Hacking is referred to as the illegal or legal practice of accessing data stored in any system by experts. These experts are termed as Hackers. Hackers have all the knowledge related to programming and its concepts. Mistakes made by programmers while developing or working on software are picked up by hackers to penetrate the security framework of the software.

Ethical hacking is conducted by hackers as well, but their intention behind hacking is not for malicious purposes. Their services are used to check and build on software security and thus help to develop the security system of a framework in a business or organization to prevent potential threats. Ethical hackers are referred to as White Hats, who end up providing protection from Black Hats (unethical hackers). Ethical hacking is adopted by almost every organization.
