Your design proposal will be focused on how your design will ensure that the secured network can fully support the following three aspects:

• Confidentiality: The classified data sent by the sender must be comprehensible only to the intended receiver.
• Integrity: The classified data sent by the source node should reach the destination node unaltered. It should be impossible for any malicious node in the network to tamper with the data during transmission.
• Availability: The network of the data classification system should remain operational all the time.

Now, your design tasks are to identify at least 3 technical solutions for each of the 3 aspects. You will need to specify each technical solution first, and then make the comparison for all of the technical solutions chosen for 1 specific aspect. All of these content will become the main part of your design proposal document. Additionally, you will need a short Introduction section, which briefly presents the reason for creating this design proposal, and a short Conclusion section, which will briefly summarize the main takeaways of this design proposal.
