Certified Ethical Hacker (CEH v10) — Question 111

How can rainbow tables be defeated?

Answer options

• A. Password salting
• B. Use of non-dictionary words
• C. All uppercase character passwords
• D. Lockout accounts under brute force password cracking attempts

Correct answer: A

Explanation

The correct answer is A, as password salting adds unique data to each password before hashing, making rainbow tables ineffective. Options B and C may enhance password security but do not specifically address the vulnerabilities of rainbow tables. Option D is related to brute force attacks but does not prevent the use of rainbow tables.
