Total Marks = 15% of total assessment for the unit. The purpose of this assignment is to report on important VPN security design characteristics and functions. The report must be specific to the given diagrams, use appropriate examples and detail VPN topologies and configurations. Submission guidelines: 1. You will prepare a formal report addressing all the questions with appropriate details. The word limit for the body of the assignment is 1500 words, Introduction-Conclusion 2. The assignment must be submitted using the online submission of the Moodle system and the assignment will be checked by Turnitin with any plagiarism reported to the MIT plagiarism board. Part I – Multiple Business Sites

Figure 1: Network Diagram of Site to Site VPN connection Using the given network diagram in Figure 1, justify each of these VPN implementation types (1 and 2).

1. GRE Tunnels (without IPsec protection) 2. GRE/IPsec using IPsec ESP in Tunnel Mode At minimum your report should address the following: • Explain in detail the description of each proposed VPN type, including

o Are all VPN attributes ready for implementation? Can you suggest any missing items? o What functionalities will VPN provide to the network in Figure 1?

o What are the security features it can provide to protect data? o What type of organization should use it?

• Is this particular implementation appropriate for the given network diagram? To address this make sure you address following points: o What are the advantages the proposed implementation brings to the given network? o What are the disadvantages the proposed implementation brings to the given network? o Is there a better solution available? Is it feasible to implement in the given network? Part II – Teleworker

Figure 2: Network Diagram of Remote VPN connection Using the given network diagram in Figure 2, justify the VPN implementation types suggested in Question 3 -4 and prepare a formal report.

3. Teleworker Connectivity (Assume Teleworker access without cryptographic technology such as IPSec) 4. Remote access VPN with SSL At minimum your report should address the following: • Explain in detail a description of the proposed VPN type, including

o Are all VPN attributes ready for implementation? Can you suggest any missing items? o What functionalities will it provide to the network in Figure 2 o What are the security features it can provide to protect data over internet?

o What type of organization should use it? • Is the particular implementation appropriate for the given network diagram? To address this make sure you address following points: o What are the advantages the proposed implementation brings to the given network? o What are the disadvantages the proposed implementation brings to the given network? o is there a better solution available? is it feasible to implement in the given network?

Marking criteria: Marks are allocated as indicated on each question, taking the following aspects into account:

Aspects Description Identification and Analysis and description Correctly identifying, appropriateness, discussion

Explanation/justification Description and justification Presentation and diagrams Structure, presentation, formatting, writing Reference style Proper referencing is required

Plagiarism Copy from another student, copy from internet source/textbook, copy from other sources without proper acknowledgement, etc

Extensions: Under normal circumstances extensions will not be granted. In case of extenuating circumstances—such as illness—a Special Consideration form, accompanied by supporting documentation, must be received before 3 working days from the due date. If granted, an extension will be only granted only by the time period stated on the consideration documentation; that is, if the illness medical certificate was for one day, an extension will be granted for one day only. Accordingly the student must submit within that time limit. Penalties will apply for late submission without an approved extension. Penalties: Academic misconduct such as cheating and plagiarism incur penalties ranging from a zero result to program exclusion. Marking Rubric for Assignment 1 Questions-Marks as shown Grade
