Computer access a shell onanother machine so that
Computer Hacker The meaning of Hacker is one who accesses a computer which issupposably not able to be accessed to non authorised people of the community. Hackersmay use any type of system to access this information depending on what they intend ondoing in the system. Methods Hackers may use a variety of ways to hack into a system.
First if the hacker is experienced and smart the hacker will use telnet to access a shell onanother machine so that the risk of getting caught is lower than doing it using their ownsystem. Ways in which the hacker will break into the system are: 1) Guess/crackingpasswords. This is where the hacker takes guesses at the password or has a crackprogram to crack the password protecting the system. 2) Finding back doors is anotherway in which the hacker may get access to the system. This is where the hacker tries tofind flaws in the system they are trying to enter. 3) One other way in which a hacker maytry to get into a system is by using a program called a WORM. This program is speciallyprogrammed to suit the need of the user.
This programme continually tries to connect toa machine at over 100 times a second until eventually the system lets in and the wormexecutes its program. The program could be anything from getting password files todeleting files depending on what it has been programmed to do. Protection The only waythat you or a company can stop a Hacker is by not having your computer connected tothe net. This is the only sure fire way in which you can stop a hacker entering yoursystem. This is mainly because hackers use a phone line to access the system. If it ispossible for one person to access the system then it is possible for a hacker to gainaccess to the system.
One of the main problems is that major companies need to benetworked and accessible over the net so that employees can do overdue work or sothat people can look up things on that company. Also major companies network theiroffices so that they can access data from different positions. One way which is used totry to prevent hackers gaining access is a program used by companies called a Firewall.A Firewall is a program which stops other connections from different servers to thefirewall server. This is very effective in stopping hackers entering the system. Tho this isnot a fool proof way of stopping hackers as it can be broken and hackers can get in.
Thothis is a very good way of protecting your system on the InterNet. Major Hacks Some ofthe major hacks that have been committed have been done by young teens agedbetween 14 and 18.

In conclusion it can be saidthat hackers are sophisticated and very talented when it comes to the use of a computer.
Hacking is a process of learning not following any manual. Hackers learn as they go anduse a method of trial and error. Most people who say they are hackers most of the timeare not. Real hackers do not delete or destroy any information on the system they hack.
Hackers hack because they love the thrill of getting into a system that is supposablyunable to be entered. Overall hackers are smart and cause little damage to the systemthey enter. So hackers are not really terrorists in a way they help companies find outBibliography:
