Bandit
Security linter from PyCQA that processes Python ASTs to find common vulnerability patterns and insecure library usages.
Technical Architecture & Overview
Bandit is an open-source static analysis tool designed to find common security issues in Python code. It analyzes the AST of Python files and flags issues like assert statements, hardcoded passwords, insecure shell execution, and weak cryptographic operations.
Targeted Technical Use Cases
Automated Python security linting in pre-commit hooks and CI/CD pipelines.
Evaluation & Trade-offs
Core Strengths
- +Maintained by PyCQA after starting within the OpenStack Security Project.
- +Builds an AST for each file and runs check plugins against its nodes.
- +Extensible with custom plugins and configurable severity levels.
Trade-Offs & Limitations
- -Focused on Python only; no cross-language support.
- -Detects known anti-patterns rather than complex data-flow vulnerabilities.
Defensive Security Application
Catching common Python security anti-patterns before code is committed or merged.
