Ethical Hacking Essentials Practice Test

Which of the following countermeasures can assist users in reducing the chances of identity theft?

1. Enable two-factor authentication on all online accounts

2. Making passwords publicly known

3. Using the same password across multiple sites

4. Storing passwords in plain text files

The correct answer is: Enable two-factor authentication on all online accounts

Enabling two-factor authentication on all online accounts is an effective countermeasure for reducing the chances of identity theft. This security process requires users to provide two different types of information to verify their identity. Typically, the first factor is something the user knows, like a password, while the second factor is something the user possesses, such as a mobile device that receives a one-time code. This additional layer of security significantly enhances the protection of online accounts, making it more difficult for unauthorized individuals to gain access, even if they have obtained the user’s password. In contrast, making passwords publicly known, using the same password across multiple sites, and storing passwords in plain text files all pose serious security risks. Publicly sharing passwords opens accounts to anyone who sees them. Using the same password across different accounts increases vulnerability; if one account is compromised, all accounts using that same password are at risk. Similarly, storing passwords in plain text files makes them easily accessible to anyone who gains access to the computer or storage device.
