Talk 1

Internet of Cows (IoC) - How to connect cows to the cloud with the help of Apache Kafka

Abstract: This use case is about real time sensor data. Processing data of sensors that are placed inside a cow’s first stomach (rumen) using Apache Kafka , Faust (Kafka Streams like python implementation), Kubernetes and connecting the sensors via LoRaWAN to our self hosted Kafka instance. We are connecting > 140.000 cows with a distributed cloud system, based on a micro service and distributed Architecture.

Speaker: Alexander Oberegger (smaXtec)

Talk 2

Towards Client-Side Field Level Cryptography for Streaming Data Pipelines

Abstract: Apache Kafka offers several security features ranging from authentication and authorization mechanisms to over-the-wire encryption. This notwithstanding, end-to-end encryption between Kafka-based client applications, which fully protects payloads from fraudulent access at the broker's side can still be considered a blind spot. After highlighting the main benefits of explicit data-at-rest protection, this session discusses in-depth how to selectively encrypt and decrypt sensitive payload fields in the context of streaming data pipelines built upon Apache Kafka Connect and ksqlDB apps. In particular, an ecosystem community project named Kryptonite for Kafka - written and open-sourced by the speaker - is introduced. Client-side field-level cryptography makes streaming data pipelines more secure by safeguarding your most sensitive and precious data against any form of uncontrolled or illegal access once it hits the Apache Kafka brokers.

Speaker: Hans-Peter Grahsl (Red Hat)
