SSL connections between QRadar components

To establish all internal SSL connections between components, QRadar uses the web server certificate that is preinstalled on the QRadar Console.
All trusted certificates for QRadar must meet the following requirements:
  • The certificate must be an X.509 certificate and have PEM base64 encoding.
  • The certificate must have a .cert, .crt, .pem, or .der file extension.
  • Keystore files that contain certificates must have the .truststore file extension.
  • The certificate file must be stored in the /opt/qradar/conf/trusted_certificates directory.
