The Definitive Guide to PCI DSS Version 4
This book is your go-to reference on how to achieve PCI compliance. With more than 400 PCI requirements, the updated PCI Data Security Standard (PCI DSS) v4.0 does not detail the specific documentation that a PCI auditor—known as a Qualified Security Assessor (QSA)—needs to know. This book is the first reference to detail the specific documentation needed for every PCI requirement. The authors provide real-world examples of complying with the 12 main PCI requirements and clarify many of the gray areas within the PCI DSS.Any merchant or service provider that stores, processes, or transmits credit card data must comply with the PCI Data Security Standard. PCI DSS 1.0 was first published in 2004, yet many of those tasked with PCI compliance still encounter difficulties when trying to make sense of it. PCI DSS version 4 was published in March 2022, and at 360 pages, it has numerous additional requirements, leaving many people struggling to know what they need to do to comply.PCI DSS v4.0 has a transition period in which PCI DSS version 3.2.1 will remain active for two years from the v4.0 publication date. Although the transition period ends on March 31, 2024, and may seem far away, those tasked with PCI compliance will need every bit of the time to acquaint themselves with the many news updates, templates, forms, and more, that PCI v4.0 brings to their world.WHAT YOU’LL LEARN* Know what it takes to be PCI compliant* Understand and implement what is in the PCI DSS* Get rid of cardholder data* Everything you need to know about segmenting your cardholder data network* Know what documentation is needed for your PCI compliance efforts* Leverage real-world experience to assist PCI compliance workWHO THIS BOOK IS FORCompliance managers and those tasked with PCI compliance, information security managers, internal auditors, chief security officers, chief technology officers, and chief information officers.

Vom Ding an sich zum Internet der Dinge
Seit Beginn dessen, was man Philosophie nennt – also dem Zeitalter der Vorsokratiker – haben große Geister sich bemüht, den Dualismus Geist-Materie zu überwinden und Erkenntnis auf eine einzige, eindeutige Quelle zurück zu führen – dem Ding-an-sich. Diese Entwicklung wird in diesem Buch nachverfolgt – bis hin zu den modernen Instrumenten der Datenhaltung und der künstlichen Intelligenz. Im Internet of Things schließlich werden Informationen und Objekte wieder zu einer einzigen Entität verschmolzen. Liegt da vielleicht die Lösung nach der Suche des Ding-an-sich?WOLFGANG OSTERHAGE ist Diplom-Ingenieur mit Promotionen in Physik und Informationstechnologie und war lange Jahre als Berater in internationalen Organisationen, der freien Wirtschaft und als Dozent an verschiedenen Institutionen tätig.

Roll away the boring stuff!
Too often, users need to perform the same tasks again and again. It's not only boring, it takes up the time that could be used differently! In this book, you will learn how to do less typing, how Excel can insert formattings and calculations for you, how to establish best relationships between cells, how to adjust table data, that is provided in a less than perfect way and how to arrange the Excel window in a way to find desired features quicker.Ina Koys is an experienced instructor for Microsoft Office. Many questions are frequently asked in trainings, but seldom covered in books. Now she answers some of them in her originally German "short & spicy" series. A little accent will add to the fun :-)
New ways to go!
You’re working with Excel since long, but would like some fresh inspiration? You had an Excel training 15 years ago and wonder what all these new buttons could do for you? Then, this book is for you! We’ll be looking at all new topics from Excel 2007 onwards: Matrix operations, Flash Fill, Conditional Formatting, Sparklines, new formulas and much more. All explained using clear examples, suitable for normal users and insiders.Ina Koys is an experienced instructor for Microsoft Office.

How to get Instant Overview
Often, Excel is used to evaluate given data. Which values are critical? Can I see at a glance what the development was like? Can I highlight a whole row if one column has important content? Or ask for the content of two cells, simultaneously? How do I get overview in a thick workbook? How do I get a clear and telling chart? Is there anything as clear, but not as large as a diagram? Can I ask Excel in natural language without any formula? All these questions are answered here.Ina Koys is an experienced instructor for Microsoft Office.
