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.

The infrastructure of Kaspersky reputation databases

Kaspersky Endpoint Security supports the following infrastructure solutions for working with Kaspersky reputation databases:

• Kaspersky Security Network (KSN) is the solution that is used by most Kaspersky applications. KSN participants receive information from Kaspersky and send Kaspersky information about objects detected on the user's computer to be analyzed additionally by Kaspersky analysts and to be included in the reputation and statistical databases.
• Kaspersky Private Security Network (KPSN) is a solution that enables users of computers hosting Kaspersky Endpoint Security or other Kaspersky applications to obtain access to Kaspersky reputation databases, and to other statistical data without sending data to Kaspersky from their own computers. KPSN is designed for corporate customers who are unable to participate in Kaspersky Security Network for any of the following reasons:
  • Local workstations 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.

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

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

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 Administration Server as a KSN proxy server (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 Kaspersky Security Network servers if the KSN proxy server is unavailable (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 and on the side of third parties (when Kaspersky Private Security Network is used).
