FSI300 Bringing the Brains Behind Alexa to Financial Services

Amazon Web Services

The pressure to implement digital strategies is being felt by all Financial Services organizations. Part of this pressure comes from today’s emphasis on customers and their elevated expectations around omni-channel experiences. AWS has been working with numerous Financial Services enterprises to create chatbots (that run across multiple platforms and channels) to service both employees and customers through speech and text conversational interfaces. In this session, we will be walk through how to create a chatbot solution powered by AWS Artificial Intelligence, Machine Learning, and Alexa-related services. Built for the unique issues of Financial Services organizations, this solution can respond to customer service requests (such as balances, fund transfers, and account information changes) and make employee tasks easier (such as portfolio management, client information access, and transaction initiation). AWS services enabled include Lex, Polly, DynamoDB, S3, the MobileHub, and AWS SDK.

Building AI-powered Serverless Applications on AWS

Adrian Hornsby

Slides from my talk at the AWSLoft in London https://awsloft.london/session/2017/a5da881d-67f8-4af5-8ace-4f8adcf579db "In this talk, we will show the audience how to build and deploy serverless AI-powered applications on AWS. In particular, two demos will be analysed in depths. The first demo is a simple mobile web app that allows a user to upload or take a picture with their mobile phone. The result is then spoken out loud using Amazon Polly. This demo is deployed using the AWS CLI (command line interface) with scripting techniques. The second demo is a podcast generator which connects to any RSS feed and converts that feed into a podcast. The result can then be played on iTunes or any podcast player. This demo uses AWS Lambda and Amazon Polly and is deployed using the Serverless framework. We will go through the architecture, the APIs, the code itself and the deployment of those two applications using Amazon Rekognition, Amazon Polly, AWS Lambda, Amazon S3, Amazon Route53, Elasticsearch, and more."

Grown-up javascript with AngularJS

Mykhailo Kotsur

Surprisingly many web developers don't realize that Javascript ecosystem is not the same as it was few years ago, when building a single-page web application was considered risky business. Those times are way behind. Modern javascript MVC frameworks are if not silver, but certainly solid bullets which every person who wants to use benefits of evolution should be aware of. I'll tell you about challenges that happen when you build a single-page application, about REST interface, and certainly about one of such frameworks: AngularJS, created by hackers from Google keeping in mind best software development principles such as TDD and dependency injections. That's why writing with AngularJS is such a pleasure.

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software Fuzzing

Aftab 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. - These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.

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). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations.
