Which tool acts as an open-source web server scanner that checks for vulnerabilities and software issues?

1. Burp Suite

2. Nikto

3. OWASP Zap

4. SQLMap

The correct answer is: Nikto

Nikto is an open-source web server scanner specifically designed to identify vulnerabilities and software issues in web servers. It performs comprehensive tests against web servers for multiple vulnerabilities, including outdated software versions, security misconfigurations, and default files and scripts. The importance of Nikto lies in its ability to automate the process of scanning a web server for common exploits, which can help security professionals detect weaknesses before they can be exploited by malicious actors. Its extensive database contains known vulnerabilities, enabling it to effectively highlight potential areas of concern on the server being assessed. While other tools like Burp Suite, OWASP Zap, and SQLMap play significant roles in web application security testing, their purposes differ. Burp Suite is primarily a web application security testing framework that allows for manual testing and automated to some extent. OWASP Zap is also a dynamic application security testing tool focused on identifying security vulnerabilities via a broader range of testing features. SQLMap is specifically designed for detecting and exploiting SQL injection vulnerabilities within web applications. Each of these tools serves a unique function in the security ecosystem, but Nikto stands out for its focused role as a web server vulnerability scanner.
