๐Ÿฆ‘What is eBPF? ๐Ÿคทโ™‚๏ธ

With Cisco Hypershield being talked about EVERYWHERE, wouldn't it be great to know a little more about the technology that the solution is predominantly built around?

eBPF (extended Berkeley Packet Filter) is a technology that lets you run secure programs within the operating system kernel. This unlocks incredible power to monitor and control systems at a granular level, without the overhead of traditional methods.

Why eBPF Matters:

โ€ข ๐—จ๐—ป๐—น๐—ฒ๐—ฎ๐˜€๐—ต๐—ฒ๐˜€ ๐—œ๐—ป๐—ป๐—ผ๐˜ƒ๐—ฎ๐˜๐—ถ๐—ผ๐—ป: eBPF allows developers to extend kernel functionality without modifying kernel code, enabling rapid innovation in networking, security, and observability.
