Which tool is typically used to scan services running on TCP port 443?

The correct answer is Nikto, which is a web server scanner primarily designed to identify vulnerabilities within web servers, particularly those that utilize the HTTP protocol, including secure connections on TCP port 443 (HTTPS). Nikto works by performing various checks to detect insecure files, outdated software versions, and potential misconfigurations on the server. As TCP port 443 is commonly used for secure web traffic, Nikto's capabilities make it an ideal tool for assessing the security posture of services running on this port.

Using Nikto to scan services on port 443 allows security professionals to gather information about the web application's security vulnerabilities and identify areas that may require further mitigation or protection. Its ability to automate the process of vulnerability detection saves time and provides thorough insights into web server security.

While tools like Metasploit and sqlmap serve specific purposes—Metasploit for exploiting vulnerabilities and sqlmap for testing and exploiting SQL injection vulnerabilities—they are not primarily designed for the general scanning of web service vulnerabilities on port 443 like Nikto is. ZZUF is a tool used for fuzzing, which is not directly related to scanning services on specific ports.
