Application Layer Protocols for the IoT
A 5-part course on the two most popular application layer protocols for the IoT namely MQTT and CoAP.
Http Introduction
HTTP is the most popular application protocol on the internet. It uses the client-server model where an HTTP client sends a request to an HTTP server using a request method like GET or POST. The server then returns a response with a status code and can include a message body. A URL identifies a web resource and includes the protocol, hostname, port, and path. HTTP specifications are maintained by the W3C and the current versions are HTTP/1.0 and HTTP/1.1. The HTTP request and response include a start line, headers, and optional body. Common status codes indicate success, redirection, or client/server errors.

QUIC protocol.pptx
The QUIC protocol was developed by Google to improve performance over TCP for web applications by reducing latency. QUIC sits on top of UDP rather than TCP, allowing it to establish an encrypted connection in one round trip rather than the multiple round trips required by TCP. This reduces latency compared to HTTPS which uses TCP. QUIC also allows for multiplexed streams that can continue independently if one stream experiences packet loss, avoiding the head-of-line blocking that can occur with TCP connections. Major uses of QUIC include web browsing, video streaming, cloud services, and gaming.

Congestion avoidance in TCP
Congestion avoidance mechanisms aim to predict impending congestion and reduce data transmission rates before packet loss occurs. Three main methods are DEC bit, Random Early Detection (RED), and source-based approaches. DEC bit uses routers to explicitly notify sources of congestion. RED drops packets probabilistically based on average queue length to implicitly notify sources. Source-based methods monitor round-trip times and window sizes to detect congestion and adjust transmission rates accordingly.
Client server chat application
This document summarizes a client-server chat application. It discusses networking basics like TCP, ports, and sockets. TCP ensures data is received in the same order sent using acknowledgements. Ports identify services/processes, and sockets connect two programs. The server runs each client on a separate thread. The client requests a connection to the server at a given port/IP. Classes like Swing, IO, and Net are used. Potential uses include private LAN chat, file transfer, broadcasting notices, and serving as a backup connection.

Originally presented at CF Summit Europe 2017 in Basel, Switzerland. The abstract of the talk was:
The Bluemix UI (which runs on CloudFoundry) is the front-end to Bluemix, IBM’s open cloud hosting platform. The original implementation as a single-page, monolithic Java web app brought with it many demons, such as poor performance, lack of scalability, inability to push small updates, and difficulty for other teams to contribute code. Over the last 2 years, the team has been on a mission to slay these demons by embracing cloud native principles and splitting the monolith into smaller Node.js microservices. The effort to migrate to a more modern and scalable architecture has paid large dividends, but has also left behind a few battle scars from wrestling with the added complexity cloud native can bring. The team had to tackle problems in a wide variety of areas, including: large-scale deployments, continuous integration, monitoring, problem determination, high availability, and security. Tony Erwin will discuss the advantages of microservice architectures, ways that Node.js has increased developer productivity, approaches to phasing microservices into a live product, and real-life lessons learned in the deployment and management of Node.js microservices across multiple CloudFoundry environments. His war stories will prepare you to wage your own battles against monoliths everywhere -- happy slaying!

How to grow your own Microservice?
The document discusses how to grow microservices from a monolithic architecture using a staged approach. It recommends starting with a modular monolith broken into bounded context modules that can be deployed and tested independently. These modules can then be upgraded to independent microservices by separating databases, exposing APIs, and moving to an eventual consistency model. The process should be iterative, allowing code to be refactored and services extracted gradually based on factors like scalability needs and usage patterns. Practical advice includes API-first design, avoiding reusable frameworks, using schema per bounded context, and embracing testing and devops best practices.
Microservices in Azure

Removing Uninteresting Bytes in Software Fuzzing
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.

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).

Climate Impact of Software Testing at Nordic Testing Days
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.
