Divisions and classes:
The TCSEC defines four divisions: D,C,B and A
where division A has the highest security. Each division represents a
significant difference in the trust an individual or organization can place on
the evaluated system. Additionally divisions C, B and A are broken into a series
of hierarchical subdivisions called classes: C1, C2, B1,B2, B3 and A1.
