Implementing
Authentication
Aliases are shortcuts used to identify groups of hosts,
networks, or users. The use of aliases simplifies ser-
vice configuration.
User authentication allows the tracking of connections
based on name rather than IP address. With authenti-
cation, it does not matter which IP address is used or
from which machine a person chooses to work. To
gain access to Internet services (such as outgoing
HTTP or outgoing FTP), the user provides authenti-
cating data in the form of a username and password.
For the duration of the authentication, the session
name is tied to connections originating from the IP
address from which the individual authenticated. This
makes it possible to track not only the machines from
which connections are originating, but the user as
well.
