Modern AppSec: OWASP SAMM, AI Secure Coding, Threat Modeling & Champions - Sebastian Deleersnyder, Dustin Lehr, James Manico, Adam Shostack - ASW #362
Application Security Weekly (Audio)
Using OWASP SAMM to assess and improve compliance with the Cyber Resilience Act (CRA) is an excellent strategy, as SAMM provides a framework for secure development practices such as secure by design principles and handling vulns. Segment Resources: As genAI becomes a more popular tool in software engineering, the definition of “secure coding” is changing. This session explores how artificial intelligence is reshaping the way developers learn, apply, and scale secure coding practices — and how new risks emerge when machines start generating the code themselves. We’ll dive into the...

Developing Open Source Skills for Maintaining Projects - Kat Cosgrove - ASW #361
Application Security Weekly (Audio)
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.

Making OAuth Scale Securely for MCPs - Aaron Parecki - ASW #360
Application Security Weekly (Audio)
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.

Making TN Critical Infrastructure the Most Secure in the Nation - T. Gwyddon 'Data' ("Gwee-thin") Owen, James Cotter - ASW #359
Application Security Weekly (Audio)
For OT systems, uptime is paramount. That's a hard rule that makes maintaining, upgrading, and securing them a complex struggle. Tomas "Data" Owens and James Cotter discuss how Tennessee is tackling the organizational and technical challenges that come with hardening OT systems across the state. Those challenges range from old technology (like RS-232 over Wi-Fi!?) to limited budgets. They talk about the different domains where OT appears and provide some examples of how the next generation of builders and breakers can start learning about this space.

Figuring Out Where to Start with Secure Code - ASW #358
Application Security Weekly (Audio)
What are your favorite resources for secure code? Co-hosts John Kinsella and Kalyani Pawar talk about the reality of bringing security into a business. We talk about the role of the OWASP Top 10 and the OWASP ASVS in crafting security programs. And balance that with a discussion in what's the best use of everyone's time -- developers and appsec folks alike -- in crafting code that's secure by design rather than just secure from scanner results.

Secure Coding as Critical Thinking Instead of Vulnspotting - Matias Madou - ASW #357
Application Security Weekly (Audio)
Secure code should be grounded more in concepts like secure by default and secure by design than by "spot the vuln" thinking. Matias Madou shares his experience in secure coding training and the importance of teaching critical thinking. He also discusses why critical thinking is so closely related to threat modeling and how LLMs can be a tool for helping developers get beyond the superficial advice of, "Think like an attacker."

Ransomware, Defaults, and Proactive Defenses - Rob Allen - ASW #356
Application Security Weekly (Audio)
Just how bad can things get if someone clicks on a link? Rob Allen joins us again to talk about ransomware, why putting too much attention on clicking links misses the larger picture of effective defenses, and what orgs can do to prepare for an influx of holiday-infused ransomware targeting.

Researching and Remediating RCEs via GitHub Actions - Bar Kaduri, Roi Nisimi - ASW #355
Application Security Weekly (Audio)
Pull requests are a core part of collaboration, whether in open or closed source. GitHub has documented some of the security consequences of misconfiguring how PRs can trigger actions. But what happens when repo owners don't read the docs? Bar Kaduri and Roi Nisimi walk through their experience in reading docs, finding vulns, demonstrating exploits, and working with repo owners to improve their security. Their work highlights the challenges in maintaining good security guidance, figuring out secure defaults, and how so many orgs still struggle with triaging external security reports --...

Quantum Computing Isn’t A Threat To Blockchains - Yet - Martha Bennett, Sandy Carielli - ASW #354
Application Security Weekly (Audio)
The post quantum encryption migration is going to be a challenge, but how much of a challenge? There are several reasons why it is different from every other protocol and cypher iteration in the past. Is today's hardware up to the task? Is it just swapping out a library, or is there more to it? What is the extent of software, systems, and architecture that have to be updated or replaced to complete the migration? Can we get it all done by 2030? Sandy Carielli and Martha Bennett join us to answer these questions and dive into one area of tech that hasn't been discussed much when it comes to...

Reacting to Ransomware and Setting Secure Defaults - Rob Allen - ASW #353
Application Security Weekly (Audio)
Ransomware attacks typically don't care about memory safety and dependency scanning, they often target old, unpatched vulns and too often they succeed. Rob Allen shares some of the biggest cases he's seen, what they have in common, and what appsec teams could do better to help them. Too much software still requires custom configuration to make it more secure. And too few software makers are embracing secure by default, let alone secure by design. In the news, passively monitoring geosynchronous satellite communications on the cheap, successful LLM poisoning of any size model with a single size...

As genAI becomes a more popular tool in software engineering, the definition of “secure coding” is changing. This session explores how artificial intelligence is reshaping the way developers learn, apply, and scale secure coding practices — and how new risks emerge when machines start generating the code themselves. We’ll dive into the dual challenge of securing both human-written and AI-assisted code, discuss how enterprises can validate AI outputs against existing security standards, and highlight practical steps teams can take to build resilience into the entire development pipeline. Join us as we look ahead to the convergence of secure software engineering and AI security — where trust, transparency, and tooling will define the future of code safety.

Understand the history of threat modeling with Adam Shostack. Learn how threat modeling has evolved with the Four Question Framework and can work in your organizations in the wake of the AI revolution.
Whether you're launching a formal Security Champions program or still figuring out where to start, there's one truth every security leader needs to hear: You already have allies in your org -- they're just waiting to be activated. In this session, we’ll explore how identifying and empowering your internal advocates is the fastest, most sustainable way to drive security culture change. These are your early adopters: the developers, engineers, and team leads who already “get it,” even if their title doesn’t say “security.”
We’ll unpack:
- Why you need help from people outside the security org to actually be effective
- Where to find your natural allies (hint: it starts with listening, not preaching)
- How to support and energize those allies so they influence the majority
- What behavioral science tells us about spreading change across an organization
