About this task

A server certificate is required to support HTTPS connections. QRadar supports certificates with the following file extensions: .crt, .cert, or .der. Certificates can be manually copied to the /opt/qradar/conf/trusted_certificates directory on QRadar by using SCP or SFTP. However, you can also download the Qualys certificate from a customer URL.

  2. Download the certificate by typing the following command:
    /opt/qradar/bin/ <customer_URL>
