Network security is becoming increasingly
important to personal computer users, businesses, and
the military. Security became a major concern with the
advent of the internet, and understanding the history of
security allows a better understanding of the emergence
of security technology. Many security threats can occur
due to the structure of the internet. If the internet's
architecture is changed, it can reduce the number of
possible attacks that can be sent across the network.
Knowing the attack methods enables us to respond with
adequate security. Many businesses use firewalls and
encryption mechanisms to protect themselves from the
internet. To stay connected to the internet, businesses
create an "intranet."
