Security News > 2020 > August > Facebook Open Sources Analysis Tool for Python Code
Facebook has announced the availability of Pysa, an open-source tool designed for the static analysis of Python code.
The security-focused tool relies on Pyre, Facebook's type checker for Python, and allows for the analysis of how data flows through code.
In addition to making Pysa available in open source, Facebook released many of the definitions that it leverages when looking for security bugs, making it readily available for others to start analyzing their own Python code.
The tool also leverages open source Python server frameworks, including Django and Tornado, and this makes it usable for code analysis right from the start.
"Pysa helps security engineers both detect existing issues in a code base and prevent new ones from being introduced via proposed code changes. In the first half of 2020, Pysa detected 44 percent of the issues that our engineers found in the Instagram server codebase," the social platform reveals.
