 Ping is an utility to check the network connection based on TCP/IP. It sends ICMP-requests to a specified node and listens for the answer. The time between request and reply allows to understand the delay time on the route and the average package lost, therefore to determine the  stability and quality of the connection, and also to indirectly determine channel load and on the devices on the way. Ping is an utility to check the network connection based on TCP/IP.

 The “Network interfaces” utility allow to check status of every network interface on ICS CUBE. It shows the output of the “ifconfig” command, allowing to check which IP-addresses are set for each of the interfaces, which virtual interfaces has been created and also to check the link on the interfaces. The “Network interfaces” utility allow to check status of every network interface on ICS CUBE.

 You can use network scanning to test the security in the local network. It allows to check the availability of local workstations,​ and check the open ports in the network. Also, if you set ICS CUBE itself as a host to analyze, you can also check the system for open ports as well. You can use network scanning to test the security in the local network.
