Three Discussion Questions about Network Security

Which is more difficult to secure: wireless or wired networks? Why?

Explain the differences between Wide Area Networks (WAN), Metropolitan Area Networks (MAN), and Campus Area Networks (CAN).

Which type of network is more likely to be directly attacked by nation-state sponsored attackers? Why?

Which is more difficult to secure: wireless or wired networks? Why?
In the past the wired networks were considered more secure than wireless networks. Nowadays both types of networks are considered secure with the condition to apply the proper setup for wireless networks. In the context of the class this matter can be regarded with respect to applying the most appropriate cryptographic protocols for protecting the exchanged traffic. More than this, currently it is very unlikely to find pure wired/wireless networks. In most of the situations the networking environment had become heterogeneous (different types of interconnected network segments and distinct operating systems across the network)....
