Question 1

​Android devices automatically encrypt data stored on the device when a user activates the login password.

Accepted Answer

False

Question 2

​Which of the following is not an example of an authentication protocol?
A) ​password
B) ​PINs
C) ​fingerprint scanner
D) ​all of the above

Accepted Answer

All the options given (passwords, PINs, and fingerprint scanners) are examples of authentication protocols, therefore none of them should be excluded.

Question 3

​Which of the following terms would best match this definition: Transforms a message or data file in such a way that its contents are hidden from unauthorized readers.
A) ​authentication
B) ​encryption
C) ​ciphertext
D) ​decryption

Accepted Answer

Encryption is the process of converting a message or data file in such a way that its contents are hidden from unauthorized readers. It is a technique used to ensure confidentiality by making the information unintelligible to anyone who does not have the proper decryption key. Authentication involves verifying the identity of a user or system, ciphertext refers to the encrypted message, and decryption is the process of decoding an encrypted message with the proper key.

Question 4

​Password _________ is a measure in bits of a password's unpredictability.

Accepted Answer

The answer of ​Password _________ is a measure in bits...

Question 5

​It is not possible to encrypt a Windows hard drive volume.

Accepted Answer

It is possible to encrypt a Windows hard drive volume using built-in tools like BitLocker or third-party software.

Question 6

​There are various encryption methods, but __________ is the encryption standard currently used worldwide.
A) ​AES
B) ​DDoS
C) ​IMSI
D) ​TLS

Accepted Answer

AES (Advanced Encryption Standard) is currently the encryption standard used worldwide for securing sensitive information. It has replaced the outdated 3DES (Triple Data Encryption Standard) and offers a higher level of security with a 128-bit or 256-bit key size. DDoS (Distributed Denial of Service) and IMSI (International Mobile Subscriber Identity) are not encryption methods, and TLS (Transport Layer Security) is a protocol that provides secure communication over networks but is not an encryption method on its own.

Question 7

Brute force attacks methodically try every possible password until the correct one is found.​

Accepted Answer

Brute force attacks systematically try every possible combination of characters until the correct password is found, making it a time-consuming but potentially successful method of hacking into a system.

Question 8

​Which of the following is not a characteristic of a weak password?
A) ​Eight characters in length and include one or more uppercase letters, numbers, and symbols.
B) ​Uses default passwords such as password, admin, system, and guest.
C) ​Any sequence that includes a user name.
D) ​Use of words from a dictionary.

Accepted Answer

A password that is eight characters in length and includes one or more uppercase letters, numbers, and symbols is actually a strong password, not a weak one. The other options listed are characteristics of a weak password.

Question 9

​If you want to store passwords on your digital device, make sure to _________ the file in which they are stored.

Accepted Answer

The answer of ​If you want to store passwords on...

Question 10

​Passwords used as encryption ________ help to make hijacked data unusable.

Accepted Answer

The answer of ​Passwords used as encryption ________ help to...

Question 11

​Which of the following type of attack uses password-cracking software to generate every possible combination of letters, numerals, and symbols.
A) entropy​
B) ​massive
C) ​dictionary
D) ​brute force

Accepted Answer

Brute force attack is a type of attack that uses password-cracking software to generate every possible combination of letters, numerals, and symbols until the correct password is discovered. It is a slow process but can successfully crack any password if given enough time and resources.

Question 12

​A cryptographic __________ is a procedure for encryption or decryption.
A) ​firewall
B) ​ciphertext
C) ​key
D) ​algorithm

Accepted Answer

A cryptographic algorithm is a set of procedures used for encryption or decryption of data. They define the way in which encryption or decryption is carried out and ensure the confidentiality, integrity, and authenticity of the data being transmitted.

Question 13

​An original message or file that has not yet been encrypted is referred to as ciphertext.

Accepted Answer

The original message or file that has not yet been encrypted is referred to as plaintext. Ciphertext is the output of encryption, which is the scrambled version of plaintext that cannot be understood without the decryption key.

Question 14

​Conventional wisdom tells us that strong passwords are at least _____ characters in length and include one or more uppercase letters, numbers, and symbols.

Accepted Answer

The answer of ​Conventional wisdom tells us that strong passwords...

Question 15

​The single most effective security measure for digital devices is to password protect access to them.

Accepted Answer

Password protection is a basic and essential security measure for digital devices. It helps prevent unauthorized access and protects sensitive information. However, it is important to use strong and unique passwords, enable two-factor authentication, and keep passwords secure and updated to enhance their effectiveness.

Question 16

​OS X devices include a utility that automatically encrypts data stored locally.

Accepted Answer

The utility is called FileVault and it is included in all modern versions of OS X (now called macOS). It automatically encrypts data stored locally, providing enhanced security for users' files and personal information.

Question 17

A cryptographic ________ is a word, number, or phrase that must be known to encrypt or decrypt data.​

Accepted Answer

The answer of A cryptographic ________ is a word, number,...

Question 18

​A(n) _______ password is difficult to hack.

Accepted Answer

The answer of ​A(n) _______ password is difficult to hack....

Question 19

​Password entropy is a measure in _____ of a password's unpredictability.

Accepted Answer

The answer of ​Password entropy is a measure in _____...

Question 20

​If you feel more secure with a totally random and unique password for each of your logins, then a(n) _______________ is an excellent option.
A) ​keylogger
B) ​encryption key
C) ​password manager
D) ​personal firewall

Accepted Answer

A password manager generates and stores a unique password for each of your logins, allowing you to have a strong and secure password without having to remember multiple different passwords.
