White Hat

A white hat is the hero or good guy, especially in computing slang, where it refers to an ethical hacker who focuses on securing and protecting IT systems.

White Hat Hackers, also known as Ethical Hackers, are Computer Security experts, who specialize in penetration testing, and other testing methodologies, to ensure that a company's information systems are secure. Such people are employed by companies where these professionals are sometimes called sneakers.[citation needed] Groups of these people are often called tiger teams[2] or red teams. These Security experts may utilise a variety of methods to carry out their tests, including social engineering tactics, use of Hacking tools, and attempts to evade security to gain entry into secured areas.
