This typically involves providing something the user knows (e.g., a password), something the user has (e.g., a token or smart card), and/or something the user is (e.g., biometric data). By implementing MFA, organizations can strengthen their access control since attackers would need to compromise multiple factors to gain unauthorized access. MFA also helps in mitigating risks associated with compromised passwords, as gaining access requires more than just the password itself. Implementing MFA can significantly reduce the likelihood of unauthorized access, data breaches, and identity theft, while also helping organizations maintain regulatory compliance.
<b>Guide to Multifactor Authentication (MFA)</b>
What is Multifactor Authentication (MFA)? MFA is a method of confirming a user's claimed identity by utilizing more than one verification mechanism. It typically involves the knowledge, possession and inherence factors.
Why is MFA Important? Security breaches can be reduced by MFA because it requires the user to provide two or more verification factors to gain access. This can protect against hacking related identity thefts.
How does MFA work? MFA works by requiring any two or more of: something you know (password, PIN, pattern), something you have (smart card, hardware token), and something you are (biometrics, such as fingerprint or voice recognition).
Exam Tips: Answering Questions on Multifactor Authentication (MFA) 1. Understand the three types of authentication: what you know, what you have, and what you are. 2. Learn about the various forms of MFA such as two-step verification and 2-factor authentication. 3. Get familiar with examples of MFA scenarios. 4. Remember: The simultaneous occurrence of two or more factors (not the same type) constitutes MFA.
