Cybersecurity & Compliance Analyst with a strong background in Linux systems, networking, and backend development.

Currently working on cloud infrastructure, security standards (SOC 2, ISO 27001), and distributed systems. Passionate about understanding how systems actually work beyond abstractions, from operating systems internals to real-world production environments.

Also runs a technical content platform (VT Security) focused on cybersecurity, Linux, and systems thinking, helping engineers bridge the gap between theory and practice.

Abstraction Leaks: Why Understanding Linux Internals Still Matters

Modern software engineering heavily relies on abstractions: containers, cloud platforms, frameworks, and managed services. While these abstractions accelerate development, they often hide the underlying complexity of the system. This talk explores what happens when those abstractions break — and why understanding Linux internals becomes essential.

This session is aimed at developers, DevOps engineers, and newcomers to Debian who want to deepen their understanding of how systems actually work. Using real-world examples from networking, process management, and resource handling, we will explore how abstraction leaks manifest in production environments.

Attendees will leave with a clearer mental model of Linux systems, an appreciation for Debian’s philosophy of transparency and control, and practical insights on how to debug, reason about, and design more resilient systems by understanding what lies beneath the abstraction layers.
