CompTIA Security+ (SY0-501) — Question 327

In terms of encrypting data, which of the following is BEST described as a way to safeguard password data by adding random data to it in storage?

Answer options

• A. Using salt
• B. Using hash algorithms
• C. Implementing elliptical curve
• D. Implementing PKI

Correct answer: A

Explanation

Using salt is the best method for safeguarding password data because it adds random data to the password before hashing, making it more resistant to attacks like rainbow tables. The other options, such as hash algorithms and PKI, are important for data security but do not specifically address the addition of random data to passwords in storage.
