Ethical hacking, takes place with the explicit permission of the company whose system is being attacked. Ethical hacking often performed by white hats or skilled computer experts, is the use of programming skills to determine vulnerabilities in computer systems. While the non-ethical hacker or black hat exploits these vulnerabilities for mischief, personal gain or other reasons, the ethical hacker
evaluates them, points them out, and may suggest changes to systems that make them less likely to be penetrated by black hats. But ethical hacking is much different. The work of ethical hacking is still considered hacking because it uses knowledge of computer systems in an attempt to in some way penetrate them or crash them. This work is ethical because it is performed to increase the safety of the computer systems. Need for Ethical Hacking in the market:
One of the first examples of ethical hackers at work was in the 1970s, when the United States government used groups of experts called red teams to hack its own computer systems. According to Ed Skoudis, Vice President of Security Strategy for Predictive Systems' Global Integrity consulting practice, ethical hacking has continued to grow in an otherwise lackluster IT industry, and is becoming increasingly common outside the government and technology sectors where it began. Many large companies, such as IBM, maintain employee teams of ethical hackers. Why Ethical Hacking is must? A good knowledge of ethical hacking helps you to build a successful career in many big and small IT firms or other corporate firms. The future prospect of ethical hackers is bright as more and more companies are taking all possible steps to ensure security of various data and networks.
