules? I'm looking at https://github.com/open-policy-agent/conftest/issues/54#issuecomment-528988831 and not seeing how.

An Overview of Kubernetes Security Projects at KubeCon Europe 2023
Falco is a well-known open source security solution originally created by Sysdig. It’s a CNCF incubating project and one of the few (as far as I can tell) options on this list that uses eBPF to scan for vulnerabilities.

My GoLab 2022 experience
On the cgo side I want to highlight two talks: one from Loris Cro about dealing with cross-complition difficulties, that the usage of cgo brings, using the Zig language and the other from Jason Dellaluce and Leonardo Grasso about how to extend Falco, a Kubernetes threat detection engine, which is written in C++, with plugins written in Go, explaining the challenges of integrating cgo in both C and Go.
