The passage around this formula

Represent a deployed system j as Aj=(Mj,Cj,Tj,Pj,Ej,Sj,Oj)\mathcal A_j=(M_j,C_j,T_j,P_j,E_j,S_j,O_j). where M is model policy, C context and state, T tools and extensibility, P permissions, E execution isolation, S surfaces and handoff, and O organizational controls. Comparing only M discards most of what users buy and most of what defenders must secure.
