The principal benefit this book is to provide a holistic and comprehensible view of the entire software development process, including ongoing evolution and support. It treats development as a collaborative effort with triad communication between a tester, a programmer, and a representative from the user community or a Subject Matter Expert (SME).  Progress is measured by user acceptance in each cycle before proceeding to the next step of an activity. There is no test stage in the DPAC model: continuous testing is represented in the backswing (Check Phase) of each activity cycle.    This approach posits that there exists some "e;happy path"e; that represents the intent of the project as declared by the objectives of a Vision Statement, and that this path can be revealed by an iterative and incremental process of "e;freeing the statue from the stone."e;  As the image of this path unfolds, more waste is removed while retaining conceptual integrity.  The example presented herein walks the reader through an application of the model.  This book should be of great interest to Product and Project Managers new to the concept of a lean agile development effort, and all practitioners of an agile methodology or those considering or just beginning an agile journey.What You'll LearnSee how the various disciplines constituting the software development process come togetherUnderstand where in the development process management, you can exercise measurement of progress and controlReview how a quality engineering program will positively affect the quality of the development processExamine how the quality of the development process profoundly affects the quality of the software systemWho This Book Is ForManagers, from the C-Suite (CEO,CXO, CIO) to line managers including project managers, and practitioners including programmers, testers, and mid-level managers (Technical Project Managers, Software Quality Engineers, and Coaches).

Cyberattacks continue to increase in volume and sophistication, targeting everything owned, managed, and serviced from the cloud. Today, there is widespread consensus-it is not a matter of if, but rather when an organization will be breached. Threat actors typically target the path of least resistance. With the accelerating adoption of cloud technologies and remote work, the path of least resistance is shifting in substantive ways. In recent years, attackers have realigned their efforts, focusing on remaining undetected, monetization after exploitation, and publicly shaming organizations after a breach.New, innovative, and useful products continue to emerge and offer some cloud protection, but they also have distinct limitations. No single, standalone solution or strategy can effectively protect against all cloud attack vectors or identify all malicious activity. The simple fact is that the cloud is based on a company's assets being offered as services. As a result, the best security any organization can achieve is to establish controls and procedures in conjunction with services that are licensed in the cloud.Cloud Attack Vectors details the risks associated with cloud deployments, the techniques threat actors leverage, the empirically-tested defensive measures organizations should adopt, and shows how to improve detection of malicious activity.What You'll LearnKnow the key definitions pertaining to cloud technologies, threats, and cybersecurity solutionsUnderstand how entitlements, permissions, rights, identities, accounts, credentials, and exploits can be leveraged to breach a cloud environmentImplement defensive and monitoring strategies to mitigate cloud threats, including those unique to cloud and hybrid cloud environmentsDevelop a comprehensive model for documenting risk, compliance, and reporting based on your cloud implementation Who This Book Is ForNew security professionals, entry-level cloud security engineers, managers embarking on digital transformation, and auditors looking to understand security and compliance risks associated with the cloud
