This book provides an overview of software security analysis in a DevOps cycle including requirements formalisation, verification and continuous monitoring. It presents an overview of the latest techniques and tools that help engineers and developers verify the security requirements of large-scale industrial systems and explains novel methods that enable a faster feedback loop for verifying security-related activities, which rely on techniques such as automated testing, model checking, static analysis, runtime monitoring, and formal methods. The book consists of three parts, each covering a different aspect of security engineering in the DevOps context. The first part,'Security Requirements', explains how to specify and analyse security issues in a formal way. The second part,'Prevention at Development Time', offers a practical and industrial perspective on how to design, develop and verify secure applications. The third part,'Protection at Operations', eventually introduces tools for continuous monitoring of security events and incidents. Overall, it covers several advanced topics related to security verification, such as optimizing security verification activities, automatically creating verifiable specifications from security requirements and vulnerabilities, and using these security specifications to verify security properties against design specifications and generate artifacts such as tests or monitors that can be used later in the DevOps process. The book aims at computer engineers in general and does not require specific knowledge. In particular, it is intended for software architects, developers, testers, security professionals, and tool providers, who want to define, build, test, and verify secure applications, Web services, and industrial systems.

Why software isn't perfect, as seen through the stories of software developers at a run-of-the-mill tech companyContrary to much of the popular discourse, not all technology is seamless and awesome; some of it is simply “good enough.” In Middle Tech, Paula Bialski offers an ethnographic study of software developers at a non-flashy, non-start-up corporate tech company. Their stories reveal why software isn't perfect and how developers communicate, care, and compromise to make software work—or at least work until the next update. Exploring the culture of good enoughness at a technology firm she calls “MiddleTech,” Bialski shows how doing good-enough work is a collectively negotiated resistance to the organizational ideology found in corporate software settings.The truth, Bialski reminds us, is that technology breaks due to human-related issues: staff cutbacks cause media platforms to crash, in-car GPS systems cause catastrophic incidents, and chatbots can be weird. Developers must often labor to patch and repair legacy systems rather than dream up killer apps. Bialski presents a less sensationalist, more empirical portrait of technology work than the frequently told Silicon Valley narratives of disruption and innovation. She finds that software engineers at MiddleTech regard technology as an ephemeral object that only needs to be good enough to function until its next iteration. As a result, they don't feel much pressure to make it perfect. Through the deeply personal stories of people and their practices at MiddleTech, Bialski traces the ways that workers create and sustain a complex culture of good enoughness.

Software is everywhere, but despite being so common and useful, it remains magical and mysterious to many. Still, more and more people are finding themselves working for tech companies, or with an array of software products, services, and tools. This can segregate those who understand tech from those that don't. But it doesn't have to be this way.This book aims to bring these two worlds closer together, allowing people to learn basic concepts of software development in a casual and straight-forward way. Assuming no previous technical knowledge, you'll embark on a journey where you can understand and build a new software project from scratch until it is an advanced product with multiple users. A Friendly Guide to Software Development makes technical concepts broadly available and easy to understand. Imagine moving from a “traditional” company and suddenly finding yourself in one where software is the main product or is a foundational component to it. One is often left to wade through the infinite concepts while still doing their actual jobs. This book closes that gap. In doing so, you'll be able to achieve better communication, which will undoubtedly lead to better working relationships, a better working environment, and ultimately better software.What You'll LearnSee how a new software project is createdExamine the basics of software development and architectureKnow which questions to ask to avoid potential problems and pitfallsStart using and building software projectsWho This Book Is ForThose without a traditional technical background people like business and project managers who need to work closely with software developers and teamsPeople who are interested in building a software system but don't know where to start.Programmers who want to jump to development but have no experience in the industry and its common concepts

This book guides the reader through a design process that was tested and optimized in companies and design bureaus. It not only smoothly integrates modern product development techniques, but also addresses, for each phase, issues related to the management of intangible assets.

Use continuous Integration (CI) and continuous delivery (CD) to improve the speed of software delivery. This book presents a game changer—how to use pipelines to automate the software delivery process. The theories about CI/CD are much the same, but the book covers what the development of pipelines looks like and how testing of pipelines themselves should be performed.Most teams just plunge into coding, without thinking about the CI/CD process itself. Why don't we use the same development method for pipelines that we use for apps? Pipelines code development undergoes similar stages as application code development, such as requirements analysis, development, testing, implementation, operations, and monitoring. This is the starting point of the book. It describes the current challenges with pipeline development and how this process can be improved and structured. It describes in detail how to design pipelines and shows examples in BPMN 2.0 notation. What You'll Learn Know the shortcomings and challenges of current pipeline development such as misalignment between the pipeline engineer and the team's workflow, the use of infrastructure as code (IaC), and pipeline securityUnderstand the need for CI/CD requirements through the book's non-exhaustive list of more than 60 CI/CD requirements provided to inspire and increase awarenessSee how certain choices affect the way a pipeline is designed (and realized)Become familiar with branching strategy, build strategy, test strategy, release strategy, and deployment strategy that are explained in detail in the book, including their effect on pipeline designKnow how pipelines can be unit tested, using a real-world exampleKnow how performance bottlenecks in a pipeline occur, how they can be detected, and how they can be solvedView a complete implementation, including code, showing how the guidelines in this book are applied to a real use case Who This Book Is For DevOps engineers and solution architects involved with automating the software supply chain and using application lifecycle management (ALM)/integration platforms such as Jenkins, CircleCI, Bamboo, and Azure DevOps; intermediate and experienced DevOps engineers (developers, ops engineers, test engineers); and ICT managers interested in the CI/CD pipeline development domain
