1. Explain in detail with examples each of the following fundamental security design principles: economy of mechanism, fail-safe default, complete mediation, open design, separation of privilege, least privilege, least common mechanism, psychological acceptability, isolation, encapsulation, modularity, layering, and least astonishment.

Security in general means the protection of an asset. In the context of computer and network security, explore and explain what assets must be protected within an online university. What the threats are to the security of these assets, and what countermeasures are available to mitigate and protect the organization from such threats. For each of the assets you identify, assign an impact level (low, moderate, or high) for the loss of confidentiality, availability, and integrity. Justify your answers.
