Companies deploy tools (usually lots of tools) to address different threats to supply chain security. Melinda Marks shares some of the chaos those companies still face when trying to prioritize investments, measure risk, and scale their solutions to keep pace with their development. Not only are companies still figuring out supply chain, but now they're bracing for the coming of genAI and how that will just further highlight the current struggles they're having with data security and data privacy.

How can open source projects find a funding model that works for them? What are the implications with different sources of funding? Simon Bennetts talks about his stewardship of Zed Attack Proxy and its journey from OWASP to OpenSSF to an Open Source Fellowship with Crash Override. Mark Curphy adds how his experience with OWASP and the appsec community motivated him to create Crash Override and help projects like ZAP gain the support they deserve.

There are as many paths into infosec as there are disciplines within infosec to specialize in. Karan Dwivedi talks about the recent book he and co-author Raaghav Srinivasan wrote about security engineering. There's an appealing future to security taking on engineering roles and creating solutions to problems that orgs face. We talk about the breadth and depth of security engineering and ways to build the skills that will help you in your appsec career.

We look into the supply chain saga of the XZ Utils backdoor. It's a wild story of a carefully planned long con to add malicious code to a commonly used package that many SSH connections rely on. It hits themes from social engineering and abuse of trust to obscuring the changes and suppressing warnings. It also has a few lessons about software development, the social and economic dynamics of open source, and strategies for patching software.

It's an exciting topic partially because so much other appsec is boring. And that boring stuff is important to get right first. We also talk about what parts of this that orgs should be worried about and what types of threats they should be prioritizing instead.

Sometimes infosec problems can be summarized succinctly, like "patching is hard". Sometimes a succinct summary sounds convincing, but is based on old data, irrelevant data, or made up data. Adrian Sanabria walks through some of the archeological work he's done to dig up the source of some myths. We talk about some of our favorite (as in most disliked) myths to point out how oversimplified slogans and oversimplified threat models lead to bad advice -- and why bad advice can make users less secure.

One of the biggest failures in appsec is an attitude that blames users for security problems. A lot of processes and workflows break down because of an insecure design or insecure defaults. Benedek Gagyi chats with us about the impact of the user experience (UX) on security and why it's not only important to understand how to make a user's life easier, but in defining who that user is in the first place.

Lots of companies need cybersecurity programs, as do non-profits. Tyler Von Moll talks about how to get small organizations started on security and how to prioritize initial investments. While an appsec program likely isn't going to be one of the first steps, it's going to be an early one. What decisions can you make at the start that will benefit the program in the years that follow? What does an appsec program look like at a small scale?

A majority of internet traffic now originates from APIs, and cybercriminals are taking advantage. Increasingly, APIs are used as a common attack vector because they’re a direct pathway to access sensitive data. In this discussion, Lebin Cheng shares what API attack trends Imperva, a Thales Company has observed over the past year, and what steps organizations can take to protect their APIs.

The need for vuln management programs has been around since the first bugs -- but lots of programs remain stuck in the past. We talk about the traps to avoid in VM programs, the easy-to-say yet hard-to-do foundations that VM programs need, and smarter ways to approach vulns based in modern app development. We also explore the ecosystem of acronyms around vulns and figure out what's useful (if anything) in CVSS, SSVC, EPSS, and more.

Farshad Abasi joins us again to talk about creating a new OWASP project, the Secure Pipeline Verification Standard. (Bonus points for not being a top ten list!) We talk about what it takes to pitch a new project and the problems that this new project is trying to solve. For this kind of project to be successful -- as in making a positive impact to how software is built -- it's important to not only identify the right audience, but craft guidance in a way that's understandable and achievable for that audience. This is also a chance to learn more about a project in its early days and the opportunities for participating in its development!

Check out this interview from the ASW Vault, hand picked by main host Mike Shema! This segment was originally published on Dec 13, 2022.

Threat modeling is an important part of a security program, but as companies grow you will choose which features you want to threat model or become a bottleneck. What if I told you, you can have your cake and eat it too. It is possible to scale your program and deliver higher quality threat models.
