45 Elektronik-Projekte für den Raspberry Pi
Der Raspberry Pi stellt einen sehr preiswerten, aber doch vollwertigen Computer dar, an den auf einfache Weise verschiedenste Elektronik angeschlossen werden kann. Dieses Buch geht auf eine der Stärken des Raspberry Pi ein: die Kombination von Elektronik und Software.Nach einer kurzen Einführung zum Raspberry Pi wird auf die benötigte Software eingegangen. Im Anschluss wird das Linux-Betriebssystem kurz vorgestellt – gefolgt von einer Einführung in die Programmierung mit Bash, Python und JavaScript. Der Schwerpunkt liegt dabei auf Python. Die Erläuterungen sind in allen Fällen kurz und bündig und trotzdem so ausführlich, dass das Notwendigste besprochen wird, um die folgenden Projekte zu verstehen und individuell anzupassen.Dieses Buch beschreibt 45 spannende und interessante Projekte, wie zum Beispiel ein Wechselblinklicht, eine Motorregelung, Erzeugen und Verarbeiten analoger Signale, ein digitales Thermometer, ein Lichtmesser. Aber auch kompliziertere Projekte wie eine Motor-Geschwindigkeitsregelung, ein Webserver mit CGI (Common Gateway Interface) und Client-Server-Programme werden vorgestellt. Sie können dieses Buch als Projektbuch verwenden und die Projekte nachbauen, um sie dann in der Praxis einzusetzen. Durch die ausführliche Beschreibung mit Schaltplänen und Fotos gestaltet sich der Aufbau auf dem Steckbrett recht einfach.Sie können dieses Buch auch als Lehrbuch verwenden. Bei jedem Projekt wird erklärt, warum es auf diese Art und Weise ausgeführt ist. Sie lernen viel über den Raspberry Pi, Python und die verwendeten Bauteile, so dass Sie selbst die Projekte anpassen, nach eigenen Wünschen erweitern oder mehrere Projekte miteinander kombinieren können.Um Ihnen die Software-Installation zu erleichtern, hat der Autor das Betriebssystem und alle Programmbeispiele auf einer SD-Karte zusammengetragen. Passend zu den Projekten ist neben dieser SD-Karte auch ein Hardware-Starterkit bei Elektor erhältlich.Bert van Dam ist freiberuflicher Autor von Büchern, Kursen und Artikeln über PIC- und ARM Mikrocontroller, Arduino, Raspberry Pi, PCs, Künstliche Intelligenz und die Programmiersprachen JAL, C, Assembler, Python und Flowcode.
Grafisch programmieren, messen und steuern mit Processing
Ein Blick in die einschlägigen Internetforen zeigt, dass das Programmieren immer noch in der Gruppe der beliebten Hobbys rangiert. Wo dem Hobbyprogrammierer früher eine Reihe bekannter und populärer Programmiersprachen zur Verfügung standen, ist es heute relativ übersichtlich geworden: Außer C++, Java und Visual Basic gibt es wenig bekannte und beliebte Programmiersprachen. Was fehlt, ist eine Programmiersprache, die für Laien fast so einfach zu handhaben ist wie die alten BASIC-Versionen, deren Leistung und Features dennoch an die Möglichkeiten und die Power moderner Windows-Rechner angepasst sind. Diese Programmiersprache existiert und heißt Processing.Das vorliegende Buch führt den Leser in diese visuelle Programmiersprache ein. Das Buch richtet sich an Leser, die bereits allgemeine Erfahrungen im Umgang mit Programmiersprachen besitzen und wissen, worum es sich bei Strings, Arrays oder Schleifen handelt. Der Autor zeigt anhand vieler kurzer Programmbeispiele, wie einfach es ist, mit Processing auch leistungsfähige Software zu programmieren und sich dabei auf eine nur geringe Anzahl von Befehlen, Anweisungen und Funktionen zu beschränken.Die in diesem Buch vorgestellten Programme sind zum Teil Hardware-orientiert, wobei auch die Erfassung von Daten und die Steuerung von Hardware mittels des bekannten Mikrocontrollers Arduino einer Rolle spielt. Kurz und gut: Ein Buch für alle, die eine schnell und einfach zu programmierende Software mit elektronischer Hardware kombinieren und das Ganze über maßgeschneiderte Benutzeroberflächen steuern möchten.Kurt Diedrich ist gelernter Geologe und gehört zu den langjährigen freien Mitarbeitern des ElektorVerlags. Neben dem nun schon seit über 25 Jahren erfolgreichen "Dauerbrenner" Operationsverstärker gar nicht schwer stammen auch verschiedene Bücher zum Thema Programmierung aus seiner Feder. Auf seiner Webseite www.subroutine. info veröffentlicht er in unregelmäßigen Abständen die neuesten Ergebnisse seiner Arbeit.

Privileged Attack Vectors
See how privileges, insecure passwords, administrative rights, and remote access can be combined as an attack vector to breach any organization. Cyber attacks continue to increase in volume and sophistication. It is not a matter of if, but when, your organization will be breached. Threat actors target the path of least resistance: users and their privileges.In decades past, an entire enterprise might be sufficiently managed through just a handful of credentials. Today’s environmental complexity has seen an explosion of privileged credentials for many different account types such as domain and local administrators, operating systems (Windows, Unix, Linux, macOS, etc.), directory services, databases, applications, cloud instances, networking hardware, Internet of Things (IoT), social media, and so many more. When unmanaged, these privileged credentials pose a significant threat from external hackers and insider threats. We are experiencing an expanding universe of privileged accounts almost everywhere.There is no one solution or strategy to provide the protection you need against all vectors and stages of an attack. And while some new and innovative products will help protect against or detect against a privilege attack, they are not guaranteed to stop 100% of malicious activity. The volume and frequency of privilege-based attacks continues to increase and test the limits of existing security controls and solution implementations.PRIVILEGED ATTACK VECTORS details the risks associated with poor privilege management, the techniques that threat actors leverage, and the defensive measures that organizations should adopt to protect against an incident, protect against lateral movement, and improve the ability to detect malicious activity due to the inappropriate usage of privileged credentials.This revised and expanded second edition covers new attack vectors, has updated definitions for privileged access management (PAM), new strategies for defense, tested empirical steps for a successful implementation, and includes new disciplines for least privilege endpoint management and privileged remote access.WHAT YOU WILL LEARN* Know how identities, accounts, credentials, passwords, and exploits can be leveraged to escalate privileges during an attack * Implement defensive and monitoring strategies to mitigate privilege threats and risk * Understand a 10-step universal privilege management implementation plan to guide you through a successful privilege access management journey* Develop a comprehensive model for documenting risk, compliance, and reporting based on privilege session activityWHO THIS BOOK IS FORSecurity management professionals, new security professionals, and auditors looking to understand and solve privilege access management problemsMOREY J. HABER is Chief Technology Officer at BeyondTrust. He has more than 20 years of IT industry experience, and has authored three Apress books: Asset Attack Vectors and Identity Attack Vectors, as well as the first edition of Privileged Attack Vectors.

Programming with Node-RED
The Internet of Things (IoT) is becoming a major application area for embedded systems. As a result, more and more people are becoming interested in learning about embedded design and programming. Technical colleges and universities are moving away from legacy 8 and 16-bit microcontrollers and are introducing 32-bit embedded microcontrollers to their curriculums. Many IoT applications demand precision, high processing power, and low power consumption.Produced by IBM, Node-RED is an open-source visual editor for wiring the Internet of Things. Node-RED comes with a large number of nodes to handle a multitude of tasks. The required nodes are selected and joined together to perform a particular task. Node-RED is based on flow type programming where nodes are configured and joined together to form an application program. There are nodes for performing complex tasks, including web access, Twitter, E-mail, HTTP, Bluetooth, MQTT, controlling GPIO ports, etc. One particularly nice aspect of Node-RED is that the programmer does not need to learn how to write complex programs. For example, an email can be sent by simply joining nodes together and writing only a few lines of code.The aim of this book is to teach how Node-RED can be used in projects. The main hardware platform used with most of the projects in this book is Raspberry Pi 4. Chapters are included to show how Node-RED can be also be used with Arduino Uno, ESP32 DevKitC, and the ESP8266 NodeMCU microcontroller development boards.Prof. Dr. Dogan Ibrahim is a Fellow of the Institution of Electrical Engineers. He is the author of over 60 technical books, published by publishers including Wiley, Butterworth, and Newnes.

C Programming with Arduino
Technology is constantly changing. New microcontrollers become available every year. The one thing that has stayed the same is the C programming language used to program these microcontrollers. If you would like to learn this standard language to program microcontrollers, then this e-book (pdf) is for you!Arduino is the hardware platform used to teach the C programming language as Arduino boards are available worldwide and contain the popular AVR microcontrollers from Atmel.Atmel Studio is used as the development environment for writing C programs for AVR microcontrollers. It is a full-featured integrated development environment (IDE) that uses the GCC C software tools for AVR microcontrollers and is free to download.At a glance:• Start learning to program from the very first chapter• No programming experience is necessary• Learn by doing - type and run the example programs• A fun way to learn the C programming language• Ideal for electronic hobbyists, students and engineers wanting to learn the C programming language in an embedded environment on AVR microcontrollers• Use the free full-featured Atmel Studio IDE software for Windows• Write C programs for 8-bit AVR microcontrollers as found on the Arduino Uno and MEGA boards• Example code runs on Arduino Uno and Arduino MEGA 2560 boards and can be adapted to run on other AVR microcontrollers or boards• Use the AVR Dragon programmer / debugger in conjunction with Atmel Studio to debug C programsWarwick A.

Programming the Finite State Machine with 8-Bit PICs in Assembly and C
This practical guide is aimed at electronics students and hobbyists. It is intended to be a valuable aid in writing programs using Finite State Machines (FSMs) in assembly language using 8-bit PIC microcontrollers. The last two chapters introduce the use of the C programming language and make a direct comparison with development in Assembly.An FSM is a way of writing a program to make it easier to produce and modify. The machine is abstract in that it is just the structure of the program. This abstract machine can be represented by drawing a diagram on paper. The diagram is independent of the programming language used. The FSM chart gives a complete description of what the program does. It can then be implemented as source code.The book should appeal to those with an interest in the combination of electronics and software and have an interest in how things work. The book will describe writing code for two particular microcontrollers: The 12F1822 and 16F1823. Both are mid-range and inexpensive. To read and write the programs to and from the PICs, all that is required is an FTDI TTL level USB lead (TTL-232R-5V-WE) in addition to two programs that are both available for free download as executable files and source code from Elektor. Microsoft Windows or Linux can be used.The PIC programs are written in assembly language. This goes against the conventional wisdom of using a higher-level language such as C. One reason for this is that assembly is a good way of learning what is happening at the lowest level. This is important as microcontroller programming requires an understanding of the chip. Another reason for using the finite state machine approach is that it makes assembly programs surprisingly easy to follow. One of the main obstacles in the way of getting started with embedded programming is the installation and learning of new software tools.The emphasis of this book is on making things straightforward with as little complication as possible. Therefore you can concentrate on understanding the code. Real projects aren't just about coding: our software has to do something real. As a consequence, a chapter deals with a method of circuit board construction.All coding is done in a text editor of your choosing. The command line is used for running programs. If you are a Windows user, you might look at this as old fashioned. This is actually an efficient way of doing things: simple scripts for repetitive tasks save lots of mouse clicks. The last two chapters give an introduction to programming in C using the XC8 compiler. Again this is done using a text editor and the command line.The intention has been to achieve results using an inexpensive microcontroller with simple command line tools. Much emphasis is placed on using Microchip's datasheet as this is the best place to get correct detailed informationAndrew Pratt served for 25 years in the Royal Air Force as an Aircraft Technician. He holds a Higher National Certificate in electrical and electronicengineering and an Honours Degree from the Open University. He continued his career working in industrial controls.
