The 21st Century is witnessing tremendous growth in the ICT and ICT-related sectors. Texts, pictures, and sounds have all become digitized. The migration from traditional communication to digitized forms has been fast-tracked by rapid globalization. The expanding technology comes with commendable social benefits just as it also creates avenues for internet-driven fraudulent activities. This is complicated by the increasing affordability of computer systems and increasing internet connectivity. The influx of digital and online services has thus increased the threat potential in business, government, and personal life. Most 21st-century transactions are done virtually, reinforcing the notion of a borderless world. The threats in cyberspace are by extension threats to sensitive national information assets. Cybersecurity breaches are beginning to have more impact on Nigeria’s national assets, including her institutions. This book discussed emerging ICT threats and Nigeria’s national security with a view to mitigating them. Written by a first-rate practitioner, it is hoped that the book will stimulate interest in further research on the subject matter. The book can be a reference point for ICT enthusiasts, students, and general interest readers. It is written in simple prose to make it readable by a wide audience, especially those who may be grappling with ICT-related threats in their private or official capacities.
