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.
