Book SynopsisLearn how to detect and prevent the hacking of medical equipment at hospitals and healthcare facilities. A cyber-physical attack on building equipment pales in comparison to the damage a determined hacker can do if he/she gains access to a medical-grade network as a medical-grade network controls the diagnostic, treatment, and life support equipment on which lives depend. News reports inform us how hackers strike hospitals with ransomware that prevents staff from accessing patient records or scheduling appointments. Unfortunately, medical equipment also can be hacked and shut down remotely as a form of extortion. Criminal hackers will not ask for a $500 payment to unlock an MRI, PET or CT scan, or X-ray machinethey will ask for much more. Litigation is bound to follow and the resulting punitive awards will drive up hospital insurance costs and healthcare costs in general. This will undoubtedly result in increased regulations for hospitals and higher costs for compliance.

APress Patterns in the Machine
Book SynopsisDiscover how to apply software engineering patterns to develop more robust firmware faster than traditional embedded development approaches. In the authors'' experience, traditional embedded software projects tend towards monolithic applications that are optimized for their target hardware platforms. This leads to software that is fragile in terms of extensibility and difficult to test without fully integrated software and hardware. Patterns in the Machine focuses on creating loosely coupled implementations that embrace both change and testability.This book illustrates how implementing continuous integration, automated unit testing, platform-independent code, and other best practices that are not typically implemented in the embedded systems world is not just feasible but also practical for today''s embedded projects.After reading this book, you will have a better idea of how to structure your embedded software projects. You will recognize that while writing unit tests, creating simulators, and implementing continuous integration requires time and effort up front, you will be amply rewarded at the end of the project in terms of quality, adaptability, and maintainability of your code. What You Will Learn Incorporate automated unit testing into an embedded project Design and build functional simulators for an embedded project Write production-quality software when hardware is not available Use the Data Model architectural pattern to create a highly decoupled design and implementation Understand the importance of defining the software architecture before implementation starts and how to do it Discover why documentation is essential for an embedded project Use finite state machines in embedded projects Who This Book Is ForMid-level or higher embedded systems (firmware) developers, technical leads, software architects, and development managers.Table of Contents1: Introduction2: Core Concepts3: Design Theory For Embedded Programming4: Persistent Storage Example5: Software Architecture6: Automated Unit Testing7: Functional Simulator8: Continuous Integration9: Data Model10: Finite State Machines11: Documentation12: File Organization and Naming13: More About Late Bindings14: Main and Initialization15: More Best Practices16: Example Code17: Rules For DevelopmentAppendix A: TerminologyAppendix B: UML Cheat SheetAppendix C: Notation for State MachinesAppendix D: Coding ConventionsAppendix E: Why C++

APress Salt Open
Book SynopsisThere is a rapid growth of automation in server rooms and data centers. The days of having many administrators running around busily configuring and maintaining servers are gone and have been replaced with droves of Salt-Minions; agents beavering away on the target nodes ensuring the configuration is as specified. This book covers Salt Open (also known as SaltStack Open) from the ground up and shows you how to work with two Linux distributions. You'll see how Salt Open is duplicated with ArubaOS and IOS networking devices, which can be configured without the underlying OS. As you step through the configuration options, you'll learn how to run remote execution modules from the CLI before looking at stateful configuration using SLS files. Moving on, you'll learn how to configure the systems where you also need to monitor your devices and that is when reactors and beacons come into play.

Book SynopsisAn Update of the Most Practical A-to-Z Operating System BookWidely lauded for avoiding the typical black box approach found in other operating system textbooks, the first edition of this bestselling book taught readers how an operating system works and explained how to build it from the ground up. Continuing to follow a logical pattern for system design, Operating System Design: The Xinu Approach, Second Edition removes the mystery from operating system design and consolidates the body of material into a systematic discipline. It presents a hierarchical design paradigm that organizes major operating system components in an orderly, understandable manner. The book guides readers through the construction of a conventional process-based operating system using practical, straightforward primitives. It gives the implementation details of one set of primitives, usually the most popular set. Once readers understand how priTrade Review"What sets this book aside from the mass of books on operating systems is its focus on a single real-world operating systems, namely Xinu, which is a commercially used, yet lean, clearly designed, modular operating system for embedded, single-core systems. … The book is surprisingly easy to read; essential data structures and algorithms are presented in source code and discussed adequately, allowing for a very good understanding of the entire operating system. … an ideal book for anyone who aims to understand one operating system in detail, in particular for those working with embedded systems."—Zentralblatt MATH 1314Praise for the First Edition:"Operating System Design: The Xinu Approach is the best book for students and professionals to learn how a computer operating system works. The computer code, along with clear, concise explanations, is simply the best way to learn OS. Readers who study this book carefully will benefit greatly and find it time well spent."—John C. Lin, Bell Labs"… [the author’s] focused, clear, and thorough writing have given ‘systematic’ a new meaning (or perhaps restored its original one). … non-OS specialists also stand to learn much of what they generally need to know from this excellent book. Furthermore, it is no faint praise for me to say that the book’s seamless integration of source code listings into the text … is the best I’ve encountered and works very well indeed. Superior and consistently followed C-language coding conventions give further evidence of the meticulousness with which this book was written. … a most outstanding and practical A-to-Z OS book. It has my highest recommendation."—George Hacken, Computing Reviews, April 2012"This Xinu book is the best operating systems book on the market because it removes the black magic and explains how to build an OS from the ground up.
