To enhance the protection of virtual machines, Kaspersky Security can use data received from Kaspersky Lab users all over the world. Kaspersky Security Network is designed to collect such data.
Kaspersky Security Network (KSN) is an infrastructure of cloud services providing access to Kaspersky Lab's online knowledge base with information about the reputation of files, web resources, and software. Data from Kaspersky Security Network ensures faster response by Kaspersky Security to unknown threats, improves the performance of some protection components, and reduces the risk of false positive.
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:
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.
You can select the type of KSN used by Kaspersky Security and configure the use of Private KSN in the properties of the Kaspersky Security Center Administration Server in the KSN proxy server section. See Kaspersky Security Center documentation for more information.
You can configure the use of Global KSN in the properties of the Protection Server policy.
The interaction between SVMs managed by Kaspersky Security Center and the KSN infrastructure is provided by the KSN Proxy service. KSN Proxy is configured in the properties of Kaspersky Security Center Administration Server.
If the KSN Proxy service is disabled in Kaspersky Security Center, no data is exchanged between SVMs and Kaspersky Security Network. If use of KSN is nonetheless enabled in the Kaspersky Security policy, this could reduce the performance of Kaspersky Security. It is recommended to disable the use of KSN in the Kaspersky Security policy if the KSN Proxy service is disabled in Kaspersky Security Center.
For details on the KSN Proxy service, please refer to the Kaspersky Security Center documentation.
Kaspersky Security sends Kaspersky Lab information depending on the KSN mode you selected (standard KSN or extended KSN). The KSN mode affects the amount of data that is transmitted to Kaspersky Lab when KSN is being used.
Your participation in Kaspersky Security Network when using extended KSN helps Kaspersky Lab promptly gather 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 Kaspersky Security Network is made during the creation of a Protection Server policy, and this decision can be changed at any time.
