Which security standard forces a system to demand multiple independent proofs of identity—such as a password mixed with an instant mobile token—before permitting user access? MCQ with Answer and Explanation
Which security standard forces a system to demand multiple independent proofs of identity—such as a password mixed with an instant mobile token—before permitting user access?

Solution (By JKSSB Mock Tests)
MFA combines validation factors from distinct categories: something you know (password), something you have (token/device), or something you are (biometrics).
Explanation:
A secure password is long (at least 12 characters) and includes a mix of uppercase and lowercase letters, numbers, and special characters, making it difficult to guess or crack.
Explanation:
SQL injection is a code injection technique that exploits vulnerabilities in an application's database layer, allowing attackers to execute malicious SQL statements.
