I think you are right, though the level of abstraction providedd by the
network elements may be quite low if you want network-wide rather than box
by box management. For example, ACLs can provide network-wide perimeter
defense, with appropriate clauses embedded in the edge routers. It's all
there in the routers, but it is not expressed directly as a network-wide
constraint (which might help manage ACLs).
