Network Management and Administration Tool: Using OPNET IT Guru Academic -Edition Objective: The objective of this lab is to study the role of firewalls and Virtual Private Networks (VPNs) in providing security to shared public networks such as the Internet. -In this project you will do the following tasks: 1- set up a network where servers are accessed over the Internet by customers who have different privileges. 2- You will study how firewalls and VPNs can provide security to the information in the servers while maintaining access for customers with the appropriate privilege. -Questions 1) From the obtained graphs, explain the effect of the firewall, as well as the configured VPN, on the database traffic requested by Sales A and Sales B. 2) Compare the graphs that show the received HTTP traffic with those that show the received database traffic. 3) Generate and analyze the graph(s) that show the effect of the firewall, as well as the configured VPN, on the response time (delay) of the HTTP pages and database queries. 4) In the Firewall_VPN scenario we configured the VPN node so that no traffic from Sales A is blocked by the firewall. Create a duplicate of the Firewall_VPN scenario and name the new scenario Q4_DB_Web. In the Q4_DB_Web scenario we want to configure the network so that: a. The databases in the server can be accessed only by the people in the Sales A site. b. The web sites in the server can be accessed only by the people in the Sales B site. Include in your report the diagram of the new network configuration including any changes you made to the attributes of the existing or added nodes. Generate the required graphs to show that the new network meets the above requirements. -Lab Report Prepare a report that follows the guidelines explained in Lab 0. The report should include the answers to the above questions as well as the graphs you generated from the simulation scenarios. Discuss the results you obtained and compare these results with your expectations. Mention any anomalies or unexplained behaviors.
