Trusting machines with robust, unbiased and reproducible AI Margriet Groenendijk
To trust a decision made by an algorithm, we need to know that it is reliable and fair, that it can be accounted for, and that it will cause no harm. We need assurance that it cannot be tampered with and that the system itself is secure. We need to understand the rationale behind the algorithmic assessment, recommendation or outcome, and be able to interact with it, probe it – even ask questions. And we need assurance that the values and norms of our societies are also reflected in those outcomes.
Learn about how bias can take root in machine learning algorithms and ways to overcome it.

Securing the Web without site-specific passwordsFrancois Marier
Has anyone else noticed that the OWASP Top 10 is not changing very much? Especially in the realm of authentication-related problems. I don't claim to have the one true solution for this, but one thing is certain: if we change how things are done on the web and relieve developers from having to store passwords, we can make things better.
We need to let web developers outsource their authentication needs to people who can do it well. Does that mean we should force all of our users to join Facebook? Well not really. That might work for some sites, but outsourcing all of our logins to a single for-profit company isn't a solution that works for the whole web.
The open web needs a better solution. One that enable users to choose their identity provider and shop for the most secure one if that's what they're into. This is the promise behind Persona and the BrowserID protocol. Choose your email provider carefully and let's get rid of all of these site-specific passwords that are just sitting there waiting to be leaked and cracked.

php[tek] 2018 - Biometrics, fantastic failure point of the futureAdam Englander
This presentation attempts to prepare developers for the coming storm of biometric authentication. It is coming; for many, it is already here. Unfortunately, few of us have been prepared to select tools for utilizing biometric authentication properly. In this presentation, Adam Englander will express the special dangers of biometrics with regards to lifespan and storage. Due to the user's inability to change a biomteric, it is much more valuable to bad actors as the lifespan will undoubtedly exceed the lifespan of the cryptography. Any biometric database stolen today will likely be able to be cracked by the average computer in 20 years. This creates a unique problem many of us have not had to tackle before. We need a different mindset when thinking about biometrics. This presentation will try and give that much-needed perspective.

With the dominance of Mobile Apps, Single Page Apps for the Web, and Micro-Services, we are all building more APIs than ever before. Like many other developers, I had struggled with finding the right mix of security and simplicity for securing APIs. Some standards from the IETF have made it possible to accomplish both. Let me show you how to utilize existing libraries to lock down you API without writing a ton of code.
In this tutorial, you will learn how to write a secure API with future proof security utilizing JOSE. JOSE is a collection of complimentary standards: JWT, JWE, JWS, JWA, and JWK. JOSE is used by OAuth, OpenID, and others to secure communications between APIs and consumers. Now you can use it to secure your API.
Cryptography is the invisible layer protecting everything around us. As software engineers, we are required to have some understanding of cryptography. Most of us only have a cursory understanding.

php[tek] 2108 - Cryptography Advances in PHP 7.2Adam Englander
There were some pretty substantial cryptography advances in PHP 7.2. Most of these changes were made to make advanced cryptography easier to use. That’s a good thing for developers and end users alike. The addition of libsodium is a game changer. It makes synchronous and asynchronous cryptography a no-brainer and adds better hashing than we've ever had. Argon2i for passwords is pretty substantial as well. We’ll go over the changes and have some practical examples of each. Developers need to know about these advances and just how awesome they are.
Biometric identification might be more secure than passwords, but it’s still vulnerable to hacking. Why not hold up a photograph of the phone owner to fool the new facial recognition system? In this presentation, Adam Englander will walk through the risks and dangers of leveraging biometrics for user authentication, and why we all should be thinking twice about it.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

English Message Patterns
• Spaces can be determined based on predictable word patterns
• Single letter words will be either the letter i or a
• In a two letter word, one of the letters is a vowel
• Three letter words mostly start and end with consonants and nearly
always have a vowel in the middle
• The letter e is the most common of all letters
