Presenters Hemanth Malla Source CiliumCon NA 2025 Unleashing the Power of eBPF: Cilium’s DNS Parsing Revolution 🚀 Hey tech enthusiasts! Ever found yourself frustrated by network policies that feel a bit… clunky? Especially when dealing with those ever-changing IP addresses tied to domain names? Well, get ready for some exciting news! Hemanth, a rockstar Cilium CNCF maintainer and principal engineer at Microsoft on the Azure container networking team, has just dropped a bombshell: Cilium can now parse DNS directly within eBPF! This isn’t just an incremental update; it’s a leap forward that promises to transform how we handle FQDN (Fully Qualified Domain Name) network policies. ...

Presenters Dor Serero Michael Katchinskiy Source OpenSource SecurityCon NA 2025 Kubernetes Security: Beyond the CVEs, Mastering the Boundaries 🛡️ Kubernetes. It’s the engine powering so much of our modern cloud-native world. But with great power comes great responsibility, and let’s be honest, security can feel like a labyrinth. This presentation dives deep into the heart of Kubernetes vulnerabilities, not to get lost in the weeds of every single exploit, but to extract the real lessons and equip us with the proactive controls to build truly resilient environments. The core message is clear: we’re seeing a recurring pattern of vulnerabilities, and by understanding these patterns and fortifying our boundaries, we can get ahead of the game. ...

Presenters Anmol Krishan Sachdeva Paras Mamgain Source CiliumCon NA 2025 Building a Digital Fortress: Your Network’s Immune System for Multi-Cluster Meshes 🛡️ In today’s hyper-connected digital world, especially within complex multi-cluster mesh environments, a single compromised pod can quickly escalate from a minor hiccup to a full-blown crisis. Traditional security approaches, often playing catch-up with human intervention, are simply no match for the lightning-fast execution of modern cyberattacks. But what if our networks could defend themselves, proactively and autonomously? That’s the exciting vision Anmol Krishan Sachdeva painted, advocating for the creation of a network immune system. ...
