Synchronization of policies, application settings, tasks, and task settings

Updating the information on applications and tasks running on client com-
puters
•
Delivery of events to be processed on the server
In most cases, client computers are connected to the server. This connection is
used to automatically exchange data between the clients and the server and to
send information about application events to the server.
Automatic synchronization is performed at regular time intervals defined by the
Network Agent settings (for example, once every fifteen minutes). The time
interval is set by the administrator.
Information about an event is sent to the server immediately after the event
occurs.
In the client settings, you can check/uncheck the
Keep connection
checkbox to
keep or terminate the client–server connection after the above operations are
over. Permanent connection is preferred if connecting to a client is impaired for
some reasons (the client is behind a firewall, client ports cannot be opened, the
client IP address is unknown, etc.) or you need to constantly monitor the
performance of Kaspersky Lab applications.
The administrator can force synchronization to start by clicking the
Force
synchronization
command on the shortcut menu of the client computer
(see section 2.10.4 on page 31). In this case, the connection is initiated by the
server. To enable connection, the UDP port is opened on the client computer.
The server sends a connection query to the client’s UDP port. In response, the
server rights to connect to the client are verified (based on a digital signature),
and, if the signature is valid, the connection is established.
A second type of connection is also used to retrieve data from client computers –
update the lists of applications and tasks running on the client and refresh
application statistics.
2.3. Secure connection to the
Administration Server
Data exchange between clients and the Administration Server and connections
of the console to the Administration Server are secured by SSL protocol (Secure
Socket Layer). SSL protocol is responsible for authentication of communicating
parities, encryption of the data being transferred and preventing modification of
data during the transfer. Data integrity ensures that the data has not been
corrupted or altered in transit. An SSL-enabled connection involves
