Kafka Security up to date matrials

Ops
1

Greetings,
I’m learning about security, how to set up and use SSL. There are many materials out there and I’m curious if these are up to date:
Encryption and authentication → Encrypt and authenticate Confluent Platform and resources with TLS | Confluent Documentation
using SSL with confluent docker images: Clustered Deployment Using SSL | Confluent Platform 3.3.0
If you have better resources to share, please don’t hesitate

Kafka Definitive Guide is a free ebook (can be downloaded from the Confluent page somewhere) which is a pretty good resource for Kafka ops. It’s indeed a bit dated (3-4 years?), but I don’t think that much has changed in regards to the security.

Thanks @weeco . I do have that book, but it was written 3 years ago, so I thought it might have been outdated. I also think that there is not much changes in the security.
