Chapter 7. Disabling TLS 1.0 and TLS 1.1 Encryption

You might want to change the encryption settings for Satellite depending on the security requirements of your infrastructure or to fix vulnerabilities quickly.

Apache and Qpid services in Satellite have TLS 1.0 and 1.1 encryption enabled by default. Use this procedure on Satellite and Capsule to configure Satellite and Capsule to only allow TLS 1.2, as required, for example, by PCI-DSS regulations.


  1. Open the /etc/foreman-installer/custom-hiera.yaml file for editing:

    # vi /etc/foreman-installer/custom-hiera.yaml
  2. Add the following entries:

    # Apache
    apache::mod::ssl::ssl_protocol: [ 'ALL' , '-SSLv3' , '-TLSv1' , '-TLSv1.1' , '+TLSv1.2' ]
    # QPID Dispatch
    foreman_proxy_content::qpid_router_ssl_ciphers: 'ALL:!aNULL:+HIGH:-SSLv3:!IDEA-CBC-SHA'
  3. Enter the satellite-installer command to apply the above configuration and configure Qpid to use TLS 1.2 only:

    # satellite-installer \
