The network coordinative forensics technology base on data provenance

摘要

At present there is no good security tool that can directly associate analysis to the multi-step attack on network, and reconstruct invading process to obtain the criminal evidence. So a new approach of network coordinative forensics based on data provenance was presented: Set up a log server with SYSLOG mechanism, obtain logs provenance databases with Perm rewrite technology, position multi-step attacker with where provenance, and reconfiguration attack process with why provenance. Data provenance theory and experiment results proved that the new approach is feasible and effective.
