Application Security Weekly (audio)

We have a top ten list entry for Insecure Design, pledges to CISA's Secure by Design principles, and tons of CVEs that fall into familiar categories of flaws. But what does it mean to have a secure design and how do we get there? There are plenty of secure practices that orgs should implement are supply chains, authentication, and the SDLC. Those practices address important areas of risk, but only indirectly influence a secure design. We look at tactics from coding styles to design councils as we search for guidance that makes software more secure.

We take advantage of April Fools to look at some of appsec's myths, mistakes, and behaviors that lead to bad practices. It's easy to get trapped in a status quo of chasing CVEs or discussing which direction to shift security. But scrutinizing decimal points in CVSS scores or rearranging tools misses the opportunity for more strategic thinking. We satirize some worst practices in order to have a more serious discussion about a future where more software is based on secure designs.

LLMs are helping devs write code, but is it secure code? How are LLMs helping appsec teams? Keith Hoodlet returns to talk about where he's seen value from genAI, where it fits in with tools like source code analysis and fuzzers, and where its limitations mean we'll be relying on humans for a while. Those limitations don't mean appsec should dismiss LLMs as a tool. It means appsec should understand how things like context windows might limit a tool's security analysis to a few files, leaving a security architecture review to humans.

Just three months into 2025 and we already have several hundred CVEs for XSS and SQL injection. Appsec has known about these vulns since the late 90s. Common defenses have been known since the early 2000s. Jack Cable talks about CISA's Secure by Design principles and how they're trying to refocus businesses on addressing vuln classes and prioritizing software quality -- with security one of those important dimensions of quality.

Curl and libcurl are everywhere. Not only has the project maintained success for almost three decades now, but it's done that while being written in C. Daniel Stenberg talks about the challenges in dealing with appsec, the design philosophies that keep it secure, and fostering a community to create one of the most recognizable open source projects in the world.

Minimizing latency, increasing performance, and reducing compile times are just a part of what makes a development environment better. Throw in useful tests and some useful security tools and you have an even better environment. Dan Moore talks about what motivates some developers to prefer a "local first" approach as we walk through what all of this means for security. Applying forgivable vs. unforgivable criteria to reDoS vulns, what backdoors in LLMs mean for trust in building software, considering some secure AI architectures to minimize prompt injection impact, developer reactions to Rust, and more!

We're getting close to two full decades of celebrating web hacking techniques. James Kettle shares which was his favorite, why the list is important to the web hacking community, and what inspires the kind of research that makes it onto the list. We discuss why we keep seeing eternal flaws like XSS and SQL injection making these lists year after year and how clever research is still finding new attack surfaces in old technologies. But there's a lot of new web technology still to be examined, from HTTP/2 and HTTP/3 to WebAssembly.

Code scanning is one of the oldest appsec practices. In many cases, simple grep patterns and some fancy regular expressions are enough to find many of the obvious software mistakes. Scott Norberg shares his experience with encountering code scanners that didn't find the .NET vuln classes he needed to find and why that led him to creating a scanner from scratch. We talk about some challenges in testing tools, making smart investments in engineering time, and why working with .NET's compiler made his decisions easier. Segment Resources: -https://github.com/ScottNorberg-NCG/CodeSheriff.NET Identifying and eradicating unforgivable vulns, an unforgivable flaw (and a few others) in DeepSeek's iOS app, academics and industry looking to standardize principles and practices for memory safety, and more!

Threat modeling has been in the appsec toolbox for decades. But it hasn't always been used and it hasn't always been useful. Sandy Carielli shares what she's learned from talking to orgs about what's been successful, and what's failed, when they've approached this practice. Akira Brand joins to talk about her direct experience with building threat models with developers. Speculative data flow attacks demonstrated against Apple chips with SLAP and FLOP, the design and implementation choices that led to OCSP's demise, an appsec angle on AI, updating the threat model and recommendations for implementing OAuth 2.0, and more!

A lot of AI security boils down to the boring, but important, software security topics that appsec teams have been dealing with for decades. Niv Braun explains the distinctions between AI-related and AI-specific security as we avoid the FUD and hype of genAI to figure out where appsec teams can invest their time. He notes that data scientists have been working with ML and sensitive data sets for a long time, and it's good to have more scrutiny on what controls should be present to protect that data.

What’s in store for appsec in 2025? Sure, there'll be some XSS and SQL injection, but what about trends that might influence how appsec teams plan? Cody Scott shares five cybersecurity and privacy predictions and we take a deep dive into three of them. We talk about finding value to appsec from AI, why IoT and OT need both programmatic and technical changes, and what the implications of the next XZ Utils attack might be.

There's a pernicious myth that developers don't care about security. In practice, they care about code quality. What developers don't care for is ambiguous requirements. Ixchel Ruiz shares her experience is discussing software designs, the challenges in prioritizing dev efforts, and how to help open source project maintainers with their issue backlog.

All appsec teams need quality tools and all developers benefit from appsec guidance that's focused on meaningful results. Greg Anderson shares his experience in bringing the OWASP DefectDojo project to life and maintaining its value for over a decade. He reminds us that there are tons of appsec teams with low budgets and few members that need tools to help them bring useful insights to developers. Segment Resources: https://owasp.org/www-project-defectdojo/ Three-quarters of CISOs surveyed reported being "overwhelmed" by the growing number of tools and their alerts: https://www.darkreading.com/cloud-security/cisos-throwing-cash-tools-detect-breaches As many as one-fifth of all cybersecurity alerts turn out to be false positives. Among 800 IT professionals surveyed, just under half of them stated that approximately 40% of the alerts they receive are false positives: https://www.securitymagazine.com/articles/97260-one-fifth-of-cybersecurity-alerts-are-false-positives 91% of organizations knowingly released v

Practices around identity and managing credentials have improved greatly since the days of infosec mandating 90-day password rotations. But those improvements didn't arise from a narrow security view. Hannah Sutor talks about the importance of balancing security with usability, the importance of engaging with users when determining defaults, and setting an example for transparency in security disclosures.

Observability is a lot more than just sprinkling printf statements throughout a code base. Adriana Villela explains principles behind logging, traceability, and metrics and how the OpenTelemetry project helps developers gather this useful information. She also provides suggestions on starting logging from scratch, how to avoid information overload, and how engaging users about their experience with solutions like OpenTelemetry makes for better software -- a lesson that appsec teams can apply to paved roads and security guardrails.

This week's interview dives deep into the state of biometrics with two Forrester Research analysts! This discussion compares and contrasts regional approaches to biometrics; examine the security challenges and benefits of their implementation; and reveal how biometrics holds the keys to a range of engagement models of the future. Andras Cser dives into the technical end of things and explains how biometrics can be resilient to attack. We can't replace our fingerprints or faces, but as Andras explains, there's no need to, thanks to how biometrics actually work. Then, Enza takes us through the latest on privacy in biometrics - a concern for both consumers, and businesses tasked with complying with privacy regulations and avoiding costly fines. Finally, get a sneak peek into the upcoming Forrester Security & Risk Summit. Whether you're an industry professional or just curious about the implications of biometrics, this episode delivers insights you won't want to miss! This week, in the Application Security Ne

In this week's interview, Melinda Marks' joins us to discuss her latest research. Her recent report Modernizing Application Security to Scale for Cloud-Native Development delves into many aspects and trends affecting AppSec as it matures, particularly in cloud-first organizations. We also discuss the fuzzy line between "cloud-native" AppSec and everything else that refuses to disappear, particularly for organizations that weren't born cloud-native and still have legacy workloads to worry about. Integrating security into the SDLC and CI/CD pipelines, infrastructure as code (IaC) trends, best of breed vs platform, and other aspects of AppSec get discussed as well! This week, in the Application Security News, we spend a lot of time on some recent vulnerabilities. We take this opportunity to talk about how to determine whether or not a vulnerability is worth a critical response. Can AI fully automate DevSecOps Governance? Adrian has his reservations, but JLK is bullish. Is it bad that 70% of DevSecOps profession

After spending a decade working for appsec vendors, Grant McKracken wanted to give something back. He saw a gap in the market for free or low-cost services for smaller organizations that have real appsec needs, but not a lot of means to pay for it. He founded DarkHorse, who offers VDPs and bug bounties to organizations of all sizes for free, or for as low of cost as possible. While not a non-profit, the company's goal is to make these services as cheap as possible to increase accessibility for smaller or more budget-constrained organizations. The company has also introduced the concept of "fractional pentesting", access to cyber talent when and how you need it, based on what you can afford. This implies services beyond just offensive security, something we'll dive deeper into in the interview. We don't see DarkHorse ever competing with the larger Bug Bounty platforms, but rather providing services to the organizations too small for the larger platforms to sell to.
