An information flow control system regulates all activities that concern information security. By recording all the operations monitored by Aeolus, our audit trails capture all actions that can affect system security. In our system, event records are collected on each system node and shipped to a centralized location, where they are stored and processed. To correlate audit trail events of different system nodes we store event dependencies directly in the event records. Each audit trail record keeps links to its immediate predecessors. Therefore, our audit trails form dependency graphs that capture the causal relationship among system events. These graphs can be used to reconstruct the chains of events leading to a given system state. Our results show that audit trail collection imposes a small overhead on system performance. 2010-09-29T21:00:22Z 2010-09-29T21:00:22Z 2010-09-29 http://hdl.handle.net/1721.1/58772 MIT-CSAIL-TR-2010-048 86 p. application/pdf |
