This book provides an overview of the complex discussions on cyberspace, as well as a detailed analysis of the role of the Cyber and Information Space, which corresponds with current state-of-the-art perspectives. By combining neoliberal economic practices with the oligarchic ownership of global communication platforms, opinion-forming giants have firmly established themselves in the digital space in only a few decades. They largely dictate the global public experience and manipulate what the public hears and sees based on their own rules, or algorithms. This new asymmetry of informational power must be acknowledged as a strategic risk. Cybersecurity in the 21st century cannot be separated from questions of public discourse, digital literacy, algorithmic transparency, and platform accountability. Cybersecurity is no longer just an issue of national defence or risk management, it is a defining question of sovereignty, democracy, and societal cohesion.
