Who Are We Protecting Systems From?
Who Are We Protecting Systems From?
In the previous chapter, we learned that cybersecurity exists to protect the digital world. But that raises an obvious question. Who are we protecting it from? Let's start with a simple thought. If nobody ever tried to break into computer systems... If nobody tried to steal data... If nobody disrupted online services... Would we even need cybersecurity? Probably not. Cybersecurity exists because there are people—and sometimes even organizations—constantly trying to exploit digital systems. But here's something important. Not every attacker is the same. Some are cybercriminals trying to make money by stealing bank details or demanding ransom. Some are insiders—employees or contractors who misuse the access they've already been given. Some are hacktivists, who attack organizations to promote a political or social cause. Some attacks are carried out by highly organized groups working across countries. And some are even backed by nation states, targeting critical infrastructure, governments, or strategic industries. The motivations are very different. Money. Espionage. Revenge. Politics. Curiosity. Competition. Even reputation. Understanding who the attackers are is only half the story. The other half is understanding why they attack. Because once you understand their motivations, you begin to understand how defenders think, how organizations prepare, and why cybersecurity is much more than just installing antivirus software. In cybersecurity, every defense starts with one simple question: Who might attack us, and what are they trying to achieve? That's the mindset you'll keep building throughout this journey.
