Computer Security

This book is a collection of my articles originally published in the blogs Interrupt by Memfault and PlatformIO, with some additional edits and enhancements.   A unique feature of this book is the extensive use of GIF animations and videos to visually demonstrate key concepts and processes. However, since not all EPUB readers support GIF and video playback, each animation and video is accompanied by a link to an external resource. Readers can follow these links to view the corresponding content and enhance their understanding. Repo with all GIF animation: https://github.com/Zamuhrishka/diving-into-jtag-book-animations
