Connection to the Internet is accomplished in several different ways. A user may obtain an account on a host connected to the Internet and access Internet services by means of that host. Finally, an organization may connect its own network to the Internet and become a network on the Internet referred to as an Internet subnet.
Internet users have different roles as a result of their type of connection.
End users are those users who have an account on an Internet host. Host administrators are those users who have PCs or workstations which are Internet hosts. Network administrators are those users who manage an Internet subnet. Network administrators are often also host administrators, and both network administrators and host administrators are end users as well. While connection to the Internet provides many benefits for both individuals and organizations, several security problems can occur with Internet connection and use.
