Question Details

 the primary reason for storing a hash of the password





1. An information system that processes sensitive information is configured
to require a valid userid and strong password from any user. This process
of accepting and validating this information is known as:
a. Authentication
b. Strong authentication
c. Two-factor authentication
d. Single sign-on


2. The reason that two-factor authentication is preferable over ordinary
authentication is:
a. Two-factor authentication is more difficult to crack
b. It relies upon something the user knows
c. It relies upon something that the user has
d. Two-factor authentication uses stronger encryption algorithms


3. When an information system authenticates a user based on “what the user
is,” this refers to the use of:
a. Authorization based upon the user- job title
b. Role-based authentication
c. Two-factor authentication
d. Biometric authentication


4. In an information system that authenticates users based on userid and
password, the primary reason for storing a hash of the password instead of
storing the encrypted password is:
a. No one, even system administrators, can derive the password
b. Hashing algorithms are less CPU-intensive than encryption algorithms
c. Hashed passwords require less storage space than encrypted passwords
d. Support personnel can more easily reset a user- password when it is
hashed


5. The primary reason why users are told to use strong passwords is NOT:
a. It is more difficult to “shoulder surf” a strong password because of
the additional keystrokes
b. Strong passwords are more difficult for others to guess
c. Weak passwords are susceptible to dictionary attacks
d. Passwords based on easily-discovered facts such as birthdays, spouse
and pet names are easily guessed
