**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.

**mit Elana Andermatt und Andrea Bergamini** Beim Kuscheln geht es um Körperkontakt zwischen Menschen. Genauer gesagt, um entspannten, nicht erotischen Körperkontakt. Daher ist es beim Kuscheln auch nicht wichtig, ob das Gegenüber männlich, weiblich oder divers ist. Wir kultivieren beim Kuscheln absichtslose, liebevolle und nährende Berührung. Es soll möglich sein, sich fallen lassen zu können und in einem sicheren, gehaltenen Rahmen im eigenen Körper anzukommen. In verschiedenen sensitiven, achtsamen Begegnungs- und Berührungs-Übungen, bei denen wir uns auf das Berührt-Sein einlassen, werden wir miteinander vertraut. Wir können mit Nähe und Distanz experimentieren und wie es ist, sich an jemanden oder gleich zwei anzukuscheln und dann doch weiterzuziehen oder auch liegenzubleiben und den Körperkontakt zu geniessen. Die „Kuschel-Energie“, das ist der nährende, entspannte Kontakt zu anderen, ohne dass es in erotische oder sexuelle Bereiche abgleitet. Es geht um achtsame und absichtslose Berührungen und den 100%-igen Respekt deiner individuellen Grenzen! Und wenn wir dann beim Zusammenliegen immer weniger tun, sondern nur noch sind, dann kann sich das schon mal wie ein “Kuschelhimmel” anfühlen … * Die Sicherheit des klar strukturierten und geleiteten Abends und gleichzeitig die Freiräume für deine individuellen Bedürfnisse und Grenzen. * Die verschiedenen Ebenen von Kontakt und Verbindung: Berührungen, Worte, der energetische Kontakt (z.B. nur im Augenkontakt) und die Resonanz im Gruppen-Feld. * Die Stärkung von Selbstkontakt, Eigenwahrnehmung und “Gut-zu-sich-selber-sein”, denn der Kontakt zu anderen kann sich nur in dem Masse vertiefen, wie wir den Kontakt zu uns selber vertiefen können. * Die Öffnung für “die grösseren Räume”, die uns auf einer spirituellen Ebene nähren und verbinden, so dass Gefühle von Frieden und „Nach-Hause-kommen“ durch die Gemeinschaft UND durch die Verbindung zum Grösseren genährt werden. * Die ganz persönlichen Momente, in denen du ganz entspannt, offen und echt anderen herzoffenen Menschen begegnest. \*\* Wenn du JA sagst bei deiner Anmeldung, sagst du JA zu den **klaren Kuschelregeln**: * Keine Berührung im Intimbereich und an erogenen Zonen. Keine Küsschen oder Hände unter dem TShirt. Erotische Energie wird nicht angefacht. Wir bleiben auf der Ebene des brüderlichen und schwesterlichen kuscheligen Herzens. * Du kannst dein Tempo jederzeit wählen, wie schnell und nahe du mit anderen sein möchtest oder wie oft du auch Momente für dich alleine brauchst. * Ein NEIN ist ein NEIN. Achte drauf, dass du deine und andere Grenzen des Wohlbefindens respektierst. **Zeiten:** 19:30-22:00h Einlass 19 Uhr bei einer Tasse Tee An FreitagAbenden mit optionaler Verlängerung bis 23h (wer will). **WO:** JupiterSpace, SeminarPavillon vom Jupiterhaus im Frankental; Frankentalerstrasse 55, 8049 Zürich **Mitbringen** bitte bequeme Kleider, warme Socken und bei Bedarf eine verschliessbare Wasserflasche. **Ausgleich:** 30.-, oder das, was du zahlen kannst. **Infos und Anmeldung:** Elana [elana@sensual-healing.ch](mailto:elana@sensual-healing.ch), 079 437 22 22 [https://kuschel-tempel.ch](https://kuschel-tempel.ch) Wenn du regelmässig einen Reminder haben magst, kannst du dich gerne hier zum \*\*[Kuschel-Tempel-Newsletter ](https://kuschel-tempel.ch/#newsletter/)\*\*anmelden. *Sichere, wohlwollende Nähe und Körperkontakt ohne Erwartungs- und Beziehungsdruck, ist eine tief nährende Medizin für unser System.

**Location:** ETH Zürich, near Polyterrasse (Universitätstrasse 6, Building CAB, Room F88) **Event Topic:** One of OpenClaw's great strengths is its direct command-line access to user space—this flexibility enables rapid development of automation workflows without the friction of rigid APIs or sandboxed environments. But by default, this means the agent has plaintext access to all connected service credentials, whether Gmail, Calendar, WhatsApp, or others. This creates a broad attack surface and limits our ability to enforce fine-grained access policies. In this meetup, we'll explore a practical architecture for credential isolation using macOS user spaces. We'll walk through how to deploy separate service proxies, each running in its own user context, to isolate credentials per service. These proxies act as gateways between the OpenClaw agent and your accounts, enabling you to implement arbitrary access policies—rate limiting, scope restrictions, audit logging, or whatever your threat model requires. The good news: this architecture is simple enough to vibecode. You don't need deep systems expertise to get started—we'll show you how to scaffold the setup quickly and iterate from there. Whether you're running OpenClaw for personal automation or exploring agent deployments in more sensitive contexts, this session will give you hands-on techniques for tightening your security posture without sacrificing the rapid iteration that makes OpenClaw powerful.

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.
