A Certified Ethical Hacker (CEH) is trained with the strategies, tactics, technologies, tools, and motivations of cybercriminals. 

Certification process

An aspirant must qualify for the CEH (Certified Ethical Hacker) exam to be a certified hacker. The overall process includes:

  • The Electronic Commerce Council (EC-Council) offers a CEH training program with over 20 modules to cover most cyber threats
  • The EC-Council offers an online CEH handbook, and an exam blueprint with a range of practice questions
  • Many organizations offer CEH exam preparatory courses for the professionals
  • Candidates are required to go for practice tests online held by EC-Council 

A candidate must complete the EC-Council training program and pass an exam with 125 multiple-choice questions, with a four-hour limit. The successful students are awarded a CEH (Practical) certification, which is recognized globally, to help develop a senior ethical hacking career.

 All the passes outs are required to be recertified after every three years to maintain CEH status and help them keep updated.
