DVWA is a vulnerable web application sandbox and PHP security training environment. It serves as a deployable penetration testing target and an OWASP Top 10 lab designed for practicing exploits and simulating common web security vulnerabilities.
The application allows users to adjust security difficulty levels to match their skill level and toggle between different SQL database engines to test how various systems handle injection attacks. It includes a mechanism to disable authentication, enabling automated security tools to interact directly with the environment.
The project provides capabilities for vulnerability simulation, SQL injection testing, and general web security training. It includes tools for database initialization and configuration via environment variables.
