When answering this question, emphasize your knowledge of network security principles and best practices. Discuss specific strategies and technologies you use to ensure network security, such as firewalls, intrusion detection/prevention systems, encryption, and secure access controls. Provide examples from your past experience where you successfully implemented these measures. For instance, you might say:
"In my previous role, I ensured network security by implementing a multi-layered security approach. This included deploying firewalls to monitor and control incoming and outgoing network traffic, using intrusion detection systems to identify potential threats, and encrypting sensitive data to protect it from unauthorized access. Additionally, I established strict access controls to ensure that only authorized personnel could access critical network resources. By regularly updating and patching systems, I was able to mitigate vulnerabilities and maintain a secure network environment."
