Tackling complexity at the heart of data. With Domain-Driven Data Modeling (DDDM) the main principles are: - focus on your core ("domain and sub-domains") - break down complex problems into smaller ones ("bounded context") - use data modeling as a communication tool ("ubiquitous language") - keep together what belongs together ("aggregates") - reach a shared understanding between business and tech ("collaboration of domain experts and developers") - iterate and evolve ("continuous refinement")

Data modeling for relational databases is performed according to the rules of normalization, so larger tables are divided into smaller ones linked together with relationships. The purpose is to eliminate redundant or duplicate data. But NoSQL databases are completely different. They require a mindshift in schema design in order to leverage their capabilities, as well as a data modeling tool built specially for this new breed of state-of-the art technology.

Co-locate data models and their schema artifacts with application code, so they can follow the lifecycle of application changes. Provides a single source-of-truth for business and technical stakeholders as the data model in the Git repo is the source of the technical schemas used by applications, databases, and APIs at the same time as it is the source for the business-facing data dictionaries. This architecture contributes to the shared understanding of the context and meaning of data by all the stakeholders.

Tutorial Workgroup - Working with Forks

PascalDesmarets1

With the fork & pull strategy, contributors create their own (remote) copy of the original repository and push changes to that copy, which is referred to as a fork. Once a contribution is ready, it can be submitted through a pull request: the contributor basically requests the maintainer(s) of the original repository to pull into that repository the work that has been prepared in a fork. Note that nothing prevents multiple contributors from working together in the same fork prior to submitting their changes to the original repository. The main advantage of the fork & pull strategy is that the contributors do not need to be explicitly granted push access rights to the original repository. That's why that strategy is typically used for large-scale open source projects where most contributors are not known by the maintainers of the repository. Another advantage of the fork & pull strategy is that it prevents the original repository from being polluted with branches that are created and then abandoned but never deleted by their author.

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. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

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.
