OWASP ZAP, which stands for Zed Attack Proxy, is an open-source security testing tool designed for finding vulnerabilities in web applications. It is one of the many projects maintained by the Open Web Application Security Project (OWASP), a non-profit organisation focused on improving the security of software.

Key features of OWASP ZAP include:

  1. Automated Scanning: ZAP can perform automated scans of web applications to identify common vulnerabilities such as cross-site scripting (XSS), SQL injection, security misconfigurations, and more.
  2. Man-in-the-Middle (MITM) Proxy: ZAP operates as a proxy between the user's browser and the target web application, allowing users to intercept and inspect requests and responses. This makes it an effective tool for manual testing and analysis.
  3. Spidering and Fuzzing: ZAP includes features for spidering, which helps map the structure of a web application, and fuzzing, which involves sending malformed or unexpected data to uncover potential vulnerabilities.
  4. Authentication Support: ZAP supports various authentication methods, allowing testers to assess how well an application handles authentication and authorisation.
  5. Scripting and Automation: Users can create and run scripts using ZAP's own scripting language or with other scripting languages like JavaScript. This enables automation of repetitive tasks and the creation of custom test scenarios.
  6. API Testing: ZAP can be used to test APIs (Application Programming Interfaces) for security vulnerabilities. It supports REST and SOAP API testing.
  7. Dynamic SSL Certificates: ZAP can generate and use dynamic SSL certificates, making it suitable for testing applications that use HTTPS.
  8. Reporting: ZAP provides detailed reports on the vulnerabilities identified during scanning. These reports help developers and security professionals understand and address security issues.
  9. Active and Passive Scanning: ZAP supports both active scanning, where it actively probes the application for vulnerabilities, and passive scanning, where it monitors traffic and identifies potential security issues.
  10. Community and Updates: Being an open-source project, ZAP benefits from a community of contributors. Regular updates and improvements are made to keep the tool current and effective against evolving threats.

OWASP ZAP is commonly used by security professionals, penetration testers, and developers to identify and remediate security issues in web applications. It's important to note that ZAP should be used responsibly and ethically, with proper authorisation to test web applications. Unethical or unauthorised use of security testing tools can have legal consequences.
