PING Ping is used to test the reachability of a host on an Internet Protocol (IP) network. Ping works by sending an Internet Control Message Protocol (ICMP) Echo Request to a specified interface on the network and waiting for a reply. When a ping command is issued, a ping signal is sent to a specified address and it responds by sending an echo reply packet. 6. Port Scan An application can send traffic and listen on a particular port. The combination of an IP address and a port enables routing devices and the endpoint to ensure that traffic reaches the intended application. A port scan can provide a wealth of information about a target system. In addition to identifying if a system is online and which ports are open, port scanners can also identify the applications listening to particular ports and the operating system of the host. 7.
