Network Security

Abstract:

Network security is a complicated, historically only tackled by well-trained and experienced experts. However, as more and more people become ``wired'', an increasing number of people need to understand the basics of security in a networked world. Whenever you share important and confidential information on network you must be careful about the security features like security of these resources. Network security is provided by various factors like security features of NOS, features of clients, physical cabling, security policies of management, administrating security etc. Internet security can be provided by filtering the packets going through router or by adding firewall.

Some history of networking is included, as well as an introduction to TCP/IP and internetworking. Consider risk management, network threats, firewalls, and more special-purpose secure networking devices.
This is not intended to be a ``frequently asked questions'' reference, nor is it a ``hands-on'' document describing how to accomplish specific functionality.

It is hoped that the reader will have a wider perspective on security in general, and better understand how to reduce and manage risk personally, at home, and in the workplace.
