Situational Questions

  • 11. If you received a report of a potential data breach, what steps would you take to investigate and respond?
    -I would immediately escalate the issue to my supervisor and gather all necessary information such as the affected systems and potential sources of the breach.

  • 12. How would you handle a situation where an employee violated company security policies?
    -I would first assess the severity of the violation and document all relevant information. I would then follow the company's disciplinary procedures and educate the employee on the importance of adhering to security policies and the potential consequences of non-compliance.

    -I would present a thorough report and explain the potential risks and impact of the weakness, along with a proposed solution and estimated cost. I would also provide examples of similar incidents in other organizations to highlight the importance of addressing the weakness.
  • 14. How would you handle a situation where a user has fallen victim to a phishing attack?
    -I would immediately disconnect the affected system from the network to prevent further damage.

I would then educate the user on how to recognize and avoid similar attacks in the future.
  • 15. If a company's network has been compromised by advanced persistent threats, how would you approach the incident response and recovery process?

I would also work closely with law enforcement if necessary and communicate clearly with stakeholders throughout the process.

Technical Questions

  • 19. Can you explain the concept of multi-factor authentication?
    -Multi-factor authentication is a security mechanism that requires users to provide multiple forms of identification, such as a password and a unique code sent to their phone, in order to access a system or account.
  • 20. How do you conduct a vulnerability assessment on a network?
    -First, I would gather information about the network and its assets. Then, I would scan the network for known vulnerabilities and analyze the results to identify any potential weaknesses.
