If you are living in The Netherlands, by now, you may well have noticed the amount of open water. If you enjoy cycling in the city, you may wish to feel safer as you navigate the bridges and canals. And you may also want to get ready for visiting the beach, pools or the many lakes this summer. Learning how to swim takes approx 1 year and it all starts with the very first lesson. New comers enroll via our website and pay € 30,50, this is the first lesson and a goody bag. After the class you agree with the personal swim coach how to continue to obtain your final objectives. Enrolling is only possible via [www.your-personal-swim-coach.nl ](https://www.your-personal-swim-coach.nl/)hence a rvsp via meetup is not enough.

**Um was geht es dieses mal?** Dieses Mal dreht sich alles um aktuelle Herausforderungen, Best Practices und Trends rund um IT-Sicherheit. Freut euch auf praxisnahe Einblicke, spannende Diskussionen und den Austausch mit Security-Expert:innen. **So leicht können Hacker Ihr Unternehmen über öffentliche Daten angreifen - Mehmet Avci (codecentric)** Jedes Unternehmen hinterlässt einen digitalen Fußabdruck – oft unbemerkt, aber öffentlich zugänglich. Genau diese frei verfügbaren Informationen machen sich Angreifer im Rahmen von Open Source Intelligence (OSINT) zunutze, um gezielte Angriffe vorzubereiten, ohne dabei technische Schutzmechanismen direkt angreifen zu müssen. In diesem Talk wird gezeigt, wie einfach es für Angreifer ist, Unternehmen allein auf Basis öffentlich verfügbarer Daten zu analysieren und zu kompromittieren. Nach einer Einführung in die Grundlagen von OSINT und die typischen Phasen eines OSINT‑Prozesses werden verschiedene Techniken vorgestellt und eingeordnet. Dazu gehören unter anderem Subdomain‑Enumeration, Google Dorking, die Auswertung von Unternehmensinformationen, Social‑Media‑Analysen, das Sammeln von E‑Mail‑Adressen sowie die Nutzung von Datenlecks und Breach‑Daten. Anhand praxisnaher Beispiele aus realen Szenarien wird verdeutlicht, wofür diese Techniken eingesetzt werden und wie Angreifer die gewonnenen Informationen miteinander kombinieren, um detaillierte Profile von Organisationen, Infrastrukturen und Mitarbeitenden zu erstellen. Der Vortrag schärft das Bewusstsein dafür, wie aus scheinbar harmlosen Einzeldaten ein ernstzunehmendes Sicherheitsrisiko entstehen kann – und warum OSINT ein zentraler Bestandteil moderner Angriffe ist. **This is fine - until it's not - Christian Uhsat (codecentric)** Was passiert, wenn was passiert? Erfahrungsberichte aus Digitaler Forensik und Incident Response im Kampf gegen Cybercrime, Ransomware und den allgemeinen Wahnsinn. **Hybrides Setup!** Wir freuen uns, euch bei uns in den Räumen der codecentric AG in Dortmund willkommen zu heißen. Vor Ort versorgen wir euch mit Snacks und Getränken und freuen uns gleichzeitig über interessante Diskussionen und einen guten Austausch. Für alle, die es nicht zu uns ins Office schaffen, werden wir das Meetup Hybrid durchführen. Der Stream beginnt ca. 10 Minuten später, damit wir vor Ort ausreichend Möglichkeit für persönliches Kennenlernen haben. Den Live-Stream findet ihr auf dem [YouTube-Channel ](https://www.youtube.com/@codecentricAG)der codecentric AG. **Wichtig - Absage bitte rechtzeitig:** Wir bestellen das Essen bereits 3 Tage vor dem Meetup. Falls ihr doch verhindert sein solltet, bitten wir euch um eine rechtzeitige Absage. Das ist wichtig, damit wir nicht unnötig Essen verschwenden müssen. Vielen Dank für euer Verständnis! **Anreise:** Per Zug: Vom Dortmunder HBF sind es ca. 10 Minuten zu Fuß. Mit dem Auto: Rund um das Office gibt es einige Parkflächen, dazu befinden sich in dem Parkhaus der Thier-Galerie weitere Parkplätze.

We’re heading out for a beautiful cross border hike through forest, heathland, open landscapes, and a very special midpoint stop: **De Achelse Kluis**, a historic abbey on the border between the Netherlands and Belgium. The hike starts in the Netherlands and takes us through the peaceful **Leenderbos**, one of the most atmospheric forest areas in North Brabant. Expect woodland paths, sandy tracks, heath, open views, and that lovely Veluwe style feeling of moving between forest and open landscape. As we continue south, we make our way toward the Belgian border and our main break location: **De Achelse Kluis**. This unique abbey complex lies between **Hamont Achel** and **Leende**. With roots going back to the 17th century, and later known as a Trappist abbey, it offers a beautiful neogothic setting with a brasserie, abbey shop, and a calm historic atmosphere. After several kilometers of forest and heathland walking, arriving at the abbey will feel like a real reward. We’ll take our longer break here, with the option to enjoy the brasserie, have a coffee, try Limburgse vlaai, taste an abbey beer, or simply relax around the grounds. After the break, we cross back into the Dutch side and return through the Leenderbos, completing a full loop through forest, heathland, and quiet countryside. A hike with forest energy, abbey atmosphere, monks’ history, and a touch of Belgium. 📲 **WhatsApp group** I’ll open a temporary WhatsApp group for everyone signed up before the hike, so we can coordinate carpooling, final break arrangements, and any last minute updates. **📍When and where to meet?** We’ll meet at 11h15 at Busstop "Leende, Valkenswaardseweg/A2"" https://maps.app.goo.gl/Uij4AmfEos2foDbQ8 ⏰ **We start walking a few minutes after meeting up** We don’t wait for latecomers, as we have a long route ahead and want to enjoy the full day properly. **🚗 Coming by car?** Please check your parking options beforehand so you arrive on time. **⏸️ Planned Breaks** After around **10 km:** 60 minute break at **De Achelse Kluis** I still need to confirm the practical arrangements with the brasserie, including whether we can just have drinks or whether we need to order food as well. I’ll share the update in the WhatsApp group once confirmed. **💸 Payment** Please pay as soon as you sign up: To keep things fair for everyone, if we don’t receive your payment within 48 hours, we will need to remove you from the participant list. If there’s a waiting list, this will happen sooner (in less than 48 hours). If that happens, no worries — you’re always welcome to sign up again if there’s space. 🌟 Early Bird Deal!

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
