__________ is a technique used to help protect against attacks exposing the contents of the server where password information is stored.

Question

BlackTom AI · Accepted Answer

In this question, we’re asked to identify which technique is used to help protect against attacks that expose password contents on the server. 
Option a: 'password exposure' is not a named protective technique; it simply describes a potential risk—exposure of passwords—not a method for protecting them. Therefore this choice is incorrect.
Option b: 'host attack' refers to a type of attack targeting the hosting machine or its services, not a technique specifically for protecting password data in storage. It mislabels the protective approach, so it is not the right answer.
Option c: 'password cracking' is an attack method where an adversary attempts to recover passwords from hashes or stored data; it is the opposed action, not a protective technique. This option describes what attackers do, not how to defend against exposure, thus it is incorrect.
Option d: 'password hashing' is a fundamental security technique that protects passwords by converting them into fixed-length, usually irreversible representations before storage. Even if an attacker gains access to the password database, they would encounter hashed values rather than plaintext passwords, making this the protective measure described in the question. This option is correct.
