Hint - TLS encryption

For security reasons, we strongly recommend configuring the TLS encryption.

Configuring the TLS Encryption

The SEAL Elastic Stack installation includes a self-signed TLS certificate. Replace this certificate by your own certificate to secure the connection to Kibana.

1. Get your own TLS certificate:

   • cert.pem

   • key.pem

2. Copy your TLS certificate to the following directory:

   C:\ProgramData\SEAL Systems\config\tls-external
   

   Hint - changing the TLS directory

   We recommend you use a directory different from tls for your customer certificates, e. g. tls-external.

   This allows you to easily switch back to the included certificates for test purposes.

   Also it prevents your certificates from being overwritten during an update.

   Make sure you use the new directory in all SEAL products that use TLS encryption.

3. In an editor, open the kibana.yml configuration file:

   C:\ProgramData\SEAL Systems\config\kibana.yml
   

4. Copy the following lines:

   # server.ssl.certificate: C:\ProgramData\SEAL Systems\config\tls\cert.pem
   # server.ssl.key: C:\ProgramData\SEAL Systems\config\tls\key.pem
   

5. Change the directory to the one containing your certificate:

   # server.ssl.certificate: C:\ProgramData\SEAL Systems\config\tls\cert.pem
   server.ssl.certificate: C:\ProgramData\SEAL Systems\config\tls-external\cert.pem
   # server.ssl.key: C:\ProgramData\SEAL Systems\config\tls\key.pem
   server.ssl.key: C:\ProgramData\SEAL Systems\config\tls-external\key.pem
   

6. Activate the following lines:

   server.ssl.enabled: true
   server.ssl.certificate: C:\ProgramData\SEAL Systems\config\tls-external\cert.pem
   server.ssl.key: C:\ProgramData\SEAL Systems\config\tls-external\key.pem
   

7. Save the file and exit.

8. Restart Kibana:

   start-service seal-kibana
