To enhance the protection of virtual machines, Kaspersky Security can use data received from Kaspersky users all over the world. Kaspersky Security Network is designed for getting such data.

Kaspersky Security Network (KSN) is an infrastructure of cloud services providing access to Kaspersky online knowledge base with information about the reputation of files, web resources, and software. Using data from Kaspersky Security Network ensures faster response of Kaspersky Security to unknown threats, improves performance of some protection components, and reduces risk of false positives.

If you are participating in Kaspersky Security Network, KSN services provide Kaspersky Security with information about the category and reputation of scanned files, as well as information about the reputation of scanned web addresses.

The types of KSN are distinguished by the location of their infrastructure:

  • Global KSN – this infrastructure is hosted by Kaspersky servers.
  • Private KSN – the infrastructure is located within the corporate network or hosted by third-party servers of the service provider, for example on the Internet service provider's network.

Information about which type of KSN is used by Kaspersky Security can be viewed in the Protection Server policy properties, in the local interface of Light Agent for Windows, and in the command line of Light Agent for Linux.

Interaction between SVMs and protected virtual machines managed by Kaspersky Security Center and the KSN infrastructure is provided by the KSN Proxy service. To use KSN in Kaspersky Security operations, the KSN Proxy service must be enabled in Kaspersky Security Center.

To use the Private KSN, it must be enabled and configured in Kaspersky Security Center.

You can select the type of KSN used by Kaspersky Security and configure the KSN proxy server service and Private KSN in Kaspersky Security Center Administration Server properties (in the KSN proxy server section in the Administration Console; in the KSN proxy server settings section in the Web Console). See Kaspersky Security Center help for more information.

You can configure the use of KSN by Kaspersky Security in the properties of the Protection Server policy.

The Light Agent uses KSN in its operation in accordance with the settings received from the SVM to which it is connected. If the Light Agent disconnects from the SVM, it continues to use the settings received the last time it was connected.

If the KSN Proxy service is disabled in Kaspersky Security Center, data exchange between Kaspersky Security components and KSN is not performed. If KSN usage is enabled in the Protection Server policy, the application performance may decrease. It is recommended to disable KSN usage in the Protection Server policy if the KSN Proxy service is disabled in Kaspersky Security Center.

Kaspersky Security components send information to Kaspersky depending on the selected KSN mode (standard KSN or extended KSN). The KSN mode affects the amount of data that is transmitted to Kaspersky when KSN is being used.

Your participation in Kaspersky Security Network when using extended KSN helps Kaspersky promptly receive information about the types and sources of new threats and develop solutions for neutralizing them.

Participation in Kaspersky Security Network is voluntary. The decision to participate in KSN is made during the creation of a Protection Server policy, and this decision can be changed at any time.
