Engineering

1.Assume a system enforces both the BLP and Biba properties. For BLP thatmeans read down/write up only and for Biba it means read up/write down only. Assumealso that two models use identical levels for both security and integritySL = security clearance for level L = integrity clearance for level LSC = security category set for cat. C = integrity category set for cat CProve that in this system a subject can only read and write at his own level
2.a.In Lipner's model consider moving a program from development into production. What are the starting and ending security and integrity levels of this object
2b. Who in Lipner's model can make this change?
2c. Explain the reads and writes necessary to make this change and justify the read and write using Lipner's matrix
