I’ve been thinking about this one for a while. I’ve seen some CISOs who are amazing at what they do, and I’ve seen plenty that can’t get anything done. After working with one that I think is particularly good lately, I’ve made some observations that has changed my mind about the modern day CISO reporting structure. The TL;DR of this post is if you have a CISO that claims they can only get their job done if they report to the board or CEO, you have an ineffective CISO. ...
Josh and Kurt talk about the security of applications. We talk about the security of infrastructure all the time, but what happens when we combine infrastructure into an application or solution? https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_202_The_convergence_of_application_security.mp3 Show Notes Picture of Kurt’s security check-up Dragon controls
Josh and Kurt talk about CVSSv3 and how it’s broken. We started with a blog post to explain why the NVD CVSS scores are so wrong, and we ended up researching CVSSv3 and found out it’s far more broken than any of us expected in ways we didn’t expect. NVD isn’t broken, CVSSv3 is. How did we get here? Are there any options that work today? Where should we go next? ...
Josh and Kurt talk to Liz Rice from Aqua Security about container security and her new book on the same topic. What does container security look like today? What are some things you can do now?

Josh and Kurt talk about a grab bag of topics. A DNS security flaw, port scanning your machine from a web browser, and CSV files running arbitrary code. All of these things end up being the result of corner cases. Letting a corner case be part of a default setup is always a mistake. Yes always, not even that one time. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_199_Special_cases_are_special_DNS_Websockets_and_CSV.mp3 Show Notes Bind advisory Robustness Principal eBay port scanning localhost OWASP CSV injection
This blog post originally started out as a way to point out why the NVD CVSS scores are usually wrong. One of the amazing things about having easy access to data is you can ask a lot of questions, questions you didn’t even know you had, and find answers right away. If you haven’t read it yet, I wrote a very long series on security scanners. One of my struggles I have is there are often many “critical” findings in those scan reports that aren’t actually critical. I wanted to write something that explained why that was, but because my data took me somewhere else, this is the post you get. I knew CVSSv3 wasn’t perfect (even the CVSS folks know this), but I found some really interesting patterns in the data. The TL;DR of this post is: It may be time to start talking about CVSSv4. ...
Josh and Kurt talk about the Krebs blog post titled “When in Doubt: Hang Up, Look Up, & Call Back”. In the world of security there isn’t a lot of actionable advice, it’s worth discussing if something like this will work, or ever if it’s the right way to handle these situations. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_198_-_Good_advice_or_bad_advice_Hang_up_look_up_and_call_back.mp3 Show Notes When in Doubt: Hang Up, Look Up, & Call Back Tech Support Scam podcast: Part 1, Part 2 STIR/SHAKEN Drill the wrong safe deposit box 2009 Bank of Ireland robbery Comment on Twitter with the #osspodcast hashtag ...
Josh and Kurt talk about what beer and reproducible builds have in common. It’s a lot more than you think, and it mostly comes down to quality control. If you can’t reproduce what you do, you’re not a mature organization and you need maturity to have quality. https://traffic.libsyn.com/secure/opensourcesecuritypodcast/Episode_197_Beer_security_and_consistency_the_newer_better_triad.mp3 Show Notes Reinheitsgebot Josh’s Blog Post Ken Thompson’s reflections on trusting trust Tor Browser Deterministic Builds One line package broke npm create Donkey Kong 64 memory leak Comment on Twitter with the #osspodcast hashtag ...
Josh and Kurt talk about automatic updates. Specifically we discuss a recent decision by Ubuntu to enable forced automatic updates. There are lessons here for the security community. We have a history of jumping to solutions rather than defining and understanding problems. Sometimes our solutions aren’t the best.

Josh and Kurt talk about the uproar around Cloudflare’s “Is BGP safe yet” site. It’s always interesting watching how much people will push back on new things, even if the new things is probably a step in the right direction. The clever thing Cloudflare is doing in this instance is they are making the BGP problem something anyone can understand.
