What Does Ethical Hacker Mean?
An ethical hacker is an individual hired to hack into a system to identify and repair potential vulnerabilities, effectively preventing exploitation by malicious hackers. They are security experts that specialize in the penetration testing (pen-testing) of computer and software systems for the purpose of evaluating, strengthening and improving security.
An ethical hacker is also known as a white hat hacker, red team, tiger team or sneaker.
Techopedia Explains Ethical Hacker
Generally, a software or hardware vendor achieves greater profitability by hiring ethical hackers, versus being subjected to other types of vulnerabilities and exploitations.
Ethical hackers evaluate systems using a number of methods, some of which include:
- Denial of Service (DoS) attacks: These are usually applied by flooding a system with requests, rendering it unable to handle additional requests, which halts service to other users or results in system overflow and/or shutdown.
- Social Engineering tactics: Akin to simple fraud, these include any act that manipulates a user into divulging information or performing specific actions.
- Security scanners: Used to discover vulnerabilities, security scanners are exploitation tools designed to discover vunerabilities in networks.
