Josh and Kurt talk about a tweet from @kmcquade3 asking the question “What’s a concept in security that is generally accepted as true but is actually bull%$#*?” How many of the replies make sense?

Josh and Kurt talk about leap seconds. Every time there’s a leap second, things break. Facebook wants to get rid of them because they break computers, but Google found a clever way to keep leap seconds without breaking anything. Corner cases are hard, security is often just one huge corner case. There are lessons we can learn here. https://traffic.libsyn.com/opensourcesecuritypodcast/Episode_334_Leap_seconds_break_everything.mp3 Show Notes How and why the leap second affected Cloudflare DNS Facebook wants to get rid of leap seconds Leap Smear Falsehoods programmers believe about time

Josh and Kurt talk about Microsoft creating a policy of not allowing anyone to charge for open source in their app store. This policy was walked back quickly, but it raises some questions about how fair or unfair open source really is. It’s mostly unfair to developers if you look at the big picture. https://traffic.libsyn.com/opensourcesecuritypodcast/Episode_333_Open_Source_is_unfair.mp3 Show Notes Syft Grype Microsoft bans and unbans open source Tidelift survey Bruce Perens - What comes after open source

Josh and Kurt talk about PyPI mandating two factor authentication for the top 1% of projects. It feels like a simple idea, but it’s not when you start to think about it. What problems does 2FA solve? How common are these attacks? What are the second and third order effects of mandating 2FA? This episode should have something for everyone on all sides of this discussion to violently disagree with. https://traffic.libsyn.com/opensourcesecuritypodcast/Episode_332_PyPI_2FA_or_not_2FA_that_is_the_question.mp3 Show Notes PyPI announcement NPM expired domains Morten Linderud Tweet Congratulations: We Now Have Opinions on Your Open Source Contributions

Josh and Kurt talk about their very silly GPG key management from the past. This is sadly a very true story that details how both Kurt and Josh protected their GPG keys. Josh’s setup is like something out of a very bad spy novel. It was very over the top for a key that really didn’t matter. https://traffic.libsyn.com/opensourcesecuritypodcast/Episode_331_GPG_but_nothing_makes_sense.mp3 Show Notes XKCD signed email Shire calendar Guardian editors destroy Snowden laptop

Josh and Kurt talk about the challenge of dealing with vulnerabilities at a large scale. We tend to treat every vulnerability equally when they are not equal at all. Some are trees we have to pay very close attention to, and some are part of a larger forest that can’t be treated as individual vulnerabilities. We often treat risk as a binary measurement instead of a sliding scale. https://traffic.libsyn.com/opensourcesecuritypodcast/Episode_330_The_sliding_scale_of_risk_seeing_the_forest_for_the_trees.mp3 Show Notes gsd.id The Register OpenSSL story OpenSSL bug

Josh and Kurt talk about what the actual purpose of signing artifacts is. This is one of those spaces where the chain of custody for signing content is a lot more complicated than it sometimes seems to be. Is delivering software over https just as good as using a detached signature? How did we end up here, what do we think the future looks like? This episode will have something for everyone to complain about! ...

Josh and Kurt talk about the security of employees leaving jobs. Be it a voluntary departure or in the context of the current layoffs we see, what are the security implications of having to remove access for one or more people departing their job? https://traffic.libsyn.com/opensourcesecuritypodcast/Episode_328_The_Security_of_Jobs_or_Job_Security.mp3 Show Notes Tesla Layoffs Coinbase layoffs

Josh and Kurt talk about a funny GitHub reply that notified 400,000 people.

Josh and Kurt talk about containers. There are a lot of opinions around what type of containers is best. Back when it all started there were only huge distro sized containers.
