Administration Server and client device: Managing the security application

The Administration Server receives connection from Network Agents via SSL port 13000 (see figure below).

A client device connects to Administration Server through SSL port 13000. Administration Server connects to the client device through UDP port 15000.

Administration Server and client device: managing the security application, connection via port 13000 (recommended)

If you used an earlier version of Kaspersky Security Center, the Administration Server on your network can receive connections from Network Agents via non-SSL port 14000 (see figure below). Kaspersky Security Center 14.2 also supports connection of Network Agents via port 14000, although using SSL port 13000 is recommended.

A client device connects to Administration Server through TLS port TCP 14000. Administration Server connects to the client device through UDP port 15000.
