ABSTRACT The common problem faced today by all the computer professionals around the world is the security of their computers. Now, why do they need security? What are they afraid of? The answer is very simple and well known, a “HACKER”. Hacking is a perennial concern for anyone who is into computer technology, either as a novice or as an expert. ‘Hacking’ and ‘Hackers’ are terms that generally tend to have a negative effect on people. Most people straightaway start associating ‘Hackers’ with computer criminals or people who cause harm to systems, release viruses etc .Now a days the media has been wrongly and outrageously referring to computer criminals as ‘Hackers’. We on the other hand do not go with the media and people who refer computer criminals as ‘Hackers’. We at the same time do not blame them for holding such a negative opinion. The fact is that one tends to accept what is being fed to him. Well ‘Hackers’ in reality are actually good, pleasant and extremely intelligent people, who by using their knowledge in a constructive manner help organizations to secure documents and company secrets, help the government to protect national documents of strategic importance and even sometimes help justice to meet its ends by ferreting out electronic

And that is why we insist that each and everybody who is somehow involved in computer technology need to know the hacking skills to protect his/her system from other hackers.

What people should understand here is that there is a lot of difference between a ‘Cracker’ and a ‘Hacker’. A cracker on the other hand breaks into other systems and does the unwanted things, which are illegal .The reason they do this because they want to get quick popularity. But they fail to understand that this popularity is negative. Besides, cyber crime has become punishable under law, and is considered a serious offence. In fact the most successful people in computer technology are well worse with hacking skills. SECURITY AND WINDOWS Now a days all the computers, which we use, are operated by windows OS.We also use Unix OS. Unix is considered to be the most secured OS. Whenever the two words ‘Security’ and ‘Windows’ come in a same sentence it would force any hacker (and naughty crackers too) to laugh because every hacker starts learning hacking skills from Windows only. Here’s one universal way that would work on all systems. To do this reboot the system and wait for the message: “Starting windows 9x”
