   	&lt;Abstract>Aeolus is a programming platform that supports the development of secure applications that preserve the confidentiality of information entrusted to them. An important part of the Aeolus platform is an auditing subsystem that maintains a log in which it stores information about every security related event that occurs while applications run. The log allows later analysis to determine whether the security policies of the application have been followed. For an Aeolus user, analyzing an Aeolus event log can prove to be a daunting task, especially when this log grows to include millions of records. Similarly, storing such an event log can be very costly.
