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.

Cloud Security and Resilience: DevSecOps Tools and Practices
2. Kubebench: https://github.com/aquasecurity/kube-bench Kubebench is an open-source tool that checks whether Kubernetes is deployed according to security best practices as defined in the CIS Kubernetes Benchmark.

Evaluating and securing your Kubernetes infrastructure with kube-bench
However, no matter how well our applications are secured, the security of our entire IT environment ultimately depends on the security of our infrastructure. Therefore, in the lab to follow, we will shift our focus away from Kubernetes workloads and instead explore how we can evaluate and improve upon the security of our Kubernetes clusters with kube-bench, the industry-leading Kubernetes benchmarking solution developed by Aqua.

Implement DevSecOps to Secure your CI/CD pipeline
kube-bench checks whether Kubernetes is deployed securely by running the checks documented in the CIS Kubernetes Benchmark. We can deploy kube-bench as a Job that runs daily and consume its report in CI/CD to pass or fail the pipeline based on the level of severity.

Securing Kubernetes Cluster using Kubescape and kube-bench
kube-bench can be executed as a simple command on the host, as a container on the host using Docker command, or as a job inside Kubernetes Cluster. In case it is run inside a container/pod, it will need access to the PID namespace of the host system. The methods to run kube-bench in AKS, EKS, GKE, On-prem cluster, Openshift and ACK (Alibaba Cloud Container Service For Kubernetes) are different but well documented.

Top 6 Kubernetes Security Tools
Kube-bench, written as a Go application, is deployable as a container. Ready-made job.yaml files make it easy to run Kube-bench inside a Kubernetes cluster or on a managed Kubernetes service, such as Azure Kubernetes Service (AKS), Amazon Elastic Kubernetes Service (EKS), Google Kubernetes Engine (GKE), or OpenShift. Here's a link to Kube-Bench on Github
