The Network Threat Protection component (also called Intrusion Detection System) monitors inbound network traffic for activity characteristic of network attacks. When Kaspersky Endpoint Security detects an attempted network attack on the user's computer, it blocks the network connection with the attacking computer. Descriptions of currently known types of network attacks and ways to counteract them are provided in Kaspersky Endpoint Security databases. The list of network attacks that the Network Threat Protection component detects is updated during database and application module updates.
