**IMPORTANT PLEASE RSVP:** https://www.jug.ch/html/events/2026/data-streaming-security.html \*\*\* ROOM: PH Zürich, Lagerstrasse 2, 8090 Zürich, Building LAB, Room H015 AGENDA: 18:15-19:30h: Talk incl. Q/A * After the talk, you will have the opportunity to exchange ideas and network with the speaker and professional colleagues over beer and rich finger foods. **SPEAKER**: Olena Kutsenko **COMPANY**: [Confluent](https://www.confluent.io/) Data streaming is powering everything from fraud detection and real-time analytics to patient monitoring and order fulfillment. But as the role of streaming grows, so does the risk - because many streaming platforms, like Apache Kafka, aren't secure by default. In this talk, we'll take a practical look at data streaming security through the lens of Kafka, one of the most widely adopted streaming platforms in the world. We'll walk through what can go wrong - real examples of exposing 14M patient-doctor messages, or years of real-time delivery info to the internet - and what it takes to do it right. We'll cover the key pillars of securing a streaming system: encryption in transit and at rest, access control, monitoring, and key management. Along the way, we'll look at the trade-offs like disk encryption vs. end-to-end encryption, what is behind field-level and envelope encryption, and the realities of using customer-managed keys in regulated industries. We'll also explore how streaming security has evolved, how real vulnerabilities (like CVE-2019-12399) highlight the need for patching and monitoring, and what successful multi-layered security looks like in production - from financial institutions to healthcare platforms. If you're building, running, or scaling streaming systems, this talk will help you see the security blind spots and give you concrete steps to protect the data flowing through your pipelines.

### [Info and Registration African Drumming](https://forms.gle/wSUGNXMjHBDSePNaA) ### **African Drumming – Feel the Groove!** Discover the joy of rhythm and community through the vibrant beats of West African drumming. In this course, you’ll learn traditional and modern rhythms on djembes and doundouns (bass drums and bells) — all in a fun, structured, and hands-on way. We’ll explore the essentials of rhythm and groove, from understanding pulse, beat, and cycle to experiencing how different instruments interact in an ensemble. You’ll play, listen, improvise, and even create your own arrangements together with the group. Body percussion exercises help you *feel* rhythm from head to toe, while guided theory inputs deepen your understanding of African musical structures — intros, solos, signals, and more. Our holistic approach connects body, mind, and soul. Through intuitive rhythm games, easy-to-follow exercises, and attention to technique, you’ll build coordination, confidence, and a relaxed, flowing playing style. Structured learning materials (notation and videos) support your practice between sessions — so you can keep the groove going wherever you are! A funny and welcoming group is awaiting YOU! **Reduced rates for holders of IV/AHV and Kulturlegi!** Trial session is possible.

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.
