A simpler alternative to Krane is rbac-tool, which can be installed as kubectl plugin. It can also analyze, audit, interrogate RBAC rules, but most importantly, it can visualize them:

Tool to create and visualize RBAC in cluster: https://github.com/alcideio/rbac-tool

Other tools that can also audit your existing RBAC permissions and Kubernetes setups are rbac-tool and rbac-audit.

And of course a quick google search shows that someone has already created something like that for RBAC: https://github.com/alcideio/rbac-tool

Role-Based Access Control (RBAC) should be configured for the Kubernetes cluster. Rights need to be assigned within the project namespace based on least privilege and separation of duties (RBAC-tool)

I've been tasked with defining and documenting some ClusterRoles with clear permissions that should (mostly) be enough for any kind of cluster. The idea is for admins (who don't necessarily do the devops behind) to be able to understand what each CR does, to assign these CRs to users on the fly, to update a user's access as their needs change, to view a list of policy rules, who can do what etc... For this maintenance and tracking part we use rbac-manager and rbac-tool, which are excellent tools imo.

I've just started using rbac-manager and rbac-tool to apply and track rbac on our clusters :)

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.

This works really well https://github.com/inspektor-gadget/inspektor-gadget/blob/main/docs/gadgets/advise/network-policy.md

Inspector gadget is a tool designed to introspect and debug Kubernetes applications using eBPF.

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.

All namespaces should have NetworkPolicy. Interactions between namespaces should be limited to NetworkPolicy following least privileges principles (Inspektor Gadget)

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.
