Introduction When auditing a Kubernetes cluster for the first time, whether as part of an internal pentesting exercise, a configuration review, or simply to understand what is running in production, most of the real problems do not show up in fancy automated scanners but in patient reading of the cluster state. Excessive permissions, privileged containers nobody remembers deploying, secrets in environment variables, TLS certificates about to expire, and hostPath volumes mounting sensitive node paths are recurring findings that anyone can detect with kubectl and a bit of method. ...

Introduction 5G is the fifth generation of mobile networks, designed to surpass 4G significantly in speed, capacity, and latency. Its objective is not limited to just browsing the internet faster, but to enable entirely new applications, such as autonomous vehicles, augmented reality, real-time telemedicine, and millions of connected devices simultaneously in the Internet of Things (IoT). In technical terms, 5G is characterized by three main pillars: eMBB (enhanced Mobile Broadband) for high-speed and large-capacity connections, URLLC (Ultra-Reliable Low Latency Communications) for critical communications with minimal latency, and mMTC (massive Machine-Type Communications) for efficiently connecting millions of IoT devices. ...
