KSN Proxy settings

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:

• The user's computer can query KSN and submit information to KSN even without direct access to the Internet.
• The KSN Proxy service caches processed data, thereby reducing the load on the external network communication channel and speeding up receipt of the information that is requested by the user's computer.

By default, after KSN is enabled and the KSN Statement is accepted, the application uses a proxy server to connect to Kaspersky Security Network. The proxy server used by the application is the Kaspersky Security Center Administration Server via TCP port 13111. Therefore, if KSN Proxy is not available, you need to verify the following:

• The ksnproxy service is running on the Administration Server.
• The Firewall on the computer is not blocking port 13111.

You can configure the use of KSN Proxy as follows: enable or disable KSN Proxy, and configure the port for the connection. To do so, you need to open the Administration Server properties. For details on KSN Proxy configuration, please refer to the Kaspersky Security Center Help. You can also enable or disable KSN Proxy for individual computers in the Kaspersky Endpoint Security policy.

2. In the context menu of the Installation packages folder, select Properties.
3. On the General tab in the opened window, specify the new address of the KSN proxy server.
