Open Source Web Security Tools
Web security focuses on protecting websites, web applications, APIs, and their supporting infrastructure from unauthorized access, data exposure, and disruption. It addresses risks such as injection flaws, cross-site scripting, weak authentication, insecure configuration, and vulnerable dependencies. Good security practices help teams identify issues early, reduce the impact of attacks, and safeguard users and services throughout development and operation.
Open source tools in this area include vulnerability scanners, testing proxies, reconnaissance utilities, secure configuration aids, and educational resources. When choosing a tool, consider its maintenance activity, license, documentation, supported technologies, and fit with your existing development or testing workflow. Check whether it is intended for authorized testing and whether its requirements match your environment. These resources can help developers, system administrators, security professionals, and learners assess and improve web application defenses.
