“The Internet has become an integral part of daily life. Unfortunately, while many people have come to rely on it, most have little or no understanding of how the Internet works. This can pose serious problems, particularly as issues around information security become more common and more serious.
“This article will set out to explain to readers who have little or no technical background how the Internet works. It is hoped that this will provide those readers with a good fundamental knowledge of the principles and terminology of the Internet, so that they can begin to protect themselves against the variety of security threats that exist on the Net.”

“As broadband Internet access has become increasingly popular, and many people have invested in multiple computers in their household, a home LAN is on its way to becoming the norm. Sharing broadband internet access through a LAN can save you a lot in the cost of a modem and additional IP address for each PC connected. But how do we go about setting up a LAN, and what about sharing our broadband Internet access?”

Anchor Link Internet Protocols
Information Only Last Reviewed: 2009-03-19
“The Internet protocols are the world’s most popular open-system (nonproprietary) protocol suite because they can be used to communicate across any set of interconnected networks and are equally well suited for LAN and WAN communications. The Internet protocols consist of a suite of communication protocols, of which the two best known are the Transmission Control Protocol (TCP) and the Internet Protocol (IP). The Internet protocol suite not only includes lower-layer protocols (such as TCP and IP), but it also specifies common applications such as electronic mail, terminal emulation, and file transfer. This chapter provides a broad introduction to specifications that comprise the Internet protocols. Discussions include IP addressing and key upper-layer protocols used in the Internet. Specific routing protocols are addressed individually in Part 6, Routing Protocols.”

“These days, the vast majority of administrators go to great lengths to protect the files on their network. Typically, elaborate firewalls are used to keep outsiders away from file servers. The files residing on those servers often lie behind an intricate permissions scheme and are often encrypted. Complex auditing mechanisms might even monitor access to files. The point is that in this day and age, most administrators take security very seriously. What you might not realize though is that all of this security can be easily undone through the simple action of a user accessing a file through legitimate means. In this article, I will show you how this is possible and what you can do to fight back.”
