The job of a ethical hacker is to perform hacking to protect from crackers (unethical hackers). Some of these hacking books for beginners are about basic concepts, whereas other books focus on more advanced hacking techniques that experienced hacker can use.
Hacking is considered to be a two-way tool wherein a computer system is penetrated either to make it more secure or to create mischief. Ethical hacking is defined as making use of programming skills, so as to penetrate a computer system, and determine its vulnerabilities. The ethical hackers are skilled computer experts, often called as the "white hats". As against non-ethical hackers or "black hats" that penetrate into a computer system and exploit it for their own personal gains or mischief, the “white hats” evaluate and point out the vulnerabilities of system software, and suggest system changes to make it less penetrable.
With an increase in the use of Internet, concerns regarding its security have also grown manifold. This is particularly true in the case of highly confidential data. There have been past instances where the sites owned by even the most influential organizations have been hacked. This calls for designing systems which are impenetrable or an identification of the weaknesses of an existing system. Due to this reason, there is now a high demand for computer experts who can conduct ethical hacking operations.
Most of the organizations seek to acquire ethical hacking services from full-time employees or consultants so as to ensure security of their systems and information, thus making ethical hacking a highly lucrative profession.
