What interview questions can come from network security?

Network security focuses on protecting systems and traffic from unauthorised access and attacks. Students should understand concepts such as authentication, firewalls, secure protocols and threat awareness. This makes network security more valuable when it is supported by hands-on practice and a clear explanation of what you built. This point is specifically relevant to the network security aspect of MCA study. For this specific question about network security, the practical takeaway is to relate the concept to your own MCA learning goal.
