Based on the mandatory access control model (DoD multi-level security model) we discussed in class. With the "no read up" and "no write down" rules in protecting data confidentiality, what access rights (read, write, both or none) a subject with a clearance (secret, { dog, cat, pig } ) have to the following documents with different security labels? a) Write to (secret; {dog}) b) Write to (top secret; {dog, cat, pig}) c) Read from (secret; {dog,cow}) d) Read from (confidential, { dog, pig, cat } ) e) Read from (confidential, {pig}) f) Write to (confidential, { dog, moose } )
