In this course, we cover the Internet and IP Security.

We'll start at the beginning of the story, understanding where the Internet came from and its fundamental principles of operation. Then we'll look at some details and improvements such as the Domain Name System, MIME, HTML and HTTP... which form “the Web”. We'll review how you can connect to the Web from a residence and from an enterprise or organization.

In the second part, we'll make a reasonably comprehensive overview of security in the IP world. We'll begin with a discussion of risk areas, vulnerabilities and measures. Then we'll examine several areas: computer security and malicious software like viruses and Trojan Horses and the measures to protect against these risks; network security and firewalls, public key and private key encryption, authentication, IPsec and VPNs.
