Secure Web Application Development
Cyberattacks are becoming more commonplace and the Open Web Application Security Project (OWASP), estimates 94% of sites have flaws in their access control alone. Attacks evolve to work around new defenses, and defenses must evolve to remain effective. Developers need to understand the fundamentals of attacks and defenses in order to comprehend new techniques as they become available. This book teaches you how to write secure web applications.The focus is highlighting how hackers attack applications along with a broad arsenal of defenses. This will enable you to pick appropriate techniques to close vulnerabilities while still providing users with their needed functionality.Topics covered include:* A framework for deciding what needs to be protected and how strongly* Configuring services such as databases and web servers* Safe use of HTTP methods such as GET, POST, etc, cookies and use of HTTPS* Safe REST APIs* Server-side attacks and defenses such as injection and cross-site scripting* Client-side attacks and defenses such as cross-site request forgery* Security techniques such as CORS, CSP* Password management, authentication and authorization, including OAuth2* Best practices for dangerous operations such as password change and reset* Use of third-party components and supply chain security (Git, CI/CD etc)WHAT YOU'LL LEARN** Review the defenses that can used to prevent attacks* Model risks to better understand what to defend and how* Choose appropriate techniques to defend against attacks* Implement defenses in Python/Django applicationsWHO THIS BOOK IS FOR* Developers who already know how to build web applications but need to know more about security* Non-professional software engineers, such as scientists, who must develop web tools and want to make their algorithms available to a wider audience.* Engineers and managers who are responsible for their product/company technical security policyMATTHEW BAKER is the Head of Scientific Software and Data Management at ETH Zurich, Switzerland’s leading science and technology university, He leads a team of engineers developing custom software to support STEM research projects, as well as teaches computer science short courses.

Third Generation Internet Revealed
This book covers the inexorable exhaustion of the IPv4 address space, the interim fix to this based on Network Address Translation (NAT) and Private Addresses, and the differences between IPv4 and IPv6. It will help you understand the limitations and problems introduced by the use of NAT and introduce you to the far simpler network and software designs possible, using a larger, unified address space.IPv6, a mature and viable replacement for IPv4, is currently used by more than 36% of all global Internet traffic. Wireless telephone service providers in many countries have migrated their networks to IPv6 with great success. The elimination of NAT and Private Addresses has vastly simplified network design and implementation. Further, there are now enough public addresses allocated to accommodate all anticipated uses for the foreseeable future.Most networking products and software, especially open-source software, are already fully IPv6 compliant. Today, no businessshould purchase obsolete products that support only IPv4. The global IPv6 Forum estimates that there are millions of networking professionals still needing to learn the fundamentals of IPv6 technologies to move forward. This book is for them. With plans in place for a shutdown of IPv4 on global networks (“Sunset IPv4”) the time to learn is now. If you want a job in IT, especially network hardware or software, and you don’t know IPv6, you are already obsolete.WHAT YOU WILL LEARN* This book serves as a guide to all relevant Internet Engineering Task Force (IETF) standards Request for Comments (RFCs), organized by topic and discussed in plain language* Understand how IPv6 makes viable technologies such as multicast (for efficient global audio/video streaming), IPsec VPNs (for better security), and simpler VoIP* Take “edge computing” to the limit by eliminating intermediary servers made necessary by IPv4 NAT–for example, making connections directly from my node to yours* Discover how organizations can introduce IPv6 into existing IPv4 networks (“Dual Stack”), and then eliminate the legacy IPv4 aspects going forward (“Pure IPv6”) for the mandates going into place now (for example, US DoD requirements to move all networks to Pure IPv6)* Recognize that 5G networking (the Grand Convergence of conventional networks and wireless service) depends heavily on the advanced features IPv6 WHO THIS BOOK IS FORNetworking professionals. Readers should have at least some familiarity with the precursor protocol (IPv4) and legacy TCP/IP based networks. Some knowledge of network models, such as DoD four-layer model or OSI 7-layer model, is helpful to understand where the Internet Protocol fits into the larger picture. For network software developers using the Sockets API (in UNIX, Windows, etc.), this book will help you to understand the extensions to that API needed to work with IPv6.LAWRENCE E. HUGHES is a renowned expert in IPv6 and PKI. He has spoken at numerous IPv6 Summits worldwide. He created and ran one of the IPv6 Ready product certification centers for many years. He is an IPv6 Forum Gold Certified Trainer and was inducted into the IPv6 Hall of Fame in 2019.

Die Geheimnisse von Monkey Island
Unterhaltsam, kurzweilig, informativ: „Die Geheimnisse von Monkey Island – Auf Kapertour mit Pixel-Piraten“ ist DAS Buch für Fans der legendären Point’n’Click-Adventure-Reihe „Monkey Island“. Das Buch erschien zeitgleich zum neuen Teil von Monkey Island, der erstmals nach 30 Jahren wieder vom ursprünglichen Entwickler Ron Gilbert kreiert wurde."Macht, was ihr wollt, aber macht coole Sachen!" - George Lucas am 1. Mai 1982. Das war das einzige Ziel, das George Lucas seinen zwanzig jungen, ehrgeizigen, lustigen und schlecht frisierten Game-Designern als Rahmen für die Entwicklung von eigenen Computerspielen setzte. Lucasfilm Games und später LucasArts wurde in der Folgezeit zu einer legendären Spieleschmiede, auch durch die Veröffentlichung von The Secret of Monkey Island™ im Jahr 1990. Das bekannteste Point‘n‘Click-Adventure verdankt seinen legendären Ruf seiner herrlich anachronistischen Welt voller bunter Piraten und seinem von Monty Python inspirierten Humor, aber auch schlicht und einfach der Tatsache, dass es ein komplettes Genre revolutioniert hat. Dieses Buch ist eine Hommage an die Abenteuer von Guybrush Threepwood, einem genialen Piraten. Aber es möchte Ihnen auch in vielen Details schildern, wie Monkey Island durch seine einzigartige Erzählkunst zum Meilenstein in der Videospielgeschichte wurde.Darüber hinaus bietet es die Gelegenheit, auf die turbulente Historie von LucasArts und Telltale Games zurückzublicken, Rezepte für Voodoo-Grog zu entdecken, interaktive Piratenreggae-Songs zu lernen, auf einer mondänen Party unter 40-jährigen Geeks zu glänzen und Sprüche zu erkunden, die so scharf wie ein Entermesser sind (nützlich für Duelle oder Geburtstagsfeiern).

Building Quality Shaders for Unity®
Understand what shaders are and what they’re used for: Shaders are often seen as mystical and difficult to develop, even by skilled programmers, artists, and developers from other game design disciplines. This book dispels that idea by building up your shader knowledge in stages, starting with fundamental shader mathematics and how shader development mindset differs from other types of art and programming, and slowly delves into topics such as vertex and fragment shaders, lighting, depth-based effects, texture mapping, and Shader Graph.This book presents each of these topics with a comprehensive breakdown, the required theory, and some practical applications for the techniques learned during each chapter. The HLSL (High Level Shading Language) code and Shader Graphs will be provided for each relevant section, as well as plenty of screenshots.By the end of this book, you will have a good understanding of the shader development pipeline and you will be fully equipped to start making your own aesthetic and performant shader effects for your own games!YOU WILL LEARN TO• Use shaders across Unity’s rendering pipelines• Write shaders and modify their behavior with C# scripting• Use Shader Graph for codeless development• Understand the important math behind shaders, particularly space transformations• Profile the performance of shaders to identify optimization targetsWHO IS THIS BOOK FORThis book is intended for beginners to shader development, or readers who may want to make the jump from shader code to Shader Graph. It will also include a section on shader examples for those who already know the fundamentals of shaders and are looking for specific use cases. Daniel Ilett is an ambitious and motivated PhD student at the University of Warwick. He is a passionate game developer, specialising in shaders and technical art.
