Computer Security - What Exactly Is It?

by: Ciontescu Molie

Although the term 'computer security' is used a lot, the content of a computer is actually vulnerable to only a few risks unless the computer is connected to others on a network. As the use of computer networks (especially the Internet) has increased dramatically during the past few years, the term computer security is now used to describe issues referring to the networked use of computers and their resources. The major technical areas of computer security are confidentiality, integrity and authentication/availability. - Confidentiality, also known as secrecy or privacy, means that the information you own cannot be accessed by unauthorized parties. Breaches of confidentiality range from the embarrassing to the disastrous. - Integrity means that your information is protected against unauthorized changes that are undetectable to authorized users. The integrity of databases and other resources are usually compromised through hacking. - Authentication means that an user is who he claims to be. - Availability means that the resources are accessible by authorized parties. Examples of availability attacks are the 'denial of service' attacks. Other important things that the computer security professionals are concerned about are access control and nonrepudiation. Access control refer not only to the fact that users can only access the resources and services they are entitled to, but also to the fact that they can't be denied to access the resources they legitimately expect. Nonrepudiation means that a person who sends a message cannot deny he sent it and vice versa. In addition to these technical aspects, the concept of computer security is very large. Computer security's roots are drawn from disciplines like ethics and risk analysis and the major topics that are concerning it are computer crime (tries to prevent, detect and remedy attacks) and identity/anonymity in cyberspace. Although confidentiality, integrity and authenticity are the most important things when it comes to computer security in general, for everyday internet users, privacy is the most important one, because many people think that they have nothing to hide or the information they give doesn't seem sensitive when they register with an internet service/site. But remember that, on the internet, information is very easily shared among companies and small pieces of related information from different sources can be linked together to form something alot more complex about a person. Because of this, nowadays, the ability to maintain control over what information is collected about them, who may use it and how it can be used is extremely important.

Computers Are Not Scary

by: Lucas Gentry

Do you remember when you were a kid, and saw your first automobile? To the older crowd, the answer might be yes. To them, the first automobile was most-likely an object of wonder. It wasn't necessarily a thing to be feared, just an unknown. It was something that you had heard of, but hadn't had any experience with it. It wasn't scary. To most everyone else, you don't remember your first time you saw an automobile, because they've just always been around. You aren't scared of them because you are familiar with them. The youngest generation of youth feel the same way about computers. Many of you may remember the first time you saw a computer. It was a strange thing that you weren't familiar with. To some of you, it was exciting. To others, it wasn't. But somewhere along the line, you decided that using a computer was something that only younger (or more "gifted") people should do. We're past the age when cars are for only the most wealthy. Now, everyone has a car. In previous days, it was perfectly fine to walk everywhere. Some still do that, but most have learned to drive. In these days, there are still some who can "get around" just fine without the use of a computer, but most people use them multiple times in a week. In the same way, however, that most people see cars, the younger generations see computers. Computers are not something to fear. They're only something that you're not familiar with. That doesn't make them bad. And it doesn't make YOU bad. So in the same way you have gotten used to cars, go ahead and have some fun with computers. Play around. You won't break it, just like you didn't break your car the first time you got in it. Go for it! Have Fun!

Decide On A PC Monitor Before You Buy Your New Computer Equipment

by: Bonnie Archer

Before you buy your new computer equipment you will want to decide on a PC monitor. After all you will be staring at it for the next few years! You will need to decide on the image quality, resolution, size, and type Your new should have enough screen space for what you will be doing. The viewable size is about an inch smaller that the advertised tube size on CRTs. The best size for most people is 17-19 inch. Either of these sizes should be plenty for most computer equipment needs. An LCD screen is the full size it says so it really takes up a lot less space than the CRT, inch for inch. Would A LCD or CRT PC Monitor Fit Your Style of Computer Equipment? Is an LCD PC monitor for you? For most computer users a 17 inch LCD is the optimal desktop pc monitor. A 15 inch is cheaper but will seem quite small if your current computer equipment as a 17 inch CRT. 17 inch will be most comfortable in size and price. The price is much higher when you get to an 18 to 19 inch PC monitor. Maybe a CRT PC monitor is for you? The 19 inch flat screen is great, the price is about the same as a conventional but the picture quality is much greater. Also, it will take up much less desk space then the conventional PC monitor. Important Note From PCworld Magazine: When you are finished using your current computer equipment never, ever send your old PC monitor to the dump. Recycle it instead. It's not only good for the environment, but it's also a legal requirement in some states that will not accept PC monitors in regular municipal landfills. CRTs contain four to six pounds of lead plus other toxic materials that leach into the soil and water if not properly disposed. Check with the vendor or your local government to find recyclers in your area that can handle CRTs. Bonnie Archer A1-computers.net word count 347 About the author: B.
