1. An apparatus comprising: a memory that stores a plurality of tokens indicating that a user is attempting to access a resource; and a processor that: determines a related resource that shares a relationship with the resource, wherein: the resource is a composite resource; the related resource is a sub-resource of the composite resource; and the related resource is accessed in conjunction with accessing the resource; receives a risk token computed based at least in part upon the resource and the related resource; determines a numeric authorization level for the user based at least in part upon the plurality of tokens and the risk token, the numeric authorization level indicating whether the user is authorized to access the resource, wherein the composite resource comprises at least one sub-resource that the user is not authorized to access based on the numeric authorization level and at least one sub-resource that the user is authorized to access based on the numeric authorization level; compares the numeric authorization level to a numeric threshold; determines, based at least in part on the comparison between the numeric authorization level and the numeric threshold, that the user is authorized to access the related resource; communicates a decision token indicating that the user is authorized to access the resource and the related resource; receives a recomputed risk token computed based at least in part upon: a form of authentication performed by the user; and the presence of network jitter; re-determines determine the numeric authorization level based at least in part upon the recomputed risk token; determines, based at least in part upon the recomputed risk token, that the user is authorized to access the at least one sub-resource; and communicates a second decision token indicating that the user is authorized to access the resource, the related resource, and the at least one sub-resource.
