Do you find it difficult to understand how popular companies like WhatsApp and Amazon find valuable insights from large amounts of unorganized data? The Unsupervised Learning Workshop will give you the confidence to deal with cluttered and unlabeled datasets, using unsupervised algorithms in an easy and interactive manner.The book starts by introducing the most popular clustering algorithms of unsupervised learning. You'll find out how hierarchical clustering differs from k-means, along with understanding how to apply DBSCAN to highly complex and noisy data. Moving ahead, you'll use autoencoders for efficient data encoding.As you progress, you’ll use t-SNE models to extract high-dimensional information into a lower dimension for better visualization, in addition to working with topic modeling for implementing natural language processing (NLP). In later chapters, you’ll find key relationships between customers and businesses using Market Basket Analysis, before going on to use Hotspot Analysis for estimating the population density of an area.By the end of this book, you’ll be equipped with the skills you need to apply unsupervised algorithms on cluttered datasets to find useful patterns and insights.

Vulnerability researchers are in increasingly high demand as the number of security incidents related to crime continues to rise with the adoption and use of technology. To begin your journey of becoming a security researcher, you need more than just the technical skills to find vulnerabilities; you’ll need to learn how to adopt research strategies and navigate the complex and frustrating process of sharing your findings. This book provides an easy-to-follow approach that will help you understand the process of discovering, disclosing, and publishing your first zero-day vulnerability through a collection of examples and an in-depth review of the process.You’ll begin by learning the fundamentals of vulnerabilities, exploits, and what makes something a zero-day vulnerability. Then, you'll take a deep dive into the details of planning winning research strategies, navigating the complexities of vulnerability disclosure, and publishing your research with sometimes-less-than-receptive vendors.By the end of the book, you'll be well versed in how researchers discover, disclose, and publish vulnerabilities, navigate complex vendor relationships, receive credit for their work, and ultimately protect users from exploitation. With this knowledge, you’ll be prepared to conduct your own research and publish vulnerabilities.

Threat Hunting with Elastic Stack will show you how to make the best use of Elastic Security to provide optimal protection against cyber threats. With this book, security practitioners working with Kibana will be able to put their knowledge to work and detect malicious adversary activity within their contested network.You'll take a hands-on approach to learning the implementation and methodologies that will have you up and running in no time. Starting with the foundational parts of the Elastic Stack, you'll explore analytical models and how they support security response and finally leverage Elastic technology to perform defensive cyber operations.You’ll then cover threat intelligence analytical models, threat hunting concepts and methodologies, and how to leverage them in cyber operations. After you’ve mastered the basics, you’ll apply the knowledge you've gained to build and configure your own Elastic Stack, upload data, and explore that data directly as well as by using the built-in tools in the Kibana app to hunt for nefarious activities.By the end of this book, you'll be able to build an Elastic Stack for self-training or to monitor your own network and/or assets and use Kibana to monitor and hunt for adversaries within your network.
Threat Modeling Best Practices. Proven frameworks and practical techniques to secure modern systems
Derek Fisher
Threat modeling has become a cornerstone of modern cybersecurity, yet it is often overlooked, leaving security gaps that attackers can exploit. With the rise in system complexity, cloud adoption, AI-driven threats, and stricter compliance requirements, security teams need a structured approach to proactively spot and stop risks before attackers do. This book delivers exactly that, offering actionable insights for applying industry best practices and emerging technologies to secure systems. It breaks down the fundamentals of threat modeling and walks you through key frameworks and tools such as STRIDE, MITRE ATT&CK, PyTM, and Attack Paths, helping you choose the right model and create a roadmap tailored to your business. You'll learn how to use leading threat modeling tools, identify and prioritize potential threats, and integrate these practices into the software development life cycle to detect risks early. The book also examines how AI can enhance analysis and streamline security decision-making for faster, stronger defenses.By the end, you'll have everything you need to build systems that anticipate and withstand evolving threats, keeping your organization secure in an ever-changing digital landscape.*Email sign-up and proof of purchase required
Threat Modeling Gameplay with EoP. A reference manual for spotting threats in software architecture
Brett Crawley, Adam Shostack
Are you looking to navigate security risks, but want to make your learning experience fun? Here's a comprehensive guide that introduces the concept of play to protect, helping you discover the threats that could affect your software design via gameplay.Each chapter in this book covers a suit in the Elevation of Privilege (EoP) card deck (a threat category), providing example threats, references, and suggested mitigations for each card. You’ll explore the methodology for threat modeling—Spoofing, Tampering, Repudiation, Information Disclosure, and Elevation of Privilege (S.T.R.I.D.E.) with Privacy deck and the T.R.I.M. extension pack. T.R.I.M. is a framework for privacy that stands for Transfer, Retention/Removal, Inference, and Minimization. Throughout the book, you’ll learn the meanings of these terms and how they should be applied. From spotting vulnerabilities to implementing practical solutions, the chapters provide actionable strategies for fortifying the security of software systems.By the end of this book, you will be able to recognize threats, understand privacy regulations, access references for further exploration, and get familiarized with techniques to protect against these threats and minimize risks.

With resources on Android and Kotlin abound, it’s difficult to find content that focuses on resolving common challenges faced by app developers. This book by Gema Socorro Rodríguez – a Google Developer Expert for Android with over 15 years of experience and a proven track record as an effective instructor – is designed to bridge the gap between theory and real-world application. It equips you with the skills to tackle everyday problems in Android development through hands-on projects.Under Gema's expert guidance, you’ll build three sophisticated Android projects. You'll start your development journey by building a WhatsApp-like application, learning how to process asynchronous messages reactively, render them using Jetpack Compose, and advance to creating and uploading a backup of these messages. Next, you’ll channel your creativity into Packtagram, an Instagram-inspired app that offers advanced photo-editing capabilities using the latest CameraX libraries. Your final project will be a Netflix-style app, integrating video playback functionality with ExoPlayer for both foreground and background operations, and implementing device casting features.By the end of this book, you'll have crafted three fully functional, multi-platform projects and gained the confidence to solve the most common challenges in Android development.
