Recent work has shown that conventional operating system audit trails are insufficient to detect low-level network attacks. Because audit trails are typically based upon system calls or application sources, operations in the network protocol stack go unaudited. Earlier work has determined the audit data needed to detect low-level network attacks. We describe an implementation of an audit system which collects this data and analyze the issues that guided the implementation. Finally, we report the performance impact on the system and the rate of audit data accumulation in a test network.
