Network Segmentation Activity
Objective
This assignment requires the students to analyze the network diagram for PureLand Wastewater and make specific recommendations to improve network security per requirements below.
Instructions for assignment
1. Read your text: Establishing Secure enclaves
2. Refer to the document titled PureLand Network Diagram.pdf in the PureLand Case Study section of Blackboard. This is your starting point, and it has some deficiencies in its design that impact the cyber security for PureLand Wastewater. Your job is to use the concepts of establishing secure enclaves to improve the cyber security of PureLand’s network.
3. Define at least 3 enclaves within the PureLand network and fill in the following table defining these enclaves and how they will be monitored in the future state.
