- What is this?: The HTTP dataset CSIC 2010 contains thousands of web requests automatically generated. It can be used for the testing of web attack protection systems.
It was developed at the “Information Security Institute” of CSIC (Spanish Research National Council).
- Motivation: A current problem in web attack detection is the lack of
publicly available data sets to test WAFs (Web Application Firewalls). The DARPA data
set [1, 2] has been widely used for intrusion detection.
However, it has been criticized by the IDS community .
Regarding web traffic, some of the problems of the DARPA
data set are that it is out of date and also that it does not
include many of the actual attacks. Because of that, it is
not appropriate for web attack detection. The problem of
data privacy is also a concern in the generation of publicly
available data sets and is probably one of the reasons why
most of the available HTTP data sets do not target real web
Because of these reasons, we decided to generate our
own HTTP data set CSIC 2010 and we present it here.
- Dataset Description:
The HTTP dataset CSIC 2010 contains the generated traffic targeted to an e-
Commerce web application developed at our department. In this web application,
users can buy items using a shopping cart and register by providing some personal information. As it is
a web application in Spanish, the data set contains some
The dataset is generated automatically and contains 36,000
normal requests and more than 25,000 anomalous requests. The
HTTP requests are labeled as normal or anomalous and the dataset includes attacks such as SQL injection, buffer overflow, information gathering, files disclosure, CRLF injection,
XSS, server side include, parameter tampering and so on.
This dataset has been successfully used for web detection in previous
works [4, 5, 6, 7, 8, 9].
The traffic is generated following the next steps:
data are collected for all the parameters of the web application.
All the data (names, surnames, addresses,
etc.) are extracted from real databases.
These values are stored in two databases: one for the normal
values and other for the anomalous ones.
Additionally, all the
public available pages of the web application are listed.
Next, normal and anomalous requests are generated for every web
page. In the case that normal requests have parameters, the
parameter values are filled out with data taken from the normal
database randomly. The process is analogous for anomalous requests, where the values of the parameters are taken from the anomalous database.
Three types of anomalous requests were considered:
1) Static attacks try to request hidden (or non-existent)
resources. These requests include obsolete files, session
ID in URL rewrite, configuration files, default files, etc.
2) Dynamic attacks modify valid request arguments: SQL
injection, CRLF injection, cross-site scripting, buffer
3) Unintentional illegal requests. These requests
do not have malicious
intention, however they do not follow the normal behavior of the web application
and do not have the same structure as normal parameter values (for example, a telephone number composed of letters).
The attacks were generated with the help of tools such as Paros
 and W3AF.
The WAFs where this dataset was used [4,5,6,7] follow the anomaly approach, i.e. the normal behavior of the web application is defined and the behavior apart from that are considered anomalous. Therefore, in this approach only normal traffic is needed for the training phase.
The dataset is divided into three different subsets. One subset for the training phase, which has only normal traffic. And two subsets for the test phase, one with normal traffic and the other one with malicious traffic.
