Hi.
I’m working on DARPA 1998 intrusion detection dataset.
When I run snort on this dataset (outside.tcpdump file), snort don’t generate complete list of alerts. It means snort start from last few hours of tcpdump file and generate alerts about this section of file and all of packets in first hours are ignored. Another problem in generatin alert is in time stamp of generated alerts. This means when I run snort on a specific day of dataset, snort insert incorrect time stamp for that alert.
The configuration and command line statement and other information about my research are:
Snort version: 2.8.6
Operating system: windows XP
Rule version: snortrules-snapshot-2860_s.tar.gz
