Machine learning based Web Application firewall for detection attacks such as SQL injections, XSS and shell script injections.

Course project for Mtech Student Contributors: Vikash Kumar and Ramya P L

Requirements:

• Python 3.x
• Jupyter notebook
• Python libraries
  • Pandas
  • Numpy
  • Sklearn
  • matplotlib
  • seaborn
  • scipy
• Node.js (to run demo server)

Follow along our development process in these notebooks:

• 0_Data_wrangling.ipynb (Formating other sources of payload datasets into a common format (don't step through this))
• 1_Data_cleaning.ipynb (Cleaning the data and output into a common .csv file)
• 2_Data_analysis.ipynb (All analysis, training, evaluation and saving models to pickles (not recommended to step through the training section, takes a long time))

To run notebooks (they can also be read from github):

1. Install jupyter notebook
2. type in cmd: jupyter notebook <notebookfile.ipynb>
3. step through each part of the notebook using Ctrl+Enter or from the toolbar

Plots_technical_background.ipynb contains junk used to create images for the report

Demo-server contains a Node.js server with our best classifier (in the form of a .pickle) implemented available for live testing
See README.md in demo-server for instructions on how to set up the server

images contains images used for the report

data folder contains our malicious and non-malicious data. Also contains trained classifiers in form of .pickle files
tfidf_2grams_randomforest.p contains our single best classifier
trained_classifiers.p contains all our classifiers along with performance metrics. But this is not the final version, it was too big for github. Download the final version from here: https://1drv.ms/f/s!Aj1zBHCOJiQFgbQwDswBYtpzB1Pulg and replace the old one
