Bandit is an effective security linter that analyzes Python code for common security vulnerabilities. By processing files and utilizing plugins against the Abstract Syntax Tree (AST), Bandit generates clear reports to enhance code security. Originally part of the OpenStack Security Project, it continues to help developers secure their codebases.
Overview
Bandit is an advanced security linter specifically designed to detect common vulnerabilities in Python code. It works by processing each file, constructing an Abstract Syntax Tree (AST), and executing relevant plugins against the AST nodes. After scanning all the files, Bandit generates a comprehensive report detailing any potential security issues.
Originally developed as part of the OpenStack Security Project, Bandit has since been transferred to the PyCQA organization, ensuring its maintenance and growth within the broader Python community.
