Question

Architects designing a multilevel public-safety records system must choose a classic model based on protection goals. When the dominant requirement is stopping unauthorized disclosure across clearance levels, which selection is most appropriate?

Accepted Answer

Select a confidentiality-oriented model such as Bell-LaPadula when preventing read-up disclosure is the primary goal — Pick the model the way gear gets picked for a mission: secrecy problem? Use a confidentiality model. Integrity problem? Use an integrity model. Do not grab Biba just because the word model sounds fancy.

Answer

Select Biba because integrity models automatically satisfy confidentiality

Answer

Select Clark-Wilson solely because public safety involves commercial invoices

Answer

Ignore models and rely on a single shared password for every clearance band
