Seminar on Cisco Self-Defending Network

1.What are (Wireless / Computer) Networking?
In the world of computers, networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software.
If your business has more than one computer, chances are you could benefit from networking them. A local area network (LAN) connects your company's computers, allowing them to share and exchange a variety of information. While one computer can be useful on its own, several networked computers can be much more useful.
2.Introduction
Takeaway: The need for security is more important than ever in the business world. It's tough to decide how much to invest and what solutions to choose, but you must ensure that your network is reasonably secure. Here is an attempt made by us to explain the Cisco s Self-Defending Network.
If you're a cynical consumer, the Cisco Self-Defending Network (CSDN) solution probably begs the sarcastic question: "Yeah, right; the network that can just defend itself?" However, as Cisco typically makes quality products and solutions, I can't believe that the self-defending network concept is all bad; actually, it may even be the best solution on the market today.
3.What is Security?
While taking advantage of the possibility of defining strict rules of communication inside the network one must achieve a satisfactory level of security.
This involves a suitable distribution of roles among the systems. In this case hacking into one of the barriers won't compromise the whole network; such a hack will be limited to several devices or systems. For instance, breaking the first firewall will not cause a catastrophe. The hacker would only have access to the network cards of the web servers which have been placed outside and that have been protected as well as possible.
Why look at security solutions in the first place?
Since every business today depends on the Internet and LAN networks for some business critical function, the need for security is more important than ever. A company that does not have strong security can end up on the news as being hacked, their stock can plummet, and they can be out of business in no time. Once released, viruses and worms can hit businesses and consumers around the world in a matter of seconds or minutes.
However, you and your company don't have unlimited funds; you can't just put in every solution you discover. You have to weigh the level of investment in security with the level of risk that is perceived by your business. It's tough to decide how much to invest and what solutions to choose, but you must ensure that your network is reasonably secure.
