The Internet is not synonymous with World Wide Web. The Internet is a massive
network of networks, a networking infrastructure. It connects millions of
computers together globally, forming a network in which any computer can
communicate with any other computer as long as they are both connected to
the Internet.
History of Internet
The history of the Internet begins with the development of electronic computers
in the 1950s. Initial concepts of packet networking originated in several computer
science laboratories in the United States, United Kingdom, and France….
Commercial Internet service providers (ISPs) began to emerge in the very late
1980s.

is a branch of compute security specifically related to the Internet, often involving browser
security but also network security on a more general level as it applies to other applications
or operating systems on a whole. Its objective is to establish rules and measures to use against
attacks over the Internet. The Internet represents an insecure channel for exchanging information
leading to a high risk of intrusion or fraud, such as phishing. Different methods have been used to
protect the transfer of data, including encryption and from-the-ground-up engineering
Threats

 Denial-of-service attacks
 Phishing
 Application vulnerabilities
Solution
