To correctly connect to KPSN, you must use the ports that are listed for the ksn_proxy service in the Ports used by services of a Central Node deployed as a server section. When KPSN integration is configured with other ports, the connection attempt fails.
To enable the use of KPSN:
Log in to the application web interface with the administrator account.
Select the Settings section, KSN/KPSN and MDR subsection.
On the right of the Reputation database setting, click the KPSN button.
In the KPSN configuration files section, upload the kc_private.xms, kh_private.xms, and ksncli_private.dat files by clicking Browse.
Click Apply.
Use of Kaspersky Private Security Network will be enabled.
