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.
Procedure
Open the
/etc/foreman-installer/custom-hiera.yamlfile for editing:# vi /etc/foreman-installer/custom-hiera.yaml
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'
Enter the
satellite-installercommand to apply the above configuration and configure Qpid to use TLS 1.2 only:# satellite-installer \ --foreman-proxy-content-qpid-router-ssl-protocols=TLSv1.2
