Talk 1: Reconsidering the RPKI Trust Model and Validation Algorithm

In this talk Job Snijders from Fastly will explain how to reason about
‘trust’ in context of the RPKI, how the current validation algorithm
works, what the downsides of its rigidity are, and share perspective on
different, more robust approaches. Or, phrased in a more exciting way:
how to prepare for the theft of an RIR’s HSM?!?!

Presenter: Job Snijders (Fastly)

Talk 2: “Reclaiming” 240.0.0.0/4

In IPv4 class E space is magical, in that whenever anybody looks at it seems to have a fantastic opinion on how to reclaim it, This is becoming even more tempting in the era where IPv4 is hard to obtain and IPv6 deployment is frustratingly stubborn. In this talk I will go over the challenges and why it is probably not a good idea to try and use this dormant IPv4 space.

Talk 2: Fabrics

A software engineer’s view into how contemporary hardware operates and what does that mean for network and infrastructure layers, as seen in the context of machine learning hype. Fabrics, in particular non-IP fabrics, routing of address space (no, not IP address space, the real address space), Infiniband and custom transports, feeding accelerators with data and what does that mean for the networking part of the system, and how software could and does abuse the potential of underlying hardware.

Talk 1: From Network Zero to Automation Hero: A Journey in Network Automation

In this presentation I’ll explore my transformative journey in network automation over the past three years. Starting with my departure from a company lacking interest in automation and my subsequent entry into a new role with a visionary boss. Initially plagued by self-doubt and imposter syndrome, my perseverance led me to significant achievements. We implemented NetBox to manage a network inherited from multiple MSPs, paving the way for subsequent automation projects including automating core network deployments using Arista Validated Designs (AVD) and a Django-based firewall management tool called “Forge.”

These tools allowed us to model firewall rules based on device grouping, streamlining configuration and deployment processes and empowering business units by creating a self-service application named “BUG” (Business Unit Generated Firewall Rules) which enabled developers to request firewall rules easily.This journey demonstrates the transformative power of network automation and how my journey can hopefully help others to overcome challenges and drive impactful change in their organization.

Talk 1: Why is the Internet so slow?

A 30 second stop at a Tube station should be enough to attach to WiFi and message your friend, but failure to get his message through sent Perry down a debugging rabbit hole. Join Perry on this journey to uncover why the Internet is just so damn slow.

Talk 2: I am the Captain Now!

When I first watched Hackers in 1998, the idea of being able to remotely control ships seemed rather fanciful. After working on container ships as an engineer in the mid-2000s, it seemed every more unlikely. We didn’t have a full-time Internet connection and all the vital systems were truly air-gapped. But things have changed – ships are becoming more and more connected and complex.   As a result, 15 years later, I found myself sat in my pants on the sofa with the ability to control the steering on one of the world’s largest cruise ships. We’ve been able to brick every PLC across tens of oil rigs, pay for food as the captain, and write rude words on the side of the ship.   To get to this point, we had to go on a learning voyage across tens of different vessels, including offshore support tugs, super yachts, oil rigs and container ships. Join me on a whistle stop tour of what’s on a ship, how it’s all connected together, what threats there are and how we find the vulnerabilities. Lots of little tips and tricks that can help anyone examine industrial control systems, understand how they work, and then have a lot of fun with them!
