Pre-Revolutionary Caracas: Politics, Economy, and Society 1777-1811 By P. Michael McKinley 2002 | 264 Pages | ISBN: 052152704X | PDF | 7 MB Almost invariably, late-colonial Caracas has been described as a society full of tensions and a colony at odds with the imperial order. This study, in contrast, portrays a colony, which grew, prospered and matured within the confines of Empire. It depicts the late 1700s as the golden age of caraque?o colonial society and suggests that it was no accident that this late renaissance created an environment which bred the self-confident men who led much of Spanish America to independence. The causes of the independence struggle, and the violence, which accompanied it, are considered in the context of the imperial crisis provoked by Napoleon's invasion of Spain. The findings of this study are based on an exceptionally varied array of new data on the economy and society of late eighteenth-century Caracas, of which a collection of 800 wills is the most impressive.

Praktische Einführung in Hardware Hacking: Sicherheitsanalyse und Penetration Testing für IoT-Geräte und Embedded Devices (mitp Professional) Deutsch | 17 Dec. 2019 | ASIN: B082V8NJ4P | 253 Seiten | EPUB (True) | 26.57 MB Schwachstellen von IoT- und Smart-Home-Geräten aufdecken Hardware, Firmware und Apps analysieren und praktische Tests durchführen Zahlreiche Praxisbeispiele wie Analyse und Hacking elektronischer Türschlösser, smarter LED-Lampen u.v.m. Smarte Geräte sind allgegenwärtig und sie sind leicht zu hacken - umso mehr sind Reverse Engineers und Penetration Tester gefragt, um Schwachstellen aufzudecken und so Hacking-Angriffen und Manipulation vorzubeugen. In diesem Buch lernen Sie alle Grundlagen des Penetration Testings für IoT-Geräte. Die Autoren zeigen Schritt für Schritt, wie ein Penetrationstest durchgeführt wird: von der Einrichtung des Testlabors über die OSINT-Analyse eines Produkts bis hin zum Prüfen von Hard- und Software auf Sicherheitslücken - u.a. anhand des OWASP-Standards. Sie erfahren darüber hinaus, wie Sie die Firmware eines IoT-Geräts extrahieren, entpacken und dynamisch oder statisch analysieren. Auch die Analyse von Apps, Webapplikationen und Cloudfunktionen wird behandelt. Außerdem finden Sie eine Übersicht der wichtigsten IoT-Protokolle und ihrer Schwachstellen. Es werden nur grundlegende IT-Security-Kenntnisse (insbesondere in den Bereichen Netzwerk- und Applikationssicherheit) und ein sicherer Umgang mit Linux vorausgesetzt. Die notwendigen Elektronik- und Hardwaredesign-Grundlagen geben Ihnen die Autoren mit an die Hand. Aus dem Inhalt: Testumgebung einrichten Vorbereitende OSINT-Analyse Elektronik-Grundlagen Einführung in das Hardware-Design von IoT-Geräten: 8-/32-Bit-Controller Android Embedded Devices All-in-One SoC Hardware-Analyse und Extraktion von Firmware Dateisysteme von IoT-Geräten Statische und dynamische Firmware-Analyse IoT-Protokolle und ihre Schwachstellen: Bluetooth LE ZigBee MQTT App-Analyse anhand des OWASP-Standards Testen von Backend-Systemen, Webapplikationen und Cloud-Umgebungen  Pragmatism and Educational Research (Philosophy, Theory, and Educational Research) By Gert J.
