Talk 1: Reducing The Impact of IPv6 Flash Renumbering Events

Providing fixed, static IPv6 prefixes is not always a viable option for ISPs, but dynamic prefixes can also introduce problems. The IETF has recently published, and is still working on, several documents to help mitigate the impact of what’s referred to as an IPv6 “Flash renumbering event”.

Talk 1: Prometheus for network user experience (and not only) monitoring

Quite a few times I’ve had to deal with requests stating that there is a network problem in a remote branch location, preventing office employees from doing their job, whereas monitoring systems were showing literally nothing unusual. In order to solve the problem I have built a monitoring system leveraging Prometheus to show user experience, which started my journey to start building my own exporters. I would like to share my experience to show network engineers where Prometheus could be helpful, what the challenges are, and how to overcome them.

Talk 2: BGPsec in the context of routing system security

BGPsec enjoys global world domination. Or does it? No, it does not. At least not yet. Therefore this needs to be addressed.

BGPsec has been around in theory and on paper for a while. Not in practice and deployments, though. Some production scale and quality experimentation with BGPsec has revealed quite a number of incorrect design time assumptions, outright wrong decisions made, lack of community understanding of how it could and should be used, and how can it fit into the overall routing security framework. One of the open gaps is the unawareness of the community, primarily operations community, of how BGPsec functions and how it should be deployed.

This talk covers three main areas:

– BGPsec the protocol, covering the protocol mechanics itself and how it operates on the BGP signaling level;
– Infrastructure required for BGPsec operation, covering aspects of providing and distributing supporting informational elements into BGPsec system – integration with RPKI machinery, what is required from the perspective of registries and certificate authorities, what are the scalability properties expected from the RPKI side, and practical aspects of how existing origin and path validation tooling would need to be extended to cover BGPsec too;
– BGPsec in the context of the overall routing security, and how it would match or interwork with the current understanding of routing security as realized by origin and path validation, with specific scenarios of what it would take to deploy BGPsec from the perspective of edge node, transit operator, an IX, and a CSP.

Talk 1: Anchoring networking in cryptography: what’s next?

Job Snijders, hacker @ Fastly & OpenBSD, figurehead at PeeringDB & Ripe NCC, allround routing security badass – will share with us his perspective on how cryptography is becoming more and more intertwined with the Internet’s global routing system.

Talk 2: bgp.tools – how hard can it be

Want to know what makes sites like bgp.he.net or bgp.tools tick? or why they seem inaccurate at times? How does AS Rank even work? and why the
speaker spends seemingly unlimited amounts of his time staring at whois? Then this is the talk for you!

After Talks: Networking for Networkers

Stay around after the talks for a social hour.

Location: Zoom

We will once again be combining powers with our NetMcr friends for a joint meeting. We’ll be starting at the slightly later (by NetLdn standards) time of 1930hrs UTC+0.

The meeting will be held online using Zoom. The meeting room ID and password will be shared on the evening of the event, to the NetLdn mailing list and in the NetLdn Slack, 1 hour before the event starts.

Please set your full name in the Zoom client before joining the meeting, they will be validated for admission.

Join from 1915hrs (UTC+0) onward, talks begin promptly at 1930hrs (UTC+0).

Talk 1: DDoS Attacks via Laundered DNS Traffic

Marek will be talking about DDoS attacks that rely on some well know public DNS services.

Presenter: Marek Isalski

Talk 2: Bruteforcing Android PINs

What if I told you that in 2022 you could still brute-force the PIN on an Android phone? I will show you how to turn your Kali Nethunter phone into a brute-force PIN cracking machine. Unlike other methods this works on phones out of the box, so you won’t need ADB access to your locked phone, or to have previously rooted the Operating System.

While not every phone is vulnerable, many are, and the version of Android doesn’t matter. Although Android itself is reasonable secure, each handset manufacturer has made their own lock-screen with custom brute-force protection and some of them are easily cracked.

Talk 1: 5G Private Networks: what are they and why are they needed?

Andy’s here to speak to us about 5G Private Networks. If you’ve ever wondered why our favourite vendors keep talking about running a self-contained 5G network instead of an equivalent WiFi network, then this is definitely a talk you’ll enjoy. Andy has decades of radio network experience, as well as hands-on experience with the emerging technology in this space, and we’re sure that this talk will be well worth your time.

Presenter: Prof. Andy Sutton
