📢 Introduction: Why Networking & Cybersecurity Matter More Than Ever

In today’s interconnected world, network security is no longer optional—it’s essential. 🚨 Cyberattacks cost businesses and governments billions of dollars each year, with breaches exposing millions of personal records and disrupting critical infrastructure. In 2023 alone, cybercrime damages were estimated to surpass $8 trillion globally, and experts predict this number will continue rising.

🔎 Recent Examples:

• The Colonial Pipeline ransomware attack (2021) disrupted fuel supplies across the U.S., costing $4.4 million in ransom and affecting millions of consumers.
• In 2023, MGM Resorts suffered a major cyberattack, leading to hotel system shutdowns, financial losses, and customer data breaches.
• Even hospitals and emergency services have been targeted, showing that network vulnerabilities can have life-or-death consequences.

💻 How Do Routers, Switches & Hubs Play a Role?
Routers, switches, and hubs control how data flows within networks—and misconfigurations or weak security can create major vulnerabilities. A hacked router can expose an entire organization to cyber threats, while a well-configured network can act as the first line of defense.
