Bella

Bell-LaPadula

The following reference(s) were/was used to create this question:

Separation of duty is necessarily determined by conditions external to
the computer system. 

The Clark-Wilson scheme is includes the requirement that the system
maintain the separation of duty requirement expressed in the access
control triples. 

Enforecement is on a per-user basis, using the user ID from the access
control triple.
