The figure below shows the hierarchy of Administration Servers: the primary Administration Server is on a local area network (LAN). A secondary Administration Server is in the demilitarized zone (DMZ); another secondary Administration Server is on the internet.

The arrows indicate the initiation of traffic: each arrow points from a device that initiates the connection to the device that "answers" the call. The number of the port and the name of the protocol used for data transfer are provided. Each arrow has a number label, and details about the corresponding data traffic are as follows:
Network Agents send requests to each other within one broadcasting domain. The data is then sent to the Administration Server and is used for defining the limits of the broadcasting domain and for automatic assignment of distribution points (if this option is enabled).
If Administration Server does not have direct access to the managed devices, communication requests from Administration Server to these devices are not sent directly.
If you used an earlier version of Kaspersky Security Center, the Administration Server on your network can receive connection from Network Agents through non-SSL port 14000. Kaspersky Security Center also supports connection of Network Agents through port 14000, although using SSL port 13000 is recommended.
The distribution point was called "Update agent" in earlier versions of Kaspersky Security Center.
If you do not want your Administration Server to have access to the internet, you must manage this data manually.
9a. Data from the browser, which is installed on a separate device of the administrator, is transferred to Kaspersky Security Center 13 Web Console Server through TLS port 8080. The Kaspersky Security Center 13 Web Console Server can be installed either on the Administration Server or on another device.
