1. An apparatus for abstraction in a token-based environment, comprising:

  • a memory operable to store a plurality of tokens associated with a session, wherein;

    the session facilitates access to a resource by a user and the session is identified by a session token; and

    the plurality of tokens comprises a resource token indicating a form of authentication provided by the resource, a virtual machine token corresponding to a virtual machine provisioned to the user, and a compliance token indicating that a device of the user comprises sufficient hardware and firmware to access the resource; and

    a processor operable to;

    determine a second plurality of tokens required to facilitate determination of a risk token, wherein;

    the risk token is used to facilitate determination of an access decision to the resource; and

    the second plurality of tokens is determined based on a token-based rule that indicates that a dataset token representing the plurality of tokens can be generated if the plurality of tokens comprises the second plurality of tokens;

    determine that the plurality of tokens comprises the second plurality of tokens;

    generate the dataset token representing the plurality of tokens in response to the determination that the plurality of tokens comprises the second plurality of tokens;

    communicate the dataset token to facilitate generation of the risk token;

    receive the risk token, wherein the risk token is based at least in part on the dataset token; and

    correlate the risk token with the session token to facilitate determination of the access decision to the resource, wherein the risk token impacts a trust level indicating the security provided by the form of authentication provided by the resource.
