A CEH (Certified Ethical Hacker) is a professional who typically works within a Red Team environment. A Certified Ethical Hacker’s focus must be on attacking systems and accessing applications, networks, databases, or other crucial data on the secured systems. In addition to recognizing attack strategies and exploiting creative attack vectors, a CEH can mimic the skills and creativity of malicious hackers. Unlike black hat hackers, certified ethical hackers approach systems with permission from their owners and maintain the confidentiality of their work. https://www.infosectrain.com/blog/domain-1-of-ceh-v11-information-security-and-ethical-hacking/
