Ethical hacking involves legally accessing computer systems and networks to test security and find vulnerabilities. It helps identify weaknesses that criminals could exploit. There are different types of hackers defined by their intentions and knowledge - white hat hackers help companies, while black hat hackers intend harm. Ethical hacking is important as it allows issues to be addressed before real attackers can cause damage. Common attacks include brute force, buffer overflows, and denial of service. Companies should implement security measures like strong passwords, antivirus software, and logging out of accounts to protect themselves from hacking.

3. INTRODUCTIONINTRODUCTION
The explosive growth of the Internet has brought many good things :
electronic commerce, easy access to vast stores of reference material,
collaborative computing, e-mail, and new avenues for advertising and
information distribution , to name a few. As with most technological
advances , there is also a dark side : criminal hackers. Governments,
companies, and private citizens around the world are anxious to be a part of
this revolution, but they are afraid that some hacker will break into their
Web server and replace their logo with pornography, read their e-mail, steal
their credit card number from an on-line shopping site, or implant software
that will secretly transmit their organization’s secrets to the open Internet.
With these concerns and others, the ethical hacker can help.
