2. Generate a BLP lattice structured system where the objects and subjects are appropriately levelled to give access consistent with the access control matrix below. You need to describe the process by which you obtain your lattice. R and W correspond, respectively, to read and append. You are to use only the mandatory BLP rules, and a default allow in place of the discretionary rule. Be sure to add a level as necssary to ensure this is a lattice. 0₁ S₁ R S2 R S3 R RW RW S₁ R S5 R S6 R 02 03 04 05 06 R R RRRW R R W W W W W W R R
