OWASP Python Security Project
Python Security is a free, open source, OWASP project that aims at creating a hardened version of python that makes it easier for security professionals and developers to write applications more resilient to attacks and manipulations.

The project is designed to explore how web applications can be developed in python by approaching the problem from three different angles:

Introduction
Python Security is a free, open source, OWASP project that aims at creating a hardened version of python that makes it easier for security professionals and developers to write applications more resilient to attacks and manipulations.

The project is designed to explore how web applications can be developed in python by approaching the problem from three different angles:

Security in python: white-box analysis, structural and functional analysis Security of python: black-box analysis, identify and address security-related issues Security with python: develop security hardened python suitable for high-risk and high-security environments

Detection
AppSensor defines over 50 different detection points which can be used to identify a malicious attacker.

Response
AppSensor provides guidance on how to respond once a malicious attacker has been identified. Possible actions include: logging out the user, locking the account or notifying an administrator. More than a dozen response actions are described.

Defending the Application
An attacker often requires numerous probes and attack attempts in order to locate an exploitable vulnerability within the application. By using AppSensor it is possible to identify and eliminate the threat of an attacker before they are able to successfully identify an exploitable flaw.

Licensing
OWASP AppSensor is free to use.

What is AppSensor?
Detect and respond to attacks from within the application. This project includes both a well documented idea (the Guide) and a reference implementation (the Code).

Volunteers
All OWASP projects rely on the voluntary efforts of people in the software development and information security sectors. They have contributed their time and energy to make suggestions, provide feedback, write, review and edit documentation, give encouragement, make introductions, produce demonstration code, promote the concept, and provide OWASP support. They participated via the project’s mailing lists, by developing code, by updating the wiki, by undertaking research studies, and through contributions during the AppSensor working session at the OWASP Summit 2011 in Portugal and the AppSensor Summit at AppSec USA 2011. Without all their efforts, the project would not have progressed to this point, and this guide would not have been completed.

OWASP Summer of Code 2008
The AppSensor Project was initially supported by the OWASP Summer of Code 2008, leading to the publication of the book AppSensor v1.1.

Google Summer of Code 2012
Additional development work on SOAP web services was kindly supported by the Google Summer of Code 2012.

Other Acknowledgements
The project has also benefitted greatly from the generous contribution of time and effort by many volunteers in the OWASP community including those listed above, and contributors to the OWASP ESAPI project, members of the former OWASP Global Projects Committee, the OWASP Board, OWASP staff and support from the OWASP Project Reboot initiative. The v2 code and documentation were conceived during the AppSensor Summit held during AppSec USA 2011 in Minneapolis.

= Road Map and Getting Involved =

Please join the project's mailing lists to keep up-to-date with what's going on, and to contribute your ideas, feedback, and experience:
 * General project
 * Code development

Non code

 * Update AppSensor Guide to keep in step with code changes and improvements to ideas (see discussion and editable list of changes)
 * Create demo
 * Develop training materials

v2 Code
The current code being worked on is located on GitHub

The code has been fully rewritten. v2.0.0 final was released in late January 2015. v2.1.0 final was released in June 2015.

The main reason for the rewrite was to allow a client-server style model as opposed to requiring AppSensor be fully embedded in the application. You can now have a central server collecting events from multiple applications and performing analysis. These front-end applications can be in any language as long as they speak rest/soap. There's been a host of other changes, but this was the primary one. A number of starter ideas for coding, user interface and documentation have been outlined via the mailing list at 17th March 2014.

if you want to work on ANYTHING, please let jtmelton[@]gmail.com know.
