A Log Correlation Model to Support the Evidence Search Process in a Forensic Investigation
Jorge Herrerías, Roberto Gómez · 2007
Computer forensics searches for evidence to reassemble the actions that led the system from a secure state to the moment an intrusion was detected. The main source of data for a forensic investigation is the information provided by log files. Log files are generated by applications to keep a register of the actions occurred on the system. However, the massive amount of recorded events complicates the forensic investigation. A model composed by a set of agents in order to collect, filter, normalize, and to correlate events coming from diverse log files is proposed in this paper. The purpose of the model is to assist the analyst in the evidence search process of a forensic investigation
