About Kaspersky Private Security Network

You can use Kaspersky Private Security Network (hereinafter also referred to as KPSN) instead of Kaspersky Security Network to not send data of your organization outside of the corporate LAN.

Kaspersky Private Security Network (KPSN) is a solution that lets you receive access to Kaspersky Security Network data via a server located within your organization's network. KPSN enables Kaspersky applications to receive access to the online Kaspersky Knowledge Base for information about the reputation of files, web resources, and software. KPSN does not transmit statistics and files to Kaspersky. For more detailed information, please refer to the  Kaspersky Private Security Network Administrator's Guide.

The Kaspersky Private Security Network service was designed for corporate customers who are unable to participate in Kaspersky Security Network for any of the following reasons:

• Servers have no Internet connection
• Legislative ban on transmitting any data outside of the country
• Corporate security requirements imposed on the transmission of any data outside of the corporate LAN

Application services that use KPSN in their operation do not require an Internet connection. Other Kaspersky Security components, such as the Enforced Anti-Spam Updates Service, components that perform application database updates, and components that perform application activation, require an Internet connection.

Data that the application exchanges with KPSN servers is transmitted only within the corporate LAN. The data that the application transmits to KPSN does not include statistics. The application transmits statistics only to KSN servers.

The Anti-Spam Module transmits the following data to KPSN servers:

• IP address of the sender of an email message.
• IP address of intermediate servers involved in transmitting the message and mail servers through which the message was transmitted.
• Names of the domains of the message sender from the SMTP session and MIME header.
• Web addresses contained in the scanned message. If such addresses contained passwords, the passwords are not transmitted to KPSN servers.
• Short text signatures for message text. Text signatures are irreversible compressions of text that do not allow for the original text to be restored. The message text is not transmitted. The application uses short text signatures to filter known spam campaigns and to pass verdicts based on the filtering.
• Checksum (MD5) from the email address of the sender of the message being scanned.
• Checksums (MD5) of graphic objects included in the message.
• Categories of the content filtering database.
• Text topic category determined by the application
• List of categories determined by the application during scanning by the heuristic analyzer
• Checksum (MD5) of the name of the file attached to the message

The Anti-Phishing Module transmits to KPSN servers web addresses that the application detected in a message when scanning the message for phishing links.

The Anti-Virus Module transmits the following data to KPSN servers:

• Check sums of processed files (MD5, SHA2-256)
• ID and version of the record related to the threat in the anti-virus database
