Consider the following system enforcing Biba's strict integrity policy for a software vendor.

The defined integrity levels for an access class are released (rel) > beta > demonstration (demo). The defined set of integrity categories are {internal, partner, customer} or {in, pa, cu}.

Consider a subject with an access class of (beta, {in, pa} ).

a)Can this subject read an object with an access class of (beta, {pa, cu} )?

b)Can this subject read an object with an access class of (rel, {pa, cu} )?

c)Can this subject read an object with an access class of (demo, {pa} )?

d)Can this subject write an object with an access class of (beta, {pa, cu} )?

e)Can this subject write an object with an access class of (rel, {cu} )?

f)Can this subject write to an object with an access class of (beta, {in,cu})

g)Can this subject invoke a subject with an access class of (beta, {in,pa} )?

h)Can this subject invoke a subject with an access class of (rel, {in, pa} )?

i)Can this subject invoke a subject with an access class of (demo, {in, pa, cu})?

j)Can this subject write an object with an access class of (demo, {in, pa, cu})?
