WebSome of the most commonly used ports, along with their associated networking protocol, are: Ports 20 and 21: File Transfer Protocol (FTP). FTP is for transferring files between a client and a server. Port 22: Secure Shell (SSH). SSH is one of many tunneling protocols that create secure network connections. WebA port number is a unique identifier that is used in conjunction with an IP address. A port is a 16-bit unsigned integer, and there are 65,535 ports accessible under the TCP/IP architecture. As a result, the port number range is 0 to 65535. The zero-port number is reserved in TCP and cannot be utilised, but the zero port is not accessible in UDP.

By using this heuristic we detect the majority of all scans since most port scanning tools set the time between the packets to be much less than 120 seconds. sumo healthy
