hands-on guide to LANs
Area Networks: Management, Design and Security aims
to give a practical introduction into the running and
design of LANs and a look at the technology behind it.
The content explores the hardware as well as the software
components and running methods with practical examples.
It uses the examples of Novell NetWare, Linux, and Windows
2000-based systems since they are most commonly used
The book begins with some background material about
data communication, which can be avoided by advanced
users. It moves on to the client and server architecture
that makes up a typical LAN. The server's construction
and specifications are particularly discussed. Structured
cabling and switch technology are also talked about
in reasonable detail.
applications for LANs talks about OS functions and security-related
administration. The philosophy of running a LAN setup
covers the different ways in which a system administrator
can do his/her job. The book ends with a look at Intranets.
It talks about how an Intranet can help an enterprise
improve communication within itself.
The book is great for someone who wants to get back
to the basics and take a retrospective look at the nitty-gritties

seems that along with the approach of Diwali and Halloween,
the activities of the evil-doers of the connected world
have intensified in the last few weeks.
Researchers from the University of California at San
Diego said online vandals intent on lashing out at companies
and rivals stage DoS attacks more than 4,000 times every
week. And in the last three weeks, more than 4000 attacks
were spotted in each week. Thankfully, more than half
of the attacks lasted less than 10 minutes. The targets
were Amazon.com, America Online, Microsoft's Hotmail,
a large number of individual users, and small businesses.
In another incident, the root servers which manage the
Internet's DNS were subject to a brutal DoS attack this
month. A flood of data barraged the servers in an attempt
to slow down server performance, but the simple nature
of the attack, and the system's resiliency, allowed
administrators to quickly block the data stream. According
to security experts, a more sophisticated attack could
have disrupted the root servers long enough to impair
And speaking of spooky happenings, do you know the number
of DNS servers that were attacked? The number is 13.
To spook you further here's a list of the top ten viruses
that attacked servers in September 2002.
