With hybrid mesh firewalls being the latest trend, and distributed firewalls (like Cisco's Hypershield) emerging in the market. Understanding how Kubernetes transforms traditional IP networking concepts into a dynamic, software-defined environment is crucial. This article demystifies Kubernetes security, making it accessible for network engineers familiar with ACLs and VLANs. You may think this doesn't apply to you, but if you're planning a firewall refresh anytime soon, then these concepts will need to be part of your vernacular going forward.

At its core, eBPF Programs are at the heart of how eBPF views and controls traffic. The eBPF technology is composed of bytecode that the kernel executes in response to specific events (a.k.a event-driven execution). Meaning the eBPF programs can be attached to various hook points in the kernel, allowing them to run in response to a specific event in the kernel. There's a lot of possibilities that stem from this event-driven execution. So many in fact, that eBPF was dubbed by Brendan Gregg as "superpowers for Linux!"

The Extended Berkeley Packet Filter (eBPF) is a tech innovation that allows user space applications to join the high-speed action of the operating system's kernel. It enables faster security operations and real-time policy tuning, acting as a force multiplier and boosting efficiency and adaptability by allowing user space functions to transition into kernel space.
