US Patent 10346626 Versioned access controls

Methods and systems for implementing versioned access controls are disclosed. A first task is added to a first workflow with a first version of a default role. A second version of the default role is generated after the first task is added. A second task is added to a second workflow with the second version of the default role. The first version and the second version each comprise one or more permissions for using one or more computing resources. The first task is performed using the permissions in the first version of the default role. The second task is performed using the permissions in the second version of the default role.
