Certified Ethical Hacker (CEH v11) — Question 72

Ethical hacker Jane Doe is attempting to crack the password of the head of the IT department of ABC company. She is utilizing a rainbow table and notices upon entering a password that extra characters are added to the password after submitting.
What countermeasure is the company using to protect against rainbow tables?

Answer options

• A. Account lockout
• B. Password hashing
• C. Password key hashing
• D. Password salting

Correct answer: D

Explanation

The correct answer is D, Password salting, because it adds unique random data to each password before hashing, making rainbow tables ineffective. The other options, while useful for security, do not specifically address the issue of preventing attacks using rainbow tables.
