Expert Oracle and Java Security
Expert Oracle and Java Security: Programming Secure Oracle Database Applications with Java provides resources that every Java and Oracle database application programmer needs to ensure that they have guarded the security of the data and identities entrusted to them. You'll learn to consider potential vulnerabilities, and to apply best practices in secure Java and PL/SQL coding. Author David Coffin shows how to develop code to encrypt data in transit and at rest, to accomplish single sign-on with Oracle proxy connections, to generate and distribute two-factor authentication tokens from the Oracle server using pagers, cell phones (SMS), and e-mail, and to securely store and distribute Oracle application passwords.Early chapters lay the foundation for effective security in an Oracle/Java environment. Each of the later chapters brings example code to a point where it may be applied as-is to address application security issues. Templates for applications are also provided to help you bring colleagues up to the same secure application standards. If you are less familiar with either Java or Oracle PL/SQL, you will not be left behind; all the concepts in this book are introduced as to a novice and addressed as to an expert.Helps you protect against data loss, identity theft, SQL injection, and address spoofing Provides techniques for encryption on network and disk, code obfuscation and wrap, database hardening, single sign-on and two-factor Provides what database administrators need to know about secure password distribution, Java secure programming, Java stored procedures, secure application roles in Oracle, logon triggers, database design, various connection pooling schemes, and much more

Java Microservices and Containers in the Cloud
Spring Boot helps developers create applications that simply run. When minimal configuration is required to start up an application, even novice Java developers are ready to start. But this simplicity shouldn't constrain developers in addressing more complex enterprise requirements where microservice architecture is concerned. With the need to rapidly deploy, patch, or scale applications, containers provide solutions which can accelerate development, testing as well as production cycles. The cloud helps companies to scale and adapt at speed, accelerate innovation and drive business agility, without heavy upfront IT investment. What if we can equip even a novice developer with all that is required to help enterprises achieve all of this, this book does this and more.Java Microservices and Containers in the Cloud offers a comprehensive guide to both architecture and programming aspects to Java microservices development, providing a fully hands-on experience. We not only describe various architecture patterns but also provide practical implementations of each pattern through code examples. Despite the focus on architecture, this book is designed to be accessible to novice developers with only basic programming skills, such as writing a "Hello World" program and using Maven to compile and run Java code. It ensures that even such readers can easily comprehend, deploy, and execute the code samples provided in the book. Regardless of your current knowledge or lack thereof in Docker, Kubernetes, and Cloud technologies, this book will empower you to develop programming skills in these areas.There is no restriction on beginners attempting to understand serious and non-trivial architecture constraints. While mastering concurrency and scalability techniques often requires years of experience, this book promises to empower you to write microservices, as well as how to containerize and deploy them in the cloud. If you are a non-programming manager who is not afraid to read code snippets, this book will empower you to navigate the challenges posed by seasoned architects. It will equip you with the necessary understanding of specialized jargon, enabling you to engage in more meaningful discussions and break through barriers when collaborating with programmers, architects and engineers across the table.The code examples provided in the book are intentionally designed to be simple and accessible to all, regardless of your programming background. Even if you are a C# or Python programmer and not familiar with Java, you will find the code examples easy to follow and understand.You willAcquire proficiency in both RPC-style and Messaging-style inter-microservice communicationConstruct microservices utilizing a combination of SQL (PostgreSQL) and NoSQL (MongoDB) databasesLeverage Liquibase, a database schema version control tool, and administer UI in conjunction with PostgreSQLLeverage both GraphQL and conventional REST approaches side by sideGain practical experience

On the Subject of "Java"
What are the limits of cultural critique? What are the horizons? What are the political implications? John Pemberton explores these questions in this far-reaching ethnographic and historical interpretation of cultural discourse in Indonesia since 1965. Pemberton considers in particular how the appearance of order under Soeharto's repressive New Order regime is an effect of an enigmatic politics founded upon routine appeals to cultural values.Through a richly textured ethnographic account of events ranging from national elections to weddings, Pemberton simultaneously elucidates and disturbs the contours of the New Order cultural imaginary. He pursues the fugitive signs of circumstances that might resist the powers of New Order rule through unexpected village practices, among graveyard spirits, and within ascetic refuges.Key to this study is a reexamination of the historical conditions under which a discourse of culture emerges. Providing a close reading of a number of Central Javanese manuscripts from the late eighteenth century on, Pemberton outlines the conditions of knowledge formation in Indonesia since the beginning of Dutch colonial control. As he overturns common assumptions concerning colonial encounters, he discloses the gradual emergence in these texts of a discursive figure inscribed in contrast to the increasingly invasive presence of the Dutch: a figuration of difference that came to be called "Java."
