Abstract
Methods and apparatus are described for processing transactions from untrusted sources which reduce the risk of a maliciously instructed transaction being processed at a target environment and thus preventing undesirable behaviour resulting from processing the transaction occurring at the target environment. An execution manager is provided to process transactions/portions of transactions in an emulated environment and monitor the resultant effects. Following execution of the transaction at the emulated environment, it is determined whether undesirable behaviour occurred at the emulated environment and whether the transaction may be executed in the target environment. The method enables transactions from untrusted sources to be processed with minimal risks of malicious consequences occurring at the target environment.
