Explanation

Password Salting Explanation

Option B is correct because password salting is the technique of adding random extra characters (the "salt") to a password before hashing it, which makes rainbow table attacks ineffective since the precomputed hash values in a rainbow table won't match the salted hash stored in the system.

Why the distractors are wrong:

  • A (Password key hashing) is not a standard security term/countermeasure and does not describe the process of adding extra characters to a password
  • C (Password hashing) alone simply converts a password to a fixed-length string, but without added characters, rainbow tables can still crack common hashed passwords since the hashes are precomputed
  • D (Account lockout) is a brute-force countermeasure that locks an account after failed attempts - it has no relevance to rainbow tables, which work offline against stolen password databases

Memory Tip

Think of "salting your food" - just as adding salt changes the flavor of a dish in a unique way, adding a salt value changes the hash of a password uniquely, making it unrecognizable to a rainbow table. Extra characters added = Salt!
