How would you make sure a computer network is secure?

This question is designed to assess your technical knowledge and problem-solving skills related to network security. Interviewers seek to understand your approach to identifying potential vulnerabilities, implementing security measures, and staying current with best practices in cybersecurity. They are also looking for insight into your critical thinking and analytical abilities when facing security challenges.

Start by detailing a strategy that includes assessing potential vulnerabilities and risks, using firewalls, encryption, and regular updates as part of your security protocols. For example, you could say, 'To ensure a computer network is secure, I would conduct regular vulnerability assessments and implement firewalls alongside intrusion detection systems. Additionally, I would ensure that all software and systems are regularly updated to protect against the latest threats.' Emphasize the importance of ongoing training and awareness for all users to recognize potential security threats.
