Kaspersky Security Network

To protect your computer more effectively, Kaspersky Endpoint Security uses data that is received from users around the globe. Kaspersky Security Network is designed for obtaining this data.

Kaspersky Security Network (KSN) is an infrastructure of cloud services providing access to the online Kaspersky Knowledge Base that contains information about the reputation of files, web resources, and software. The use of data from Kaspersky Security Network ensures faster responses by Kaspersky Endpoint Security to new threats, improves the performance of some protection components, and reduces the likelihood of false positives. If you are participating in Kaspersky Security Network, KSN services provide Kaspersky Endpoint Security with information about the category and reputation of scanned files, as well as information about the reputation of scanned web addresses.

Use of Kaspersky Security Network is voluntary. The application prompts you to use KSN during initial configuration of the application. Users can begin or discontinue participation in KSN at any time.

For more detailed information about sending Kaspersky statistical information that is generated during participation in KSN, and about the storage and destruction of such information, please refer to the Kaspersky Security Network Statement and the Kaspersky website. The ksn_<language ID>.txt file with the text of the Kaspersky Security Network Statement is included in the application distribution kit.

To reduce the load on KSN servers, Kaspersky experts may release application updates that temporarily disable or partly restrict requests to Kaspersky Security Network. In this case, the status of the connection to KSN in the local interface of the application is Enabled with restrictions.

KSN Infrastructure

Kaspersky Endpoint Security supports the following KSN infrastructural solutions:

By default, Kaspersky Security Center uses Global KSN. You can configure the use of Private KSN in the Administration Console (MMC), in the Kaspersky Security Center 12 Web Console, and in the command line. It is not possible to configure the use of Private KSN in the Kaspersky Security Center Cloud Console.

For more details about Private KSN, please refer to the documentation on Kaspersky Private Security Network.

KSN Proxy

User computers managed by Kaspersky Security Center Administration Server can interact with KSN via the KSN Proxy service.

The KSN Proxy service provides the following capabilities:

For more details on the KSN Proxy service, please refer to the Kaspersky Security Center Help Guide.

Kaspersky Security Network settings

Parameter

Description

Enable extended KSN mode

Extended KSN mode is a mode in which Kaspersky Endpoint Security sends additional data to Kaspersky. Kaspersky Endpoint Security uses KSN to detect threats regardless of the toggle position.

Enable Cloud mode

Cloud mode refers to the application operating mode in which Kaspersky Endpoint Security uses a light version of anti-virus databases. Kaspersky Security Network supports the operation of the application when light anti-virus databases are being used. The light version of anti-virus databases lets you use approximately half of the computer RAM that would otherwise be used with the usual databases. If you do not participate in Kaspersky Security Network or if cloud mode is disabled, Kaspersky Endpoint Security downloads the full version of anti-virus databases from Kaspersky servers.

If the toggle button is switched on, Kaspersky Endpoint Security uses the light version of anti-virus databases, which reduces the load on operating system resources.

Kaspersky Endpoint Security downloads the light version of anti-virus databases during the next update after the check box was selected.

If the toggle button is switched off, Kaspersky Endpoint Security uses the full version of anti-virus databases.

Kaspersky Endpoint Security downloads the full version of anti-virus databases during the next update after the check box was cleared.

Computer status when KSN servers are unavailable

(available only in the Kaspersky Security Center Console)

The items in this drop-down list determine the status of a computer in Kaspersky Security Center when KSN servers are unavailable.

Use KSN Proxy

(available only in the Kaspersky Security Center Console)

If the check box is selected, Kaspersky Endpoint Security uses the KSN Proxy service. You can configure the KSN Proxy service settings in the Administration Server properties.

Use KSN servers when KSN Proxy is not available

(available only in the Kaspersky Security Center Console)

If the check box is selected, Kaspersky Endpoint Security uses KSN servers when the KSN Proxy service is unavailable. KSN servers may be located both on the side of Kaspersky (when Global KSN is used) and on the side of third parties (when Private KSN is used).
