When answering this question, it's important to demonstrate a comprehensive understanding of network security principles and best practices. Start by outlining a structured approach to securing a network, such as conducting a risk assessment, implementing security policies, and deploying technical controls. Mention specific technologies and practices, such as firewalls, intrusion detection systems, encryption, and regular security audits. Provide examples from your past experience where you successfully secured a network or mitigated a security threat. This will show that you not only understand the theory but also have practical experience in applying these measures. For example:
"To secure a company's network, I would start with a thorough risk assessment to identify potential vulnerabilities. Based on the findings, I would develop and implement comprehensive security policies. I would deploy technical controls such as firewalls, intrusion detection systems, and encryption to protect data in transit and at rest. Regular security audits and continuous monitoring would be essential to ensure the network remains secure. In my previous role, I successfully implemented these measures, which resulted in a significant reduction in security incidents."
