Network Security

There are those who believe that the security issues facing home users are greatly exaggerated, and that the only entities which need to be concerned about desktop and network security are businesses which have critical data on their machines. And many think that only broadband users or folks with high-speed connections need to be concerned.Computers are used for variety of purposes which also include our daily personal works. Purpose could be for bank and investment or it could be placing your orders for shopping or food. We also use computers for the purpose of communication. You must be seeking privacy in your work and really don’t want any intruders which might also steal your data. No one would like stranger take over your computer and sending forged mails and monitoring information stored on your computer. We do not want to be the victims of data theft or ID theft, demanding computer security.
Networking is the manner in which two computerized devices communicate. Understanding how they communicate (since the internet uses TCP/IP for data transfers with packet acknowledgement and UDP/IP for streaming data, like video, without packet acknowledgement) will ensure that you design, configure and/or operate the computerized device optimally and when it is not optimal, know how to address that.
Networking, the alternate definition, is a new manner of engaging socially using computer devices and computer networks (networking is a term used as a synonym to “circle of contacts/friends” and how you manage both contacts and friends to be either a happy individual, have a thriving business or both), it is just recently that social Web sites (Facebook, Google+, Friendster, MySpace) have added a computer dimension to it. Knowing how to leverage these sites and using them wisely (this last point eludes, it seems, most people on those sites) will help you be more social and derives more benefits of such a thing.
A. The first line of defense for your Wi-Fi network is encryption, which encodes the data transmitted between your PC and your wireless router. Unfortunately, most routers ship with encryption turned off, and many users don’t turn it on, leaving themselves completely exposed. If you haven’t already, enable your router’s encryption, and use the strongest form supported by your network.
Internet Security suites usually include an antivirus application as well as firewall, anti malware, anti spyware, and email protection programs. It is better than standalone antivirus, but more costly.Network security is a complicated subject, historically only tackled by well-trained and experienced experts.
