Patent attributes
A computing resource service provider grants a first set of security permissions to a principal (e.g., a user) which may be used to access a plurality of computing resources. The permissions may be associated with a first security token. The principal may access resources using the first set of security permissions, and a system (e.g., a service provider) may identify a subset of security permissions that are sufficient to provide access to the computing resources accessed by the principal using the first set of permissions. The subset may be associated with the principal. In some cases, the principal operating under the subset of permissions may be denied access to a computing resource and may be granted access to the computing resource by operating under the first set of permissions.
