Question

what is the significance of using a yubikey in cybersecurity? it can be easily hacked it provides a physical form of two - factor authentication it is a type of password manager it is a form of biometric security why is it important to understand ones threat model in cybersecurity? 1 poin to determine the level of security needed to avoid using any security measures to ensure all passwords are the same to eliminate the need for multi - factor authentication what is a common misconception about hackers according to rachel tobac? 1 point all hackers are criminals hackers are always ethical hackers only work for companies hackers do not use technology

Explanation:

• First Question: YubiKey is a hardware device. Two - factor authentication (2FA) adds an extra layer of security. A physical form of 2FA (something you have) along with something you know (password) is more secure. YubiKey is not easily hacked, it's not a password manager (which stores passwords), and it's not biometric (which uses physical traits like fingerprints).
• Second Question: A threat model helps in assessing risks. Based on the identified threats (e.g., level of sophistication of attackers, types of data at risk), the appropriate level of security (e.g., encryption strength, access controls) can be determined. Avoiding security measures, having same passwords, or eliminating multi - factor authentication are all bad security practices.
• Third Question: In reality, there are ethical hackers (white - hat hackers) who test systems for security vulnerabilities. So, the misconception is that all hackers are criminals. Hackers are not always ethical (there are black - hat hackers), they don't only work for companies (some are independent attackers or in cyber - crime groups), and they definitely use technology.

Answer:

1. It provides a physical form of two - factor authentication
2. To determine the level of security needed
3. All hackers are criminals
