While the Network Threat Protection component is running, the application scans inbound network traffic for activity that is typical for network attacks. Kaspersky Industrial CyberSecurity for Linux Nodes receives the numbers of the TCP ports from the current application databases and scans incoming traffic for these ports.
To scan network traffic, the Network Threat Protection task receives port numbers from the application databases and accepts connections via all these ports. During the network scan process, it may look like an open port on the device, even if no application on the system is listening to this port. It is recommended to close unused ports by means of a firewall.
Upon detection of a network attack attempt aimed at your computer, the application logs the corresponding event, and can also block network activity from the attacking computer.
