I listen to a lot of podcasts. A lot of podcasts. I was listening to the Dave and Gunnar Show podcast episode 212 with guest David A. Wheeler. The Titanic was used as an example of changing process after a security incident. This opened up a flood of thoughts to me, but not for the reasons intended in the conversation. The point of the suggestion was the Titanic sinking created changes to international requirements to help avoid a similar disaster next time, and we should be viewing SolarWinds in a similar way. The idea being we should use the SolarWinds event to drive meaningful change to make security better. Why no change will come of this is a different conversation: TL;DR it’s because nobody important died from SolarWinds, the Titanic killed a lot of important people. But I think this is an interesting way to talk about how we tend to deal with problems in software and how we deal with them in real life. ...

Josh and Kurt talk about the Google Project Zero report titled “A Year in Review of 0-days Exploited In-The-Wild in 2020”. It’s a cool report but we don’t agree on the conclusion. The answer isn’t to security harder, it’s to stop using C. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_258_Stop_using_C.mp3 Show Notes Google Project Zero Year of 0-days Kurt’s CUPS tweet

I’ve been thinking about what open source is a lot lately. I mean A LOT, probably more than is healthy. There have been a ton of open source happenings in the world and the discussions around open source licenses have been numerous. There are even a lot of discussions around the very idea of open source itself. What we once thought was simple and clear is not simple or clear it would seem. ...

What a year it’s been! I feel like 2021 went by like a … it’s still January??? So it’s pretty much impossible to ignore any of the events of the last month. I want to talk about something that’s near and dear to my heart, and in the news, not for a good reason. Software supply chains. This is probably a dreadful topic to most, but I love software supply chains. I was talking about them before anyone was even thinking about them. I’m not going to pull a “get off my lawn” here, I think it’s cool everyone is starting to care. I want to talk about how to be realistic about your supply chain. Almost all advice I’ve seen of the last month has been terrible, so I’m going to also give some terrible advice. ...

Josh and Kurt talk about what we can stop doing. We take a position of asking “does it spark joy” for tools and infrastructure. Everyone is doing something they should stop. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_255_What_if_security_wasnt_joyless.mp3 Show Notes Does it spark joy?

Josh and Kurt talk about the new right to repair rules in the EU. There’s a strange line between loving the idea of right to repair, but also being horrified as security people at the idea of a device being on the Internet for 30 years. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_254_Right_to_Repair_Security.mp3 Show Notes EU right to repair repair.eu

Josh and Kurt talk about this idea that seems to exist in security of “attackers only need to be right once” which is silly. The reality is attackers have to get everything right, defenders really only need to get it right once. But “defenders only need to be right once” isn’t going to sell any products. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_253_Defenders_only_need_to_be_right_once.mp3 Show Notes Richard Feynman and manhole covers Richard Feynman on Why He Can’t Tell You How Magnets Work Israeli airport security FAA stolen sweater XKCD Is it worth the time CGP Grey The trouble with transporters
