A curated list for Kubernetes (K8s) Security resources such as articles, books, tools, talks and videos.
Disclaimer
Most of the resources are in English, the ones that aren’t will be flagged as such. All the content in this list is public and free, please use them for educational purposes only!
Not all the tools have been tested or reviewed, use them at your own risk! Also, I don’t consider myself a K8s Security expert, I’m just learning and helping others learn along with me. Thanks!
