Using many practical examples and notes, the book offers an easy-to-understand introduction to technical and organizational data security. It provides an insight into the technical knowledge that is mandatory for data protection officers. Data security is an inseparable part of data protection, which is becoming more and more important in our society. It can only be implemented effectively if there is an understanding of technical interrelationships and threats. Data security covers much more information than just personal data. It secures all data and thus the continued existence of companies and organizations.

This book is a translation of the original German 2 nd edition Datensicherheit by Thomas H. Lenhard, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2020. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.

Offers an easy to understand introduction Shows numerous practical examples that can be implemented directly in companies and organizations Presents technical correlations and hazards in relation to the implementation of data security
