Who's the Bigger Cybersecurity Risk – Microsoft or Open Source?

There's a whiff of Auld Lang Syne about episode 500 of the Cyberlaw Podcast, since after this it will be going on hiatus for some time and maybe forever. (Okay, there will be an interview with Dmitri Alperovich about his forthcoming book, but the news commentary is done for now.) Perhaps it's appropriate, then, for our two lead stories to revive a theme from the 90s – who's better, Microsoft or Linux? Sadly for both, the current debate is over who's worse, at least for cybersecurity.   Microsoft's sins against cybersecurity are laid bare in a report of the Cyber Security Review Board, Paul Rosenzweig reports.  The Board digs into the disastrous compromise of a Microsoft signing key that gave China access to US government email. The language of the report is sober, and all the more devastating because of its restraint.  Microsoft seems to have entirely lost the security focus it so famously pivoted to twenty years ago. Getting it back will require a focus on security at a time when the company feels compelled to focus relentlessly on building AI into its offerings.  The signs for improvement are not good.  The only people who come out of the report looking good are the State Department security team, whose mad cyber skillz deserve to be celebrated – not least because they've been questioned by the rest of government for decades.   With Microsoft down,  you might think open source would be up.  Think again, Nick Weaver tells us.  The strategic vulnerability of open source, as well as its appeal, is that anyone can contribute code to a project they like.   And in the case of <a title= "Original URL: https://urldefense.com/v3/__https:/www.wired.com/story/jia-tan-xz-backdoor/__;!!ApXA7kLm!1UfhP2XB7OY1fje8f5sJz6LcdK0a0yUjr5plXK4VWTYMdfi5kdVp-Te6Aryp-0PPeubBCAvNV0iso39O7a4pF2F0LmpYD1EI_hU$ Click to follow link." href= "https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Furldefense.com%2Fv3%2F__https%3A%2Fwww.wired.com%2Fstory%2Fjia-tan-xz-backdoor%2F__%3B!!ApXA7kLm!1UfhP2XB7OY1fje8f5sJz6LcdK0a0yUjr5plXK4VWTYMdfi5kdVp-Te6Aryp-0PPeubBCAvNV0iso39O7a4pF2F0LmpYD1EI_hU%24&data=05%7C02%7Ctanwilb%40iu.edu%7Cab3fbc13de714adc81be08dc5998a48f%7C1113be34aed14d00ab4bcdd02510be91%7C0%7C0%7C638483759336138944%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=dCjwi68AVBSfW%2BBZ9OGGU52
