About KSN

Kaspersky Security Network (KSN) is an online service infrastructure that provides access to the online Knowledge Base of Kaspersky, which contains information about the reputation of files, web resources, and software. The use of data from Kaspersky Security Network ensures faster responses by Kaspersky applications to threats, improves the effectiveness of some protection components, and reduces the risk of false positives. KSN allows you to use Kaspersky reputation databases to retrieve information about applications installed on managed devices.

Kaspersky Security Center supports the following KSN infrastructure solutions:

• Global KSN is a solution that allows you to exchange information with Kaspersky Security Network. If you participate in KSN, you agree to send to Kaspersky, in automatic mode, information about the operation of Kaspersky applications installed on client devices that are managed through Kaspersky Security Center. Information is transferred in accordance with the current KSN access settings. Kaspersky analysts additionally analyze received information and include it in the reputation and statistical databases of Kaspersky Security Network. Kaspersky Security Center uses this solution by default.
• Private KSN is a solution that allows users of devices with Kaspersky applications installed to obtain access to reputation databases of Kaspersky Security Network, and other statistical data, without sending data to KSN from their own computers. Kaspersky Private Security Network (Private KSN) is designed for corporate customers who are unable to participate in Kaspersky Security Network for any of the following reasons:
  • User devices are not connected to the internet.
  • Transmission of any data outside the country or outside the corporate LAN is prohibited by law or restricted by corporate security policies.

  You can set up access settings of Kaspersky Private Security Network in the KSN Proxy settings section of the Administration Server properties window.

The application prompts you to join KSN while running the Quick Start Wizard. You can start or stop using KSN at any moment when using the application.

You use KSN in accordance with the KSN Statement that you read and accept when you enable KSN. If the KSN Statement is updated, it is displayed to you when you update or upgrade Administration Server. You can accept the updated KSN Statement or decline it. If you decline it, you keep using KSN in accordance with the previous version of KSN Statement that you accepted before.

Client devices managed by the Administration Server interact with KSN through KSN proxy server. KSN proxy server provides the following features:

• Client devices can send requests to KSN and transfer information to KSN even if they do not have direct access to the internet.
• The KSN proxy server caches processed data, thus reducing the load on the outbound channel and the time period spent for waiting for information requested by a client device.

You can configure the KSN proxy server in the KSN Proxy section of the Administration Server properties window.
