Biden’s Cyber-Everything Bagel with Carole House
Just a few days before turning off the lights, the Biden administration dropped a huge cybersecurity executive order including a lot of good stuff, that hopefully [cross your fingers, knock wood, spin around three times and spit] will last into future administrations. We snagged some time with Carole House, outgoing Special Advisor and Acting Senior Director for Cybersecurity and Critical Infrastructure Policy, National Security Council in the Biden-Harris White House, to give us a brain dump.And now due to popular demand, with video of our actual human¹ faces! https://youtu.be/Pqw0W2crQiMTranscript: https://securitycryptographywhatever.com/2025/01/20/bidens-cyber-everything-bagel-carole-house/Links:- https://www.federalregister.gov/d/2025-01470- https://www.wired.com/story/biden-executive-order-cybersecurity-ai-and-more/- 2022 EO: https://archive.ph/hvzWd- 2023 EO: https://www.whitehouse.gov/wp-content/uploads/2023/06/M-23-16-Update-to-M-22-18-Enhancing-Software-Security-1.pdf- 2021 EO: https://www.federalregister.gov/documents/2021/05/17/2021-10460/improving-the-nations-cybersecurity- NIST SSDF: https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-218.pdf- https://www.federalregister.gov/documents/2015/04/02/2015-07788/blocking-the-property-of-certain-persons-engaging-in-significant-malicious-cyber-enabled-activities- IEEPA: https://www.govinfo.gov/content/pkg/USCODE-2023-title50/pdf/USCODE-2023-title50-chap35-sec1701.pdf¹ Actual human faces not guaranteed in all cases"Security Cryptography Whatever" is hosted by Deirdre Connolly (@durumcrustulum), Thomas Ptacek (@tqbf), and David Adrian (@davidcadrian)
