Re: Snort against DARPA 1999 Dataset

How do you know they are false positives?  Because the names aren't the same?

Where is the link to said dataset?

I've used of DARPA data set because of two reasons:

1. Because of its good documentation about attacks. I couldn't find any data set that has documents same as DARPA 
data set. Its documentation helps me to calculate false positives and detection rate.

2. Because of its popularity. It is used by many papers and it helps me to compare my method with other methods. 

Do you know any newer dataset that can help me in this case?

Yes, it generated 17000 alerts but when I compared these alerts with DARPA dataset master identification file, I 
found that any of them is true positive alert.
 
Link to DARPA dataset truth file: http://www.ll.mit.edu/mission/communications/ist/files/master_identifications.list

Thanks & Regards,

You said it generated 17,000 alerts, but then you say it didn't generate any alerts.  Which one is it?

Hello,

I'm working on running snort with DARPA dataset for 4 weeks but I gain any success to detection its attacks by 
snort.

My test setup is as follow:

I've two virtual machine with Ubuntu installed. On the first virtual machine I've Tcpreplay installed to replay 
network traffic stored in one day of DARPA testing dataset to network. On the other machine, I've set IP address 
manually to one of Victim's IP address in the dataset (eg. 172.16.112.50). Also, I've installed snort-2.9.3.1 to 
protect just this machine. (HOME_NET= 172.16.112.50 & External_NET= !$HOME_NET)

I'm confused by the output alerts. After than four hours of running, snort generates about 17000 alerts that less 
than 1% of them has source or destination IP address same as my configured HOME_NET (172.16.112.50).

My second problem is detection rate. It doesn't generate any true positive alert.

Any help would be appreciated.

Regards,
Zahra Hakimi
