Changing CA certificate

After KUMA Core is installed, a unique self-signed CA certificate with the matching key is generated. This CA certificate is used to sign all other certificates for internal communication between KUMA components and REST API requests. The CA certificate is stored on the KUMA Core server in the /opt/kaspersky/kuma/core/certificates/ folder.

You can use your company's certificate and key instead of self-signed KUMA CA certificate and key.

Before changing KUMA certificate, make sure to make a backup copy of the previous certificate and key with the names backup_external.cert and backup_external.key.

To change KUMA certificate:

1. Rename your company's certificate and key files to external.cert and external.key.

   Keys must be in PEM format.

2. Place external.cert and external.key to the /opt/kaspersky/kuma/core/certificates/ folder.
3. Restart the kuma-core service by running the sudo systemctl restart kuma-core command.
4. Restart the browser hosting the KUMA web interface.

You company's certificate and key are now used for internal communication between KUMA components and REST API requests.
