The application stores data of DLP Module, such as data of policies, incidents and categories, as well as statistics of DLP Module, in the DLP database.
The DLP database is operated with Microsoft SQL Server. By default, the DLP database is deployed along with the database of Backup and statistics. You can export tables from the DLP database to another database under a different name or deploy the DLP database on a different SQL server. You can also configure the application to switch to using another instance of the DLP database that has been created in advance in case of a failure in the DLP database's operation (for example, due to an error on the SQL server). To do this, you need to configure the connection to the DLP database.
When installing the DLP Module in an organization, you must make sure that the backup data and statistics database that was specified during the DLP Module installation on the first Microsoft Exchange server is available on all other Microsoft Exchange servers. Otherwise, errors may occur during the application installation, which may lead to the DLP Module inoperability.
Under a high intensity of the mail flow in your organization and a large number of policies that determine the number of incidents to be created, the DLP database may have a significant volume. This should be taken into account when planning the deployment of the DLP database. You can use the incident archiving feature to reduce the DLP database size (see To Administrator section for more details).
Kaspersky Security does not provide channel encryption during data transmission between the server and the SQL database. To secure your data, manually encrypt data to be transmitted over communication channels.
