Open Source Security Podcast

Josh and Kurt talk about some security researchers sort of taking over the .MOBI whois server. The story is a bit sensational, but we ask if it really matters? There are a lot of interesting possible attacks, but turning something like this into a good attack is really hard, maybe impossible. The researchers presented the findings in a very reasonable way.

Josh and Kurt talk to Jay Jacobs about Exploit Prediction Scoring System (EPSS). EPSS is a new way to view vulnerabilities. It's a metric for the likelyhood that a vulnerability will be exploited in the next 30 days. Jay explains how EPSS got to where it is today, how the scoring works, and how we can start to think about including it in our larger risk equations. It's a really fun discussion.

Josh and Kurt talk about Chrome unexpectedly going EOL on Ubuntu 18. Keeping old things alive is really hard to do, and in open source it's becoming more common to just run the latest version rather than trying to keep old versions alive for long periods of time.

Josh and Kurt talk about a story that discusses a story from Black Hat that references supply chains. There's a ton of doom and gloom around our software supply chains and much of the advice isn't realistic. If we want to take this seriously we need to stop obsessing over the little problems and focus on some big problems.

Josh and Kurt talk about a few stories around the TLS CA certificate world. It's all pretty dire sounding. There's not a lot of organization or process in the space, and the root CAs are literally the foundation of modern society, everything needs them to function. There's not a lot of positive ideas here, it's mostly a show where Kurt explains to Josh what's going on, because Josh doesn't want to care (and will continue to ignore all of this going forward).

Josh and Kurt talk about CWE. What is it, and why does it matter. We cover some history, some shortcomings, and some ideas on how CWE could be used to make security a lot better. We frame the future discussion around the OWASP top 10 list. We should be putting more effort into removing removing entire classes of vulnerabilities.

Josh and Kurt talk about a presentation Josh recently gave that was supposed to be about how open source works. The talk was the wrong topic for a security crowd, but there's a lot of interesting details in the questions and comments that emerged. It's clear a lot of security people don't really care about the fine details about what open source is, their primary goal is to help keep development secure.

Josh and Kurt talk about a story talking about the "graying" of open source. There doesn't seem to be many young people working on open source, but we don't really know why that is. There are many thoughts, but a better question is why should anyone get involved in open source anymore? The world has changed quite a lot since open source was created.

Josh and Kurt talk about two documents from the US government that discuss open source in very different ways. The CISA document lays out a way to measure open source, but we take issue with the idea of trying to measure which open source projects are "good". The Whitehouse on the other hand takes an approach that is very open source, get involved. Trying to measure open source isn't producing anything actionable, but getting involved is very actionable, and very much how open source works.

Josh and Kurt talk about a pretty big bug found in CocoPods ownership. We also touch on a paper that discusses the technical debt that open source should have. We discuss what the long term sustainability of open source. There aren't any good solutions for open source today, but talking about these problems is important, we have to start to understand what's going on before we can plausibly discuss solutions. If you're an open source project that needs to put things on pause, or even walk way, that's OK.
