Uploading an independently prepared TLS certificate for the Central Node server using the web interface of Kaspersky Anti Targeted Attack Platform.

You can choose to prepare the TLS certificate on your own and upload it using the Kaspersky Anti Targeted Attack Platform web interface.

The TLS certificate file prepared for upload must satisfy the following requirements:

• The file must contain the certificate itself and a private encryption key for the connection.
• The file must be in PEM format.

  The application does not support other formats of certificates.

  If you have prepared a certificate in a different format, you must convert it to the PEM format.

• The private key length must be 2048 bits or longer.

For more details on preparing TLS certificates for import, please refer to the documentation on Open SSL.

If you are already using a Central Node server TLS certificate, uploading a new certificate causes the currently used certificate to be removed and replaced with the uploaded certificate.

You must enter the data of the new certificate everywhere the old certificate was used.

If you replace the TLS certificate, you will need to:

• Reauthorize mail sensors (KSMG, KLMS) on Central Node.
• Reconfigure the connection of Central Node, PCN, and SCN to Sandbox.
• Reconfigure traffic forwarding from Endpoint Agent to Sensor and trusted connection with Endpoint Agent.
• Upload a new certificate to Active Directory (if you are using Active Directory).

Delete all Endpoint Agent host isolation rules. The connection with isolated hosts is severed and you cannot manage them.

To upload an independently prepared TLS certificate using the Kaspersky Anti Targeted Attack Platform web interface:

1. Sign in to the Kaspersky Anti Targeted Attack Platform web interface with the administrator credentials.
2. In the window of the program web interface, select the Settings section, Certificates subsection.
3. In the Server certificate section, click Upload.

   This opens the file selection window.

4. Select a TLS certificate file to download and click the Open button.

   This closes the file selection window.

• The TLS certificate is added to Anti Targeted Attack Platform. Reconfigure traffic forwarding from Endpoint Agent to Sensor and trusted connection with Endpoint Agent.
• Upload a new certificate to Active Directory (if you are using Active Directory).

Please delete all Endpoint Agent host isolation rules. Connection with the isolated hosts and control over them will be lost.
