Description

This course explains what the Internet is and how the Internet works. An overview of the many risks involved in connecting to the Internet is given. The course explains how to use so-called "firewalls" to safely connect to the Internet.
A basic security purpose of a firewall is to act as a required access point between the internal and the external networks. Such a configuration will require that the current application environment be reconfigured to make it transparent to the end users. Two of these major applications, name services (DNS) and e-mail (Sendmail), and their configuration considerations constitute a major focus of this course. Cryptography is considered vital to support electronic commerce on the Internet. An overview of basic cryptographic concepts is given.

Audience

This course is intended for systems engineers and systems managers who will be responsible for their company's secure connection to the Internet.
