Detailed explanation-1: -A brute-force attack is a trial-and-error method used by application programs to decode login information and encryption keys to use them to gain unauthorized access to systems. Using brute force is an exhaustive effort rather than employing intellectual strategies.
Detailed explanation-2: -A brute-force attack is a trial-and-error method used to obtain information such as a user password or personal identification number (PIN). In a brute-force attack, automated software is used to generate a large number of consecutive guesses as to the value of the desired data.
Detailed explanation-3: -Brute-force attack definition: “An attack in which cybercriminals utilize trial-and-error tactics to decode passwords, personal identification numbers (PINs), and other forms of login data by leveraging automated software to test large quantities of possible combinations.”
Detailed explanation-4: -What four basic protections can cryptography support? Cryptography can support confidentiality, integrity, authentication, and nonrepudiation.
Detailed explanation-5: -Leaving the key unprotected So you need to encrypt your encryption key itself with another encryption key, typically called a Key Encryption Key (KEK), which you then need to store in an entirely different location.
