How to answer: Define 2FA as a security process requiring users to provide two different authentication factors, typically something they know (password) and something they have (token or mobile device).

Example Answer: "Two-Factor Authentication adds an extra layer of security by requiring users to provide two different types of identification before accessing an account. This commonly involves a combination of a password and a temporary code sent to a mobile device or generated by an authentication app."

10. What is the role of encryption in data security?

The interviewer is interested in your understanding of encryption as a fundamental data protection measure.

How to answer: Explain that encryption transforms data into a coded format, making it unreadable without the appropriate decryption key. Emphasize its role in protecting sensitive information from unauthorized access.

Example Answer: "Encryption is crucial for data security as it transforms information into a secure format that can only be deciphered with the correct decryption key. This ensures that even if unauthorized parties gain access to the data, they cannot interpret or use it without the proper credentials."

11. What is a Security Information and Event Management (SIEM) system?

The interviewer is evaluating your familiarity with tools used in security monitoring and incident response.

How to answer: Describe SIEM as a comprehensive solution that aggregates and analyzes security data from various sources to detect and respond to security incidents.

12. How do you assess the security posture of an organization?
