• Hacker generally is described as the word of person who has specialist skills in
the field of computer and information security. It is launched essentially on a set
of clever programmers who defies the different systems and try to storm, but
not necessarily to commit a crime, but their success in penetration is considered

programmer tested his abilities without knowing his real name or declaring
himself. But some of them are exploiting for criminal sabotage to clear
information and others are exploiting commercially for the purposes of
espionage and to steal some money.
• A lot of companies like Microsoft needs to protect their systems, and it found
that the best method is to set high salaries for hackers whose mission is to
attempt to penetrate the various systems and find places weaknesses, and
suggest ways for prevention from damage caused by computer hackers. In this

spoiler hacker. Despite both have the intelligence and spirit of
challenge and lack of fear of facing the unknown, but the cracker

networks or hotspots where they exploit a common data between users of
these networks and gaps in the connected devices to the network , that
will enable the hacker to penetrate.
8. How hacker penetrates sites:
• This is done through two phases:1) the collection of information; the
most important information are the target network address and
knowing the operating system on that goals and scripts System to
examine them if it had gaps software and these gaps allow a hacker
does several things forbidden. 2)The attack phase; it is exploiting the
gaps . These hackers enter the control panel, apply commands on the
server or raising malicious files.
