I am taking networking class right now. The teacher wants us to write a report on any topic related to network. I choose network security. The teacher said network security is too broad and that I need to narrow it down. He said he wants me to focus more on network part than the application. What does he mean by that and what kind of topics are there for networking part in network security?

You can write about the increasing use of wireless networks and the related security issues with those
im not sure what your lecturer is asking, but it could be either a general paper or more about protocols etc.

network layer is level 3 of the osi so you should probly research what this layer is made up of and how it works in regards to the network

It sounds like he is wanting you to focus on one particular topic. If you are wanting to write about network security in the network layer I would use stateful and stateless firewalls. This is one of the biggest areas of security in the network layer. It also concerns itself more with hardware than software and has no ties to the application layer.

i think what he means by aspect of security is something like:
- wifi security (wep/wpa/... encryption...)
- firewalling (different brands/types)
- VPN (also different ways to connect, protocols)
- IDS (snort) / network anti-virus
- Proxy server
- or you can go more organisational and take something like security policy's
