Hackers can do an enormous amount of
damage if they break into a computer system.
For some people, the challenge of breaking the codes is irresistible and so precautions have to be taken.
Stand-alone computers are usually safe as there is no connection for the hackers to break into. Computers which form part of networks or those with external links, such as attached modems, are in danger from hackers.
Many hackers often don't intend to cause damage or steal data, they just enjoy the challenge of breaking into a system. However, in some instances the hacker's purpose could be to commit fraud, to steal valuable data or to damage or delete the data in order to harm the company.
