Facing the Reality of Risk Prioritization - Bianca Lewis (BiaSciLab), Dan DeCloss - PSW #819

On February 27, 2024, PCAST (President’s Council of Advisors on Science and Technology) sent a report to the President with recommendations to bolster the resilience and adaptability of the nation’s cyber-physical infrastructure resources. Phil was part of the team that worked on the report and comes on the show to talk about what was recommended and how we implement the suggestions. This week the crew discusses: When TVs scan your network, bad things can happen, PuTTY is vulnerable, Crush FTP, vulnerabilities that will never be fixed, CVEs are for vulnerabilities silly, you can test for easily guessable passwords too, FlipperZero can steal all your passwords, more XZ style attacks, more reasons why you shouldn't use a smart lock, and your keystrokes are showing!

Version 4.0 of the Payment Card Industry Data Security Standard (PCI DSS) puts greater emphasis on application security than did previous versions of the standard. It also adds a new “customized approach” option that allows merchants and other entities to come up with their own ways to comply with requirements, and which also has implications for application security. Specifically, PCI DSS 4.0 requires that by March 31, 2025, more testing of public-facing applications related to payment processing or other activities be considered “in scope” for compliance. Generally, any system that touches payment-card data is in scope for PCI DSS compliance, whether or not the system or function is public-facing. We'll talk through what organizations should have gotten done by March 31, 2024, and what needs to happen by March 31, 2025.
