HTTPS with a Signed Certificate - Administrator Guide - 6.8 - Cortex XSOAR - Cortex - Security Operations

By default the server uses a self-signed certificate for a secure HTTP connection. TLS versions 1.2 and 1.3 are supported.

If you want to use your own server certificate (X.509 certificates), it is recommended to replace `/usr/local/demisto/cert.key` with the private key and `/usr/local/demisto/cert.pem` with the certificate. To create your own certificate and key, see Create a Private Key and Certificate Signing Request (CSR).

For the certificate PEM file, you must concatenate the certificate chain one after the other in the file. The SSL certificate should come first.

If you are using an intermediate certificate, the order is:

If you are not using an intermediate certificate, the order is:

Only the certificate itself is needed, i.e., the text between and including "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----".

You can store the key and certificate in a different location, by changing the /etc/demisto.conf file and adding the locations below:

{  
  "Security":{  
    "CertFile":"",
    "KeyFile":""
  }
}

Ensure both files have the correct ownership: demisto:demisto

If your private key is encrypted, you need to add the key password to the one-time-configuration (OTC) file located in /var/lib/demisto/otc.conf.json. After the file is saved and the Cortex XSOAR server is restarted, the OTC file is automatically deleted. Add the following content to the OTC file: {"keypass":"certpassword"}

In a live backup setup environment, you need to stop both servers and update the certificates on both servers before bringing them back up.
