Kaspersky Endpoint Security 11 for Linux

Network Threat Protection

July 3, 2024

ID 16393

While the Network Threat Protection component is running, the application scans inbound network traffic for activity that is typical for network attacks. Network Threat Protection is started by default when the application starts.

This feature is not supported in the KESL container.

The application receives the numbers of the TCP ports from the current application databases and scans incoming traffic for these ports. Upon detecting an attempt of a network attack that targets your device, the application blocks network activity from the attacking device and logs an event about the detected network activity.

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.
