Identified at least three network hardening strategies for each given network layout.

Use the following questions to start the discussion:

*Are they any Network Security Defense Tools that we can add to these topologies?

*Where will you place them physically and in what Layer of the OSI Model?

• Layer 7 - Application
• Layer 6 - Presentation
• Layer 5 - Session
• Layer 4 - Transport
• Layer 3 - Network
• Layer 2 - Data link
• Layer 1 - Physical
