The need for complete network security has never been greater nor as well understood. Malicious users
threaten to steal, manipulate, and impede information. Numerous solutions address perimeter defense,
but the greatest threat of information theft and unauthorized access remains within the internal network
One point of concern is the relative ease of physical and logical access to a corporate network. Both
physical and logical access has been extended to enable a greater level of mobility, providing several
benefits to business operations and overall productivity.
The Cisco TelePresence System 3000 (CTS-3000) is designed for large group meetings, seating up to 12
participants around a virtual table. It consists of:
• Three 65” high definition plasma displays
• Three high definition cameras
• Three wide band microphones and speakers
• A lighting shroud integrated around a purpose built meeting room table
Customers must furnish their own chairs. A Cisco 7970G IP phone is used to launch, control, and end

The Open Systems Interconnection (OSI) model is a reference tool for understanding data communications between any two networked systems. It divides the communications processes into seven layers. Each layer both performs specific functions to support the layers above it and offers services to the layers below it. The
three lowest layers focus on passing traffic through the network to an end system. The top four layers come into play in the end system to complete the process.
Multiprotocol Label Switching
Multiprotocol Label Switching (MPLS) is a standards-approved technology for
speeding up network traffic flow and making it easier to manage. MPLS involves
setting up a specific path for a given sequence of packets, identified by a label put
in each packet, thus saving the time needed for a router to look up the address to
the next node to forward the packet to. MPLS is called multiprotocol because it
works with the Internet Protocol (IP), Asynchronous Transport Mode (ATM), and
frame relay network protocols....
This publication was developed to assist professionals preparing for Cisco Certified Internetwork
Expert (CCIE) candidacy, though it is a valuable resource for all internetworking professionals. It is
designed for use in conjunction with other Cisco manuals or as a standalone reference. You may find
it helpful to refer to the Cisco CCIE Fundamentals: Case Studies, which provides case studies and
examples of the network design strategies described in this book.
This chapter covers the actual process of sitting down and designing your OSPF network. The real process of putting the pen
to paper and the true process behind it is covered. It is this chapter's intention to take the mystery out of designing any type of
network. The concepts and steps discussed have universal application whether your network is BGP or OSPF; of course, the
latter is emphasized. Chapter 6, "Advanced OSPF Design Concepts," covered many of the commands necessary for
While I was writing this document a book "Hack Proofing Your Network" was released. I haven't been able to read it (dunno if its in print yet, and besides - everything takes a while to get to South Africa). I did however read the first chapter, as it is available to the public. In this chapter the author writes about different views on IT security - hackers, crackers, script kiddies and everything in between. I had some thoughts about this and decided that it was a good starting point for this document....
