Which tool is best for scanning services on TCP port 443, commonly associated with HTTPS?

The most appropriate tool for scanning services on TCP port 443, which is typically associated with HTTPS, is Nmap. Nmap is a powerful network scanning tool that specializes in discovering hosts and services on a network. It can perform various types of scans, including service detection, which allows it to identify what services are running on specific ports such as 443.

Nmap's capabilities include TCP connect scans, SYN scans, and versions scanning, allowing for a comprehensive analysis of services and security postures. It can reveal not just what service is active on port 443, but also additional details such as the software version and operating system, which are crucial for security assessments.

While Nikto is indeed a web application scanner that focuses primarily on identifying vulnerabilities in web servers, it is not designed primarily for scanning network services like Nmap. Wireshark, on the other hand, is a packet capture and network analysis tool that does not scan ports but rather intercepts and analyzes data packets transmitted over the network. Burp Suite is a web application security testing tool focused on various web application attacks and testing methodologies rather than general service scanning.

Therefore, Nmap stands out as the tool best suited for scanning for services on TCP port 443, due to its
