The two-factor authentication (2FA) is a security measure that requires users to provide two different types of authentication credentials before they are granted access to a resource. In this case, the security engineer has enabled 2FA on all workstations. Let's analyze each option to determine which are the most secure approaches.
A. Password and security question: This approach uses something the user knows (password) and something the user has to recall (security question). However, security questions are not always effective, as attackers can often find the answers to common security questions through social engineering or online research. Therefore, this option is not the most secure.
B. Password and CAPTCHA: CAPTCHA is a test designed to be easily solved by humans but difficult for machines. Although CAPTCHA can prevent automated attacks, it does not provide any additional security to prevent human-based attacks. Therefore, this option is not the most secure.
C. Password and smart card: This approach uses something the user knows (password) and something the user has (smart card). Smart cards can store sensitive information and can be difficult to duplicate or steal. Therefore, this option is one of the most secure.
D. Password and fingerprint: This approach uses something the user knows (password) and something the user is (fingerprint). Biometric authentication, such as fingerprints, can be difficult to replicate, making it one of the most secure approaches.
E. Password and one-time token: This approach uses something the user knows (password) and something the user has (one-time token). One-time tokens are generated for a single use and can be difficult to intercept or duplicate. Therefore, this option is one of the most secure.
F. Password and voice: This approach uses something the user knows (password) and something the user is (voice). Biometric authentication, such as voice recognition, can be difficult to replicate, making it one of the most secure approaches.
Therefore, the two most secure approaches are C (password and smart card) and either D (password and fingerprint), E (password and one-time token), or F (password and voice). These options provide a strong defense against various attack vectors and reduce the likelihood of unauthorized access.
