Description

Notify of vulnerabilities in Wi-Fi networks

If this check box is selected, Kaspersky application shows notifications when any vulnerabilities are detected on a Wi-Fi network.

This check box can be accessed if Kaspersky VPN Secure Connection is not installed on the computer.

If the Block and warn about insecure transmission of passwords over the Internet check box is selected, Kaspersky application blocks the transmission of a password in non-encrypted text format when you fill in the Password field on the Internet.

Clicking the Select categories link opens the Categories window in which you can specify the types of vulnerabilities of Wi-Fi networks. The application will alert you when you try to connect to a Wi-Fi network that has a specified vulnerability.

Show devices that are connected to my networks

If the check box is selected, Smart Home Monitor is enabled and functional.

Allow connections on random ports for active FTP mode

If the check box is selected, Firewall allows connections to your computer on random ports if switching to active FTP mode was detected on the host connection.

Do not disable Firewall until the operating system shuts down completely

If this check box is selected, Firewall does not stop working until the operating system shuts down completely.

Block network connections if the user cannot be prompted for action

If this check box is selected, Firewall does not stop when the interface of Kaspersky application is not loaded.

Application rules

Clicking this link opens the Application network rules window. This window displays information related to control of the network activity of applications and application groups.

The Intrusion Prevention component regulates the network activity of applications in accordance with network rules of applications and application groups.

You can configure permissions for network activity of an application or application group via the menu of a cell in the Network column. The menu items are described in the Intrusion Prevention rules section.

By selecting Details and rules in the context menu of a row, you can proceed to configure network rules for an application or application group.

Packet rules

Clicking this link opens the Packet rules window. By default, the window shows predefined network packet rules that are recommended by Kaspersky experts for optimum protection of the network traffic of computers running Microsoft Windows operating systems.

Network packet rules serve to 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.

Network packet rules have higher priority than network rules for applications.
