It&rsquo;s such a broad topic that I could approach it from many different angles: fundamental concepts and common misconceptions, different tools, practical use cases, existing research studies, and much more &mdash; and before I knew it, what started as a blog post could have turned into an entire research paper 🙈. Instead of aiming for a complete study from the start, I wanted to take a fast, hands-on approach with <a href="https://tetragon.io">Tetragon</a>. Similar to my previous one-week challenge on <a href="../aya_init">Aya</a>, I gave myself another seven-day challenge to learn, experiment, and document how far I could get.</p>
