J308 Module 7 Q&A
Why are passcodes more secure than PINs?
a. passcodes are longer
b. passcodes are more difficult for hackers to guess
c. passcodes contain letters as well as numbers
d. all - (correct answer)all
What is the advantage of having one setting to activate a password and another setting
to activate encryption?
a. there can be separate passwords for login and encryption so that a hacker who
discovers a login password can't access unencrypted data
b. passwords are shorter than encryption strings, so they are easier to remember
c. there is no advantage to having separate settings, and because of this iOS handles
security better than Android OS - (correct answer)there can be separate passwords for
login and encryption so that a hacker who discovers a login password can't access
encrypted data
T/F: A Windows laptop computer is usually configured so that the PIN is also a key used
to encrypt and decrypt the storage volume - (correct answer)False

Will the hacker who found your device crack the password more quickly with a brute
force attack or a dictionary attack?
a. a brute force attack

A ___ attack usually cracks passwords in less time than a brute force attack - (correct
answer)dictionary

answer)entropy

software
What is the purpose of heuristic analysis?
a. to analyze virus signatures
b. to add virus signatures to the virus database
c. to detect virus-like commands or behaviors
d. to discover the time when malware might deliver its payload - (correct answer)to
detect virus-like commands or behaviors
What is the purpose of putting malware into quarantine?
a. it prevents users from inadvertently running the malware
