Firewalls monitor incoming and outgoing network traffic to prevent viruses based on security rules, with the first firewall created in 1980. Cyberbullying is bullying online, especially among teenagers on social media, with a recent dangerous trend being the "Blue Whale Challenge." The black market illegally sells organs, children, drugs, weapons, and other illicit goods both online through secret websites and in real underground markets. Similarly, the dark web focuses on illegal online sales and activities, allowing people to hire assassins, test drugs on people, and access other dangerous or unlawful acts and materials only findable on the deep hidden internet.
