Network Security 101Written by Robert Flanglin
As more people are logging onto Internet everyday, Network Security becomes a larger issue. In United States, identity theft and computer fraud are among fastest rising crimes. It is important to protect your network and ensure safety of all computers and users in that network.What is a Network? In order to fully understand network security, one must first understand what exactly a network is. A network is a group of computers that are connected. Computers can be connected in a variety of ways. Some of these ways include a USB port, phone line connection, Ethernet connection, or a wireless connection. The Internet is basically a network of networks. An Internet Service Provider (ISP) is also a network. When a computer connects to internet, it joins ISP’s network which is joined with a variety of other networks, which are joined with even more networks, and so on. These networks all encompass Internet. The vast amount of computers on Internet, and number of ISPs and large networks makes network security a must. Common Network Security Breeches Hackers often try to hack into vulnerable networks. Hackers use a variety of different attacks to cripple a network. Whether you have a home network or a LAN, it is important to know how hackers will attack a network. One common way for a hacker to wreak havoc is to achieve access to things that ordinary users shouldn’t have access to. In any network, administrators have ability to make certain parts of network “unauthorized access.” If a hacker is able to gain access to a protected area of network, he or she can possibly affect all of computers on network. Some hackers attempt to break into certain networks and release viruses that affect all of computers in network. Some hackers can also view information that they are not supposed to see.

But it can be simplified into layman's terms. On same note, you can’t take it too lightly, because there is a lot to think about. Believe me, purchase of a new computer can affect you sanity for next 2-5 years. I read an article that stated most Americans ask: “What do I want?” Instead of: “What do I need?” when they go shopping. Now, if money is no object, stop reading this and return to your carefree life of Lamborghinis, Beluga, and chilled three olive Martinis. Otherwise this may help you in deciding on your next purchase. Can I go no frills? ------------ Yes, there are some good no name brands that will work just as well. However, (Personally) I prefer brand name PC’s to no frills isle. The $50-$75 that you save for going cheaper way may cause you headaches when a warranty issue comes around. Does size matter? ------------ I did a quick survey and contrary to what we would like to think, size does matter. I mean it’s pretty simple when you think about it, larger it is, more information you can store on it. (What did you think I was talking about; get your mind out of gutter) Seriously, if you write essays/proposals for school or work, play a lot of games, or have tons of music that you would like to store, you’ll need to make sure you get a hard drive with practical size. (80-120GB should be fine for now, if you need more space in a year or so you can look at an external USB or Firewire HDD) How fast is fast? ------------ In order to answer this you will have to ask yourself one question. What am I going to do with my new PC? If you are using it for checking emails, writing letters and surfing web, save yourself some money and go with Celeron processor and standard RAM package. If you are going to play games, develop graphics and use your PC as a TV/stereo, you’ll need to go with Pentium or equivalent processor and boost your RAM to 1GB or what ever you can afford. (Remember, more RAM (memory) is one of best ways to speed up your PC)
