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.

OR HOW TO RUN https://github.com/open-policy-agent/conftest AS CI/CD in Circle CI to apply policies?

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.

Running tcpdump on eks worker nodes
You can try using https://www.inspektor-gadget.io/ You can try either, top tcp, trace network-graph or trace tcp gadget. It's a CNCF sandbox project and it's kubernetes native so I think this should work.

Is there any OSS tool out there that would translate traffic flows into NetworkPolicies?
This works really well https://github.com/inspektor-gadget/inspektor-gadget/blob/main/docs/gadgets/advise/network-policy.md

What are some useful Kubernetes tools you can share?
I found this tool: https://github.com/kinvolk/inspektor-gadget great if you want to have a detailed debugging for running pods e.g all exec system calls or trace tcp connections etc.

How to Trace Linux System Calls in Production with Minimal Impact on Performance
The team behind traceloop has integrated it with the Inspektor Gadget project, so you can run traceloop on the K8s platform using kubectl. See the demos in Inspektor Gadget - How to use and, if you like, try it on your own.
