About network packet rules

Network packet rules are actions taken by the Kaspersky Embedded Systems Security to allow or deny a detected network connection attempt.

Network packet rules impose restrictions on network packets regardless of the application. Such rules restrict inbound and outbound network traffic through specific ports of the selected data protocol.

All outbound connections are allowed by default (default action setting), unless the corresponding blocking rules for the Firewall Management are specified. The default action is performed with the lowest priority: if no other network packet rule has been triggered or if no network packet rules have been specified, the connection is allowed.

Firewall Management specifies certain network packet rules by default. You can create your own network packet rules and specify an execution priority for each network packet rule.
