What is a hacker one may ask? He doesnt wear a stocking mask over his face, nor does he break a window to get into your house. He doesnt hold a gun to your head, nor does he go through your personal possessions. Considering the situation, he recognized just the way a thief is recognized. But one strange thing about this thief is that youll never be able to see him, although you may not even realize right away that hes the one that robbed you. This thief is a computer hacker and he enters your home via your computer, which allows him to access your personal information. Amazing huh!!
Its very difficult to imagine that any person in todays technological oriented world could function without computers. Personal computers (Pcs) are linked to business computers and financial networks, and they are all are linked together via the Internet or other networks. As computer becomes more and more popular and important to our society, we can use computers everywhere and they are very useful and helpful to our daily lives. The extreme speeds and accuracy of computer has made people felt confident and reliable. Considering the population in the United States and throughout the world, there are more then a hundred millionth electronic messages that travel through cyberspace (internet) every day, and every piece of information is stored on a computer that is very vulnerable to attack. On any personal computers there are many important information or data are saved in the computer. Things such as: your diary, the financial statements of a company, or maybe something that is very secret which only the intelligence of the military or FBI department can read. A lot of important information can be found in the memory of computer. So, knowing the consequences people may begin to wonder and ask questions.
As older and newer companies are emerging, companies are becoming more aware and scared by the fact that their computers are prone to attack. Virus scanners (such as McAfee or Norton) are becoming requirements on every machine. When it comes to installing such programs and monitoring these virus scanners, it usually takes tremendous amount of time and tons of money for site licenses. Many server programs are coming equipped with a program called “netlog.” Which makes it a big advantage because this program not only monitors the computer use of the employees in a company on the network but it also monitors memory and file usage. A well-trained system administrator can usually be able to tell by the amounts of memory being used and the file usage if something is going on that should not be. When a virus is found, system administrators can usually pinpoint the user who put the virus into the network and investigate and determine whether or not if it was done intentionally.
Computer security can work in different ways with different methods. One option might be by locking it up or by password securing it. Another password security approach would be to have the computer user carry a digital screen that fits in your pocket. This digital screen will receive an encrypted message and will displays the numbers that change every few minutes. These numbers generate and make the password sequentially one after the next for the next few minutes in order to access the computer. This password security method is pretty much a new option to computer networks and much better then the previous password method. The reason so is because the passwords are stored in the computer and if a computer literate person was to access this information, then they mostly likely could get into a computer and enter it looking as if they were someone else, and at the same time they would have gotten someone elses password. Strange huh? But you have not seen anything yet. As time progresses when technology increasingly gets better there are more possibilities that you could never imagine such as a computer could use you hand, inner eye, or voiceprint as a security option. Right now these methods are not being used, but they will be shortly considering the fact that new technology is increasing rapidly. The best way to absolutely secure youre computer is to lock it but considering computer networks these days, they cannot be easily done unless you are dealing with a single computer.
To fully stop or prevent the hackers and other criminals, us people need to set up a well-known good security system in order to protect the data and information stored in the computer. One of the most important things is that we cannot allow these so called hackers and criminals to enter our computers. Not only does it mean that we need to design and construct a lock-to-lock system but we need to order up all our data and use identification system in order to verify the identity of someone seeking access to our
