1. A method for enforcing policies in an enterprise, the method comprising: receiving, by a computer system, a reference to a first service policy; receiving, by the computer system, a first policy attachment scope, the first policy attachment scope identifying a type of resource in the enterprise; generating, by the computer system, a first global policy attachment metadata using the first service policy and the first policy attachment scope, the first global policy attachment metadata defining an attachment of the first service policy to the type of resource identified in the first policy attachment scope; receiving, by the computer system, a request to access a resource, wherein the resource is the type of resource identified in the first policy attachment scope; determining, by the computer system, an effective set of policies for the resource using the first global policy attachment metadata based at least in part on determining that the first service policy is in the effective set of policies for the resource; controlling, by the computer system, access to the resource responsive to the request using the determined effective set of policies at least in part by granting, by the computer system, the request to access the resource based upon the effective set of policies, wherein the type of resource identified by the first policy attachment scope corresponds to a first level in an enterprise containment hierarchy, the levels are ordered by breadth from a broad level to a narrow level, a first type of resource associated with a broader level contains one or more types of resources associated with a narrower level, wherein the first policy attachment scope contains additional types of resources if the type of resource identified by the first policy attachment scope corresponds to a level that is broader than the level that corresponds with the additional types of resources, and wherein the requested resource corresponds to a level that is narrower than the level corresponding to the first policy attachment scope.
