Secure customer use of an e-commerce application can BEST be accomplished through:
A.
data encryption.
B.
digital signatures.
C.
strong passwords.
D.
two-factor authentication.
Explanation:
Encryption would be the preferred method of ensuring confidentiality in customer communications
with an e-commerce application. Strong passwords, by themselves, would not be sufficient since
the data could still be intercepted, while two-factor authentication would be impractical. Digital
signatures would not provide a secure means of communication. In most business-to-customer (Bto-C) web applications, a digital signature is also not a practical solution.
