Re: Snort against DARPA 1999 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?

Regards,
Hakimi

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:

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
