Developing Open Source Skills for Maintaining Projects - Kat Cosgrove - ASW #361

Open source projects benefit from support that takes many shapes. Kat Cosgrove shares her experience across the Kubernetes project and the different ways people can make meaningful contributions to it. One of the underlying themes is that code is written for other people. That means PRs need to be understandable, discussions need to be enlightening, documentation needs to be clear, and collaboration needs to cross all sorts of boundaries.

Interview Segment: Tony Kelly Illuminating Data Blind Spots As data sprawls across clouds and collaboration tools, shadow data and fragmented controls have become some of the biggest blind spots in enterprise security. In this segment, we’ll unpack how Data Security Posture Management (DSPM) helps organizations regain visibility and control over their most sensitive assets. Our guest will break down how DSPM differs from adjacent technologies like DLP, CSPM, and DSP, and how it integrates into broader Zero Trust and cloud security strategies. We’ll also explore how compliance and regulatory pressures are shaping the next evolution of the DSPM market—and what security leaders should be doing now to prepare.

Topic Segment: We've got passkeys, now what? Over this year on this podcast, we've talked a lot about infostealers. Passkeys are a clear solution to implementing phishing and theft-resistant authentication, but what about all these infostealers stealing OAuth keys and refresh tokens? As long as session hijacking is as simple as moving a cookie from one machine to another, securing authentication seems like solving only half the problem. Locking the front door, but leaving a side door unlocked. After doing some research, it appears that there has been some work on this front, including a few standards that have been introduced: DBSC (Device Bound Session Credentials) for browsers DPoP (Demonstrating Proof of Possession) for OAuth applications We'll address a few key questions in this segment: 1. how do these new standards help stop token theft? 2. how broadly have they been adopted?

Organizations rely heavily on Salesforce to manage vasts amounts of sensitive data, but hidden security risks lurk beneath the surface. Misconfigurations, excessive user permissions, and unmonitored third party integrations can expose this data to attackers. How do I secure this data? Justin Hazard, Principal Security Architect at AutoRABIT, joins Business Security Weekly to discuss the security challenges of Salesforce. Justin will discuss how proactive oversight and a strong security posture in Salesforce requires additional capabilities, including: Continuous monitoring of your Salesforce environment, Strict access controls of Salesforce users, and Automated backup of sensitive data. Think your data in Salesforce is safe and secure, think again. This segment is sponsored by AutoRABIT. Visit https://securityweekly.com/autorabit to learn more about them!

The MCP standard gave rise to dreams of interconnected agents and nightmares of what those interconnected agents would do with unfettered access to APIs, data, and local systems. Aaron Parecki explains how OAuth's new Client ID Metadata Documents spec provides more security for MCPs and the reasons why the behavior and design of MCPs required a new spec like this.

Interview with Danny Jenkins: How badly configured are your endpoints? Misconfigurations are one of the most overlooked areas in terms of security program quick wins. Everyone freaks out about vulnerabilities, patching, and exploits. Meanwhile, security tools are misconfigured. Thousands of unused software packages increase remediation effort and attack surface. The most basic misconfigurations lead to breaches. Threatlocker spotted this opportunity and have extended their agent-based product to increase attention on these common issues.

Interview with Wendy Nather: Recalibrating how we think about AI AI and the case for toxic anthropomorphism. When Wendy coined this phrase on Mastodon a few weeks ago, I knew that she had hit on something important and that we needed to discuss it on this podcast. We were lucky to find some time for Wendy to come on the show! Quick note: while this was not a sponsored segment, 1Password IS currently a sponsor of this podcast. That doesn’t really change the conversation any, except that I have to be nice to Wendy. But why would anyone ever be mean to Wendy???
