As human activities moved to the digital domain, so did all the well-known malicious behaviors including fraud, theft, and other trickery. There is no silver bullet, and each security threat calls for a specific answer. One specific threat is that applications accept malformed inputs, and in many cases it is possible to craft inputs that let an intruder take full control over the target computer system. The nature of systems programming languages lies at the heart of the problem. Rather than rewriting decades of well-tested functionality, this book examines ways to live with the (programming) sins of the past while shoring up security in the most efficient manner possible. We explore a range of different options, each making significant progress towards securing legacy programs from malicious inputs. The solutions explored include enforcement-type defenses, which excludes certain program executions because they never arise during normal operation. Another strand explores the idea of presenting adversaries with a moving target that unpredictably changes its attack surface thanks to randomization. We also cover tandem execution ideas where the compromise of one executing clone causes it to diverge from another thus revealing adversarial activities. The main purpose of this book is to provide readers with some of the most influential works on run-time exploits and defenses. We hope that the material in this book will inspire readers and generate new ideas and paradigms.

Systems Software: Essential Concepts provides students with an accessible introduction to the knowledge and fundamentals that are necessary to understand software and hardware. The text also reviews implementation techniques to familiarize students with more complex software, such as operating systems and compilers, and prepare them to take more advance courses within the discipline. The book is divided into two key topical areas: compiler fundamentals and the basic mechanisms and data structures required to support operating systems. In the compiler section, students learn about the runtime environment, how to implement a scanner and a symbol table, and how to implement parsing and code generation for a virtual machine. To emphasize practical application, students are challenged to implement a small compiler. In the operating system domain, students gain an understanding of the interrupt mechanism, process and thread implementation, and process synchronization. Featuring a modern and practical approach, Systems Software is an ideal resource for courses in system programming, systems software, software development, and assembly language. It can also serve as a supplementary material for introductory operating system and compiler courses.

This book is the sixth volume of the successful book series on Robot Operating System: The Complete Reference. The objective of the book is to provide the reader with comprehensive coverage of the Robot Operating Systems (ROS) and the latest trends and contributed systems. ROS is currently considered as the primary development framework for robotics applications. There are seven chapters organized into three parts. Part I presents two chapters on the emerging ROS 2.0 framework; in particular, ROS 2.0 is become increasingly mature to be integrated into the industry. The first chapter from Amazon AWS deals with the challenges that ROS 2 developers will face as they transition their system to be commercial-grade. The second chapter deals with reactive programming for both ROS1 and ROS. In Part II, two chapters deal with advanced robotics, namely on the usage of robots in farms, and the second deals with platooning systems. Part III provides three chapters on ROS navigation. The first chapter deals with the use of deep learning for ROS navigation. The second chapter presents a detailed tuning guide on ROS navigation and the last chapter discusses SLAM for ROS applications. I believe that this book is a valuable companion for ROS users and developers to learn more ROS capabilities and features.

Two, to provide a quick and valuable on-the-job resource to HP-UX administrators, administrators of other UNIX operating system software, IT managers, programmers, and DBAs working in the HP-UX environment. Three, to provide an easy-to-understand guide to novice and IT/non-HP-UX administrators who intend to learn HP-UX from the beginning. This book contains 33 chapters. The book is organized in such a way that it helps its audience understand concepts, implementation procedures, some basic troubleshooting, command syntax, configuration files, and daemons involved. There are three key areas: UNIX fundamentals, HP-UX system administration, and HP-UX network administration. 1.UNIX Fundamentals covers the basics of UNIX. Most information is not specific to a particular UNIX flavor, but rather includes general UNIX concepts, file manipulation and security techniques, shell and awk programming, vi editor, basic commands, and other topics. Chapters 01 through 06 and chapter 21 cover this area. Unlike many other similar books, a chapter on shell scripting is presented after covering HP-UX System Administration chapters. This is done intentionally to provide readers with some practical examples based on the knowledge they have gained from UNIX Fundamentals and HP-UX System Administration chapters. 2.HP-UX System Administration covers the HP-UX-specific system administration concepts and topics including HP-UX installation methods; software and patch management; user and group account administration; disk and device file management; LVM and file system administration; swap space and printer management; system startup and shutdown procedures; kernel reconfiguration techniques; backup, restore, and system recovery functions; job automation and process control; system logging and performance monitoring; and so on. Chapters 07 through 20 cover this area. 3.HP-UX Network Administration covers HP-UX network administration concepts and topics such as OSI and TCP/IP models; network hardware overview; LAN card administration; IP subnetting and routing techniques; network troubleshooting tools; system startup services; naming services such as DNS, NIS, and LDAP; File sharing tools viz. NFS and AutoFS; Time synchronization using NTP; internet services administration; BootP/TFTP services; system security; and so on. Chapters 22 through 33 cover this area. The beginning of each chapter highlights objectives covered. The end of each chapter includes a summary as to what is learnt in the chapter. Throughout the book tables, figures, screen shots, and examples are given to explain concepts and tasks. The output generated as a result of running commands is highlighted in light grey background to differentiate it with surrounding text. The book includes several appendices one of which contains more than 550 practice exam questions. Tables of commands, important files, and service daemons are included in separate appendices.

Getting Started with OpenVMS System Management gives new VMS system managers a jumpstart in managing this powerful and reliable operating system. Dave Miller describes the essentials of what an OpenVMS System Manager will have to manage. He defines areas of OpenVMS System Management and describes why each is important and how it fits into the larger management task. Even though some OpenVMS management concepts are unique (for instance quotas), many concepts (such as account creation) have counterparts in UNIX and Windows NT. So, wherever possible, Miller points out to his readers the parallel to other systems.
The book is intended as a precursor to Baldwin's OpenVMS System Management Guide and various OpenVMS documents. Thus it refers the reader to other books for the detailed management steps. Getting Started with OpenVMS System Management is a great introduction to the material Steve Hoffman and Dave Miller are revising for the OpenVMS System Management Guide, 2E.
-Permits experienced system managers to begin managing OpenVMS more quickly
-Dovetails with other Digital Press publications for easier reference by the OpenVMS manager
-Points you in the right direction for the complete documentation on each issue
-BONUS FEATURE! Includes excerpts from five key DP OpenVMS books

OpenVMS professionals have long enjoyed a robust, full-featured operating system running the most mission-critical applications in existence.

Unlike so many books that focus on how to use Linux, Linux and the Unix Philosophy explores the "way of thinking that is Linux" and why Linux is a superior implementation of this highly capable operating system.
This book is a revision and expansion of a computer science classic. Every chapter has been thoroughly updated with Linux coverage.
Linux and the Unix Philosophy falls squarely between the "softer" texts on iterative software design and project management and the "how-to" technical texts. Thus far, no one has come out with a book that addresses this topic, either in the Unix space or the Linux space. Linux and the Unix Philosophy covers the same ground as the first edition, while it also presents bold new ideas about Linux and Open Source.
.Concise list of philosophy tenets makes it a handy quick reference
.Anecdotal examples personalize the book for the reader
.Conversational style makes it easy and joyful to read"

Dealing with system problems from user login failures to server crashes--is a critical part of a system administrator's job. A down system can cost a business thousands of dollars per minute. But there is little or no information available on how to troubleshoot and correct system problems; in most cases, these skills are learned in an ad-hoc manner, usually in the pressure-cooker environment of a crisis. This is the first book to address this lack of information.
The authors (both experienced Tru64 UNIX support engineer for Compaq) systematically present the techniques and tools needed to find and fix system problems. The first part of the book presents the general principles and techniques needed in system troubleshooting. These principles and techniques are useful not only for UNIX system administrators, but for anyone who needs to find and fix system problems. After this foundation, the authors describe troubleshooting tools used in the UNIX environment. The remainder of the book covers specific areas of the Tru64 UNIX operating system in detail: listing common problems, their causes, how to detect them, and how to correct them. Each chapter includes a "Before You Call Support" section that details the most important things to check and correct before it's necessary to call Compaq technical support. The authors also include decision trees to help the reader systematically isolate particular problem types.
