Expose & Explore: Discover misconfigured service protocols and ports using Linux
1 min read
Summary
Ports are unique numerical identifiers assigned to every application or service that enable communication between these and other services over a network.
Port numbers range from 0 to 65,535, with the well-known ports ranging from 0 to 1,023, registered ports from 1,024 to 49,151, and dynamic or private ports from 49,152 to 65,535.
The Linux operating system enables users to analyse ports and discover potential vulnerabilities, and this article will look at doing that.
One of the most effective tools for this purpose is Nmap, a free and open-source utility that analyses ports and is widely used for cybersecurity purposes.
Nmap enables users to see which ports are open and recognise potential vulnerabilities, making it an essential part of system administration.
