Method and apparatus for token-based reassignment of privileges

A method for privilege-based access control in a token-based environment, comprising:

• monitoring a session, wherein the session facilitates a user's access to a resource, the user granted a privilege associated with accessing the resource based at least in part upon a first risk token;
• detecting a change in at least one token of a plurality of tokens during the session, the change associated with the privilege granted to the user;
• communicating the first risk token and a token associated with the change;
• receiving a second risk token associated with the first risk token the token, wherein the second risk token indicates an increased risk associated with the change;
• determining, by a hardware processor, to revoke the privilege based on the second risk token;
• generating, by the processor, a second token associated with the determination to revoke the privilege based at least in part upon the second risk token;
• and
• communicating the second token to facilitate the revoking of the privilege;
• determining, by the processor, based on a token-based rule, to grant a new privilege based on the second risk token, wherein the second token is further associated with the determination to grant the new privilege, and wherein communicating the second token facilitates the granting of the new privilege;
• determining, by the processor, that a form of authentication associated with the session has been performed;
• determining, by the processor, based at least in part upon the determination that the form of authentication has been performed, that the revoked privilege should be granted;
• generating a third token associated with the determination to grant the revoked privileged;
• and
• communicating the third token to facilitate the granting of the revoked privilege.

One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

• monitor a session, wherein the session facilitates a user's access to a resource, the user granted a privilege associated with accessing the resource based at least in part upon a first risk token;
• detect a change in at least one token of a plurality of tokens during the session, the change associated with the privilege granted to the user;
• communicate the first risk token and a token associated with the change;
• receive a second risk token associated with the first risk token and the token, wherein the second risk token indicates an increased risk associated with the change;
• determine to revoke the privilege based on the second risk token;
• generate a second token associated with the determination to revoke the privilege based at least in part upon the second risk token;
• and
• communicate the second token to facilitate the revoking of the privilege;
• determine, based on a token-based rule, to grant a new privilege based on the second risk token, wherein the second token is further associated with the determination to grant the new privilege, and wherein communicating the second token facilitates the granting of the new privilege;
• determine that a form of authentication associated with the session has been performed;
• determine, based at least in part upon the determination that the form of authentication has been performed, that the revoked privilege should be granted;
• generate a third token associated with the determination to grant the revoked privileged;
• and
• communicate the third token to facilitate the granting of the revoked privilege.
