Big Data - Big Accountability
Mit dem Phänomen „Big Data“ als Teil einer datengetriebenen Zukunft verbinden sich seit Jahren enorme Hoffnungen und große Ängste. Immer mehr Akteure aus dem privaten und öffentlichen Sektor sammeln und nutzen solche Datenmassen zu vielfältigen Zwecken. Dabei stellt sich aus datenschutzrechtlicher Perspektive die Frage: Ist es möglich, Big-Data-Verfahren im Einklang mit der Datenschutz-Grundverordnung durchzuführen oder bedeutet Big Data zwangsläufig „Small Privacy“? Am Beispiel der Betrugsbekämpfung mit Big Data in der Kraftfahrzeughaftpflichtversicherung analysiert Constantin Herfurth die datenschutzrechtlichen Rahmenbedingungen und entwickelt neue Modelle, um bewährte Datenschutzgrundsätze innovativ anwenden zu können und eine "Big Accountability" zu schaffen. Dabei zeichnet er nicht nur ein differenzierteres Bild von Big Data, sondern zeigt auch Wege für eine datenschutzkonforme Gestaltung auf und regt die Weiterentwicklung bestehender Mechanismen und Instrumente der Datenschutz-Grundverordnung an.CONSTANTIN HERFURTH war als wissenschaftlicher Mitarbeiter mit dem Forschungsschwerpunkt Big Data und Datenschutz von 2016 bis 2018 am Fachgebiet Öffentliches Recht, IT-Recht und Umweltrecht von Prof. Dr. Gerrit Hornung, LL.M. an der Universität Kassel tätig. Seit 2018 arbeitet er als Rechtsanwalt für eine internationale Kanzlei in München und berät zu Datenschutz und Cybersecurity.Einführung.- Versicherungsbetrug in der Kraftfahrzeug-Haftpflichtversicherung.- Bekämpfung von Versicherungsbetrug mittels Big Data.- Rechtsrahmen des europäischen und nationalen Datenschutzrechts.- Anwendungsbereich der Datenschutz-Grundverordnung.- Anforderungen der Datenschutz-Grundverordnung.- Zusammenfassung.

ESP32 steuert Roboterfahrzeug
• Open-Source-Code mit Arduino IDE und PlatformIO• Autonomes Fahren: GPS, Accelerometer, Gyroskop• PS3-ControllerMikrocontroller wie der Arduino und Einplatinenrechner wie der Raspberry Pi haben sich zu beliebten Komponenten entwickelt. Dritter im Bunde ist der ESP32 der Firma Espressif. Mikrocontroller dieser Baureihe zeichnen sich durch eine Vielzahl implementierter Funktionen aus, die bei einem Arduino konventioneller Prägung mit einem Atmel-AVR-Mikrocontroller erst mit weiterer Hardware möglich sind. Prominentes Beispiel sind hier die WiFi- und Bluetooth- Funktionalitäten. Gegenüber einem Raspberry Pi zeichnen sie sich durch einen deutlich geringeren Preis aus.Allgemeine Informationen für die Realisierung eines Roboterauto- Projekts mit dem ESP32 sind leicht zu finden. Dabei handelt es sich aber oft nur um Ausführungen zu einem Teilaspekt, ohne inhaltliche oder funktionale Abstimmung. So ist nicht nur die Beschaffung der benötigten Informationen mühselig und zeitaufwändig, sie kann auch außerordentlich fehlerträchtig sein.Ansatzpunkt dieses Buches ist, diese Lücke zu schließen. Es geht auf verschiedene Möglichkeiten eines Chassis ein, vermittelt nötige Kenntnisse und führt schrittweise von einer einfachen Motorsteuerung zu einem komplexen sensor- und sprachgesteuerten Roboterauto.

Edge Networking
The Internet of Edges is a new paradigm whose objective is to keep data and processing close to the user. This book presents three different levels of Edge networking: MEC (Multi-access Edge Computing), Fog and Far Edge (sometimes called Mist or Skin). It also reviews participatory networks, in which user equipment provides the resources for the Edge network.Edge networks can be disconnected from the core Internet, and the interconnection of autonomous edge networks can then form the Internet of Edges.This book analyzes the characteristics of Edge networks in detail, showing their capacity to replace the imposing Clouds of core networks due to their superior server response time, data security and energy saving.KHALDOUN AL AGHA is a professor at the University of Paris-Saclay, France, and an expert in telecommunications and networks.

Practical Database Auditing for Microsoft SQL Server and Azure SQL
Know how to track changes and key events in your SQL Server databases in support of application troubleshooting, regulatory compliance, and governance. This book shows how to use key features in SQL Server ,such as SQL Server Audit and Extended Events, to track schema changes, permission changes, and changes to your data. You’ll even learn how to track queries run against specific tables in a database.Not all changes and events can be captured and tracked using SQL Server Audit and Extended Events, and the book goes beyond those features to also show what can be captured using common criteria compliance, change data capture, temporal tables, or querying the SQL Server log. You will learn how to audit just what you need to audit, and how to audit pretty much anything that happens on a SQL Server instance. This book will also help you set up cloud auditing with an emphasis on Azure SQL Database, Azure SQL Managed Instance, and AWS RDS SQL Server.You don’t need expensive, third-party auditing tools to make auditing work for you, and to demonstrate and provide value back to your business. This book will help you set up an auditing solution that works for you and your needs. It shows how to collect the audit data that you need, centralize that data for easy reporting, and generate audit reports using built-in SQL Server functionality for use by your own team, developers, and organization’s auditors.WHAT YOU WILL LEARN* Understand why auditing is important for troubleshooting, compliance, and governance* Track changes and key events using SQL Server Audit and Extended Events* Track SQL Server configuration changes for governance and troubleshooting* Utilize change data capture and temporal tables to track data changes in SQL Server tables* Centralize auditing data from all your databases for easy querying and reporting* Configure auditing on Azure SQL, Azure SQL Managed Instance, and AWS RDS SQL Server WHO THIS BOOK IS FORDatabase administrators who need to know what’s changing on their database servers, and those who are making the changes; database-savvy DevOps engineers and developers who are charged with troubleshooting processes and applications; developers and administrators who are responsible for generating reports in support of regulatory compliance reporting and auditingJOSEPHINE BUSH has more than 10 years of experience as a database administrator.

The Art of Site Reliability Engineering (SRE) with Azure
Gain a foundational understanding of SRE and learn its basic concepts and architectural best practices for deploying Azure IaaS, PaaS, and microservices-based resilient architectures.The book starts with the base concepts of SRE operations and developer needs, followed by definitions and acronyms of Service Level Agreements in real-world scenarios. Moving forward, you will learn how to build resilient IaaS solutions, PaaS solutions, and microservices architecture in Azure. Here you will go through Azure reference architecture for high-available storage, networking and virtual machine computing, describing Availability Sets and Zones and Scale Sets as main scenarios. You will explore similar reference architectures for Platform Services such as App Services with Web Apps, and work with data solutions like Azure SQL and Azure Cosmos DB.Next, you will learn automation to enable SRE with Azure DevOps Pipelines and GitHub Actions. You’ll also gain an understanding of how an open culture around post-mortems dramatically helps in optimizing SRE and the overall company culture around managing and running IT systems and application workloads. You’ll be exposed to incent management and monitoring practices, by making use of Azure Monitor/Log Analytics/Grafana, which forms the foundation of monitoring Azure and Hybrid-running workloads.As an extra, the book covers two new testing solutions: Azure Chaos Studio and Azure Load Testing. These solutions will make it easier to test the resilience of your services.After reading this book, you will understand the underlying concepts of SRE and its implementation using Azure public cloud.WHAT WILL YOU LEARN:* Learn SRE definitions and metrics like SLI/SLO/SLA, Error Budget, toil, MTTR, MTTF, and MTBF* Understand Azure Well-Architected Framework (WAF) and Disaster Recovery scenarios on Azure* Understand resiliency and how to design resilient solutions in Azure for different architecture types and services* Master core DevOps concepts and the difference between SRE and tools like Azure DevOps and GitHub* Utilize Azure observability tools like Azure Monitor, Application Insights, KQL or Grafana* Understand Incident Response and Blameless Post-Mortems and how to improve collaboration using ChatOps practices with Microsoft toolsWHO IS THIS BOOK FOR:IT operations administrators, engineers, security team members, as well as developers or DevOps engineers.UNAI HUETE BELOKI is a Microsoft Technical Trainer (MTT) working at Microsoft, based in San Sebastian (Spain).From February 2017 to July 2020 he worked as a PFE (Premier Field Engineer), offering support and education as a DevOps Expert to Microsoft customers all around EMEA , mainly focused in the following technologies: GitHub, Azure DevOps, Azure Cloud Architecture and Monitoring, Azure AI/Cognitive Services.Since July 2020, he has worked as a Microsoft Technical Trainer (MTT) on the technologies mentioned above, and served as the MTT lead for the AZ-400 DevOps Solutions exam, helping shape content of the exam/course.In his free time, he loves traveling, water sports like surfing and spearfishing, and mountain-related activities such as MTB and snowboarding.CHAPTER 1: THE FOUNDATION OF SREThis chapter lays out the foundation of Site Resiliency Engineering, founded by Google. From the base concepts of how IT Operations and Developers need to collaborate, to how SRE helps organizations in running business-critical workloads without major downtimeCHAPTER 2: SERVICE LEVEL MANAGEMENT DEFINITIONS AND ACRONYMS AND THEIR MEANING IN A REAL-LIFE CONTEXTThis Chapter describes all common Service Level Agreements (SLA) definitions and acronyms, looked at from a real-world scenario to provide a clear understandingo Some examples, SLA, SLO, MTTF, MTBF, MTTR,…CHAPTER 3: ARCHITECTING RESILIENT INFRASTRUCTURE AS A SERVICE (IAAS) SOLUTIONS IN AZURESRE is all about providing ultimate uptime of your organization’s workloads, and this chapter will cover that in relation to Azure IaaS Compute solutions. Explaining the Azure reference architecture for high-available storage, networking and Virtual Machine computing, describing Availability Sets and Zones and ScaleSets as main scenarios. It will also touch on preparing for Disaster Recovery with Azure Backup and Azure Site Recovery, helping you to quickly mitigate outages in case of a failureCHAPTER 4: ARCHITECTING RESILIENT PLATFORM AS A SERVICE (PAAS) SOLUTIONS IN AZUREFollowing on the scenario of Virtual Machines, this chapter details similar reference architectures for Platform Services such as App Services with Web Apps, but also touching on data solutions like Azure SQL and Azure Cosmos DBCHAPTER 5: ARCHITECTING RESILIENT SERVERLESS AND MICROSERVICES ARCHITECTURES IN AZUREThis third chapter in the reference architecture topic describes how to build high-available, business-critical scenarios using Serverless Functions and Azure LogicApps, as well as Microservices scenarios using Azure Container Instance and Azure Kubernetes Service (AKS).CHAPTER 6: AUTOMATION TO ENABLE SRE WITH AZURE DEVOPS PIPELINES / GITHUB ACTIONSAutomation is the cornerstone to SRE, allowing businesses to not only deploy new workloads in a easy way, but also relying on SRE to avoid critical outages or, when an outage occurs, relying on automation to mitigate the problem as fast as possible. Sharing several examples from both Azure DevOps Pipelines and GitHub Actions, this chapter provides the reader a lot of real-life examples to reuse in their own environmentCHAPTER 7: EFFICIENTLY HANDLING BLAMELESS POST-MORTEMSPost-Mortems are the way to look back at what caused the outage, and describe any lessons learned for the future, helping in avoiding a similar outage in the future, or assist in quickly fixing an identical incident. Blameless is where the focus is on finding the root-cause of the problem, without pinpointing any individual or team as being the victim. This chapter describes how an open culture around post-mortems dramatically helps in optimizing SRE and the overall company culture around managing and running IT systems and application workloads.CHAPTER 8: MONITORING AS THE KEY TO KNOWLEDGEBesides the automated deployments, monitoring is the 2nd big technical topic in any SRE scenario. You can’t manage what you don’t know. This chapter provides an overview of Azure Monitor and Log Analytics, which forms the foundation of monitoring Azure and Hybrid-running workloads. Starting from metrics for the different Azure services touched on in earlier chapters, this chapter also covers how to export logs to 3rd party solutions such as Splunk or integrating dashboarding tools like Grafana
