During use on LANs and the Internet, a computer is exposed to viruses, other malware, and a variety of attacks that exploit vulnerabilities in operating systems and software.
The firewall protects personal data that is stored on the user's computer, blocking most possible threats to the operating system while the computer is connected to the Internet or a local area network. Firewall detects all network connections of the user's computer and provides a list of IP addresses, with an indication of the status of the default network connection.
The Firewall component filters all network activity according to network rules. Configuring network rules lets you specify the desired level of computer protection, from blocking Internet access for all applications to allowing unlimited access.

Network packet rules |
Table with a list of network packet rules. 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. The table lists pre-configured network packet rules that are recommended by Kaspersky for optimum protection of the network traffic of computers that run on Microsoft Windows operating systems. Network packet rules have higher priority than network rules for applications. Firewall sets the execution priority of each network packet rule. The priority of a network packet rule is determined by its position in the list of network rules. The first network packet rule in the list has the highest priority. Firewall processes network packet rules in the order in which they appear in the list of network packet rules, from top to bottom. Firewall locates the topmost rule that applies to the network connection and executes it by either allowing or blocking network activity. Firewall ignores all subsequent network packet rules. |
Networks |
This table contains information about network connections that Firewall detects on the computer. The Public network status is assigned to the Internet by default. You cannot change the status of the Internet. |
Network rules |
Table of application network rules. In accordance with application network rules, Kaspersky Endpoint Security components regulate the file and network activity of applications in the operating system. The Firewall component regulates the access of applications to network resources. |
