Question 1

The correct answer is: c: Encryption

Encryption is the use of complex algorithms to scramble sent information into random characters and symbols so that it cannot be read by any unauthorised users if intercepted.

Question 2

The correct answer is: a: To prove the identity of a website and start an encrypted session.

Options B, C, and D are incorrect as SSL certificates only mean the website uses an encrypted session to secure data and do not guarantee that a website uses two-factor authentication, is legitimate, or does not sell data.

Options A, C, and D are all true statements about spyware.

Question 3

The correct answer is: d: J4@v£h7m%

Since this password includes the most numbers, complex symbols, and letters, it is the strongest password.

Question 4

The correct answer is: b: CAPTCHA

A CAPTCHA is a security feature designed to prevent spam or abuse from automated bots by requiring that users take a simple test to verify that they are a human. It is most commonly used in web forms and contains tests that are impossible for most automated programs to recognise.

Question 5

The correct answer is: a: Using strong and complex passwords and using a password manager to remember them.

Question 6

The correct answer is: c: Because the latest versions of antiviruses contain the latest files that are required for detecting the newest viruses.

Antiviruses have to be regularly updated and maintained to ensure that the latest virus definitions are available and without updating, the antivirus would not be able to identify and block the latest threats.

Options A and B are incorrect as an antivirus offers no such guarantees.

Option D is incorrect as it is unlikely that an antivirus will stop working just because it isn't updated to the latest version. Users just won't be protected against the latest threats.

Question 7

The correct answer is: a: True

Because SSL and TLS are so closely related, it is common to refer to TLS as SSL/TLS.

Question 8

The correct answer is: d: It is a compulsory security feature on nearly all websites.

Two-factor authentication is usually an optional feature that you can enable if you want to add an extra layer of security to your account. However, some online services, particularly banking sites and online shopping sites, may require you to enable two-factor authentication to your account without giving you an option to disable it for your security.

Options A, B, and C are all true statements about two-factor authentication.

Question 9

The correct answer is: b: When encrypting stored data, like documents

Symmetric encryption is when a single key is used to encrypt and decrypt a message and all parties use the same key. Stored data, especially confidential documents, sometimes needs to be encrypted to prevent unauthorised access as if they gained access to a computer system, they would not be able to read any contents of the file. Stored data is usually encrypted using symmetric encryption.

Options A, C, and D are incorrect as they are most likely to use asymmetric encryption.

Question 10

The correct answer is: a: Attackers have been focusing on discovering TLS exploits that can be used to compromise data security and integrity.

Question 11

The correct answer is: d: All of the above

Options A, B, and C are all examples of ways to prevent online fraud.

Question 12

The correct answer is: b: When the recipient receives it.

For example, HTTPS, the secure version of the Hypertext Transfer Protocol used for communicating over the World Wide Web uses SSL/TLS to encrypt data, convert plaintext to ciphertext, and then decrypts the message when the recipient receives it.

Question 13

The correct answer is: a: 1

It is definitely possible to have more than one antivirus program installed. However, it is not recommended. Having more than one active antivirus program can result in conflicts between the two programs and additional use of resources, such as CPU and memory, causing a computer to become much slower. Installing more than one antivirus program will not provide any extra security for a computer. In fact, it might cause a computer to become unprotected due to the two conflicts between programs.
