Developing IoT with Zephyr is a journey from hardware all the way to application. It involves multiple teams and expertise, from hardware to cloud and application development. This talk will cover the options for getting a Zephyr app connected (WiFi, Ethernet, Cellular), selecting the right data encoding (JSON/CBOR), securing the data transfer (DTLS/TLS), and choosing a protocol (HTTP/MQTT/COAP). But that’s not the end of the story, the cloud needs to manage devices allowed to connect, consume the data being received, open up options for using that data, and be aware of the continued state of the hardware. And once you have the data you need to build a user-facing application on top of it. Understanding this lifecycle will help us as developers to make good choices on what Zephyr provides, helping ensure successful IoT projects.

Pete Warden, Staff Research Engineer and TensorFlow Lite development lead at Google, presents the "Using TensorFlow Lite to Deploy Deep Learning on Cortex-M Microcontrollers" tutorial at the May 2019 Embedded Vision Summit.
Is it possible to deploy deep learning models on low-cost, low-power microcontrollers? While it may be surprising, the answer is a definite “yes”! In this talk, Warden explains how the new TensorFlow Lite framework enables creating very lightweight DNN implementations suitable for execution on microcontrollers. He illustrates how this works using an example of a 20 Kbyte DNN model that performs speech wake word detection, and discusses how this generalizes to image-based use cases. Warden introduces TensorFlow Lite, and explores the key steps in implementing lightweight DNNs, including model design, data gathering, hardware platform choice, software implementation and optimization.

Part 01 Linux Kernel Compilation (Ubuntu)Tushar B Kute
Presentation on "Linux Kernel Compilation" (Ubuntu based).
Presented at Army Institute of Technology, Pune for FDP on "Basics of Linux Kernel Programming". by Tushar B Kute (http://tusharkute.com).
The first version of eBPF hardware offload was merged into the Linux kernel in October 2016 and became part of Linux v4.9. For the last two years the project has been growing and evolving to integrate more closely with the core kernel infrastructure and enable more advanced use cases. This talk will explain the internals of the kernel architecture of the offload and how it allows seamless execution of unmodified eBPF datapaths in HW.
File system is an approach on how the data can be
organized in order to have a meaningful read or write in a
system. File systems provides a very easy way of identifying data like where it begins and ends. The group of such data can be called as “Files”. The method used to manage these groups of data can be called as “File systems”
The Network File System (NFS) Version 4 is a distributed file system similar to previous versions of NFS in its straightforward design, simplified error recovery, and independence of transport protocols and operating systems for file access in a heterogeneous network.
NFS, was developed by Sun Microsystems to provide distributed transparent file access in a heterogeneous network. It achieves this by being relatively simple in design and not relying too heavily on any particular file system model.
This presentation is based on the paper of “The NFS Version 4 Protocol” written by Brian Pawlowski, Spencer Shepler, Carl Beame, Brent Callaghan, Michael Eisler, David Noveck, David Robinson and Robert Thurlow.
This talk provides an overview of the Xen Project eco-system and its main use-cases in a number of important market segments: it covers server virtualization, cloud computing and embedded, automotive and related. Lars Kurth highlights why the Xen Project is relevant in these market segments: he provides an overview of the Xen Project's architecture, relevant existing functionality and ongoing and planned developments. To complement the picture, he covers open-source projects that are related to Xen and are of interest for these use-cases. Excellent Software security is key to all of these use-cases. Thus, Lars specifically covers the Xen Project's security features, track record and touches on the project's security practices. He concludes with a few resources that help you get started with the Xen Project and highlight Internship Programs which the project supports.

Azure 101: Shared responsibility in the Azure CloudPaulo Renato
Whether you’re working exclusively on Azure or with multiple cloud environments, there are certain things you should consider when moving assets to the public cloud. As with any cloud deployment, security is a top priority, and moving your workloads to the Azure cloud doesn’t mean you’re not responsible for the security of your operating system, applications, and data.
Building on the security of the Azure infrastructure, this shared security responsibility starts with making sure your environment is secure. In this session, we will discuss step-by-step what you need to do to secure access at the administrative, application and network layers.
Asset owners today want to understand how investments made in people, process, or technology are progressing the maturity of their ICS security programs to validate those investments. Whether asset owners are spending one dollar, one million dollars, or one hour of their time, understanding which investments are actually improving the overall ICS security posture and reducing risk is essential to determine where to spend valuable (and sometimes limited) resources.
The NIST Cybersecurity Framework helps asset owners measure security control maturity in both IT and OT domains, and can be useful to help understand whether certain ICS security investments are working or not. This talk will break down all five NIST CSF functions and dive into specific forward thinking use cases used to help jumpstart many of Forescout's industry leading customers.

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).
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.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

IPv6 Fnet code, one, CVE-2020-17467, affects
Link-local Multicast Name Resolution LLMNR), and
2, CVE-2020-24383, and CVE-2020-17470 affect
DNS functionality.
- None of the affected code has been used in the
Zephyr project, while 1.14 does use the Fnet TCP,
it does not use the affected IPv6, DNS or LLMNR
code.
