Abstract: A technique to implement access control from within an application begins by dynamically-generating a “management scope” for a transaction associated with a set of managed resources. The management scope is a collection of permissions defined by at least one of: a set of roles, and a set of resource administration rights, that are assigned to a first operator that issues the transaction. As the transaction executes, a request to alter the transaction is then received from a second operator. According to the technique, the management scope for the transaction and associated with the first operator is then evaluated against a management scope associated with the second operator. Upon determining the management scope associated with the first operator has a given relationship to the management scope for the second operator, the transaction is permitted to be altered in response to the request. The given relationship is scoped by one or more rules.
