Kubernetes Data Exfiltration: Why NetworkPolicies Fall Short and What OVN Adds If you’re running workloads in Kubernetes and relying solely on NetworkPolicies to keep data safe, you’ve got a gap in your defenses — and attackers know it. This guide is for platform engineers, security architects, and DevSecOps teams who are responsible for locking down Kubernetes clusters and want to go beyond the basics. If you’ve already set up NetworkPolicies and assumed that was enough, this is the piece that’ll change your thinking. Here’s what we’re going to dig into: Where Kubernetes NetworkPolicy limitations leave you exposed — specifically around egress traffic and DNS-based exfiltration that standard policies simply can’t catch What Open Virtual Network (OVN) actually adds to Kubernetes network security — not just in theory, but in practical enforcement capabilities that native policies don’t have How to build a layered Kubernetes defense...

Stop Finding Out About AWS Outages After Your Users Do If you’ve ever learned about an AWS service disruption from a frustrated user instead of your own monitoring system, this guide is for you. DevOps engineers, cloud architects, and platform teams who run workloads on AWS need real-time AWS Health alerts the moment something goes wrong — not minutes later when the damage is already done. Setting up an AWS Lambda notification pipeline that pushes AWS Health event notifications directly into Slack or Microsoft Teams puts your team in the driver’s seat, every time. Here’s what we’ll walk through: How AWS Health monitoring actually works and why polling dashboards manually just doesn’t cut it for fast-moving incidents Building the event-driven notification pipeline using AWS Lambda, EventBridge, and the AWS Health API to capture and route alerts automatically Connecting everything to Slack and Microsoft Teams using webhooks so your team gets the ri...
