Roadblock title:

Outages and oopsies: A look at doing TLS/mTLS wrong and how to do it right


Thursday - 1:00 PM (5th floor - Manchester F)


In the ever-evolving world of cybersecurity, Transport Layer Security (TLS) and Mutual TLS (mTLS) have become essential for secure communication. However, improper implementation and configuration can lead to a cascade of issues, ranging from frustrated engineers to service outages and full-blown security breaches.

This talk takes a lighthearted approach to a serious topic, using real-world examples and relatable anecdotes to explore the most common pitfalls associated with TLS/mTLS deployments. We’ll delve into certificate misconfigurations, deployment mistakes, and other oopsies that can leave your infrastructure team scrambling and your users frustrated. More importantly, we’ll cover how to do TLS/mTLS right to maximize security and minimize maintenance burden.
