Nach über acht Monaten intensiver Arbeit, unzähligen Tassen Schwarztee und Club-Mate-Flaschen war es heute so weit: Der Postbote stand vor der Tür und überreichte mir die allerersten Autorenexemplare meines ersten eigenen englischsprachigen Buches!

„Hacking Hardware: The Practical Guide to Penetration Testing and Prevention” ist nun offiziell bei Rheinwerk Publishing in den USA erschienen. Es physisch in den Händen zu halten, durch die frisch gedruckten Seiten zu blättern und das eigene Cover zu sehen, ist ein absoluter Meilenstein für mich.

How does this affect assurance and third-party risk management?
