The configuration tlsSecurityProfile specifies TLS configurations
to be used while establishing connections with the externally exposed
servers. Though secure transport mode is used for establishing connections,
the protocols used may not always be strong enough to avoid interception and
manipulation of the data in transport. TLS Security profile configured should
not make use of any protocols, ciphers, and algorithms with known security
vulnerabilities.
tlsSecurityProfile can be configured to use one of custom, intermediate,
modern, or old profile. Profile Old should be avoided at all times and when using
custom profile one should be extremely careful as invalid configurations can be
catastrophic. It is always advised to use highly secure intermediate or modern
profiles and if unset a default is chosen.
Update tlsSecurityProfile to Intermediate using the following command:
oc patch apiservers.config.openshift.io cluster --type 'json' --patch '[{"op": "add", "path": "/spec/tlsSecurityProfile/intermediate", "value": {}}, {"op": "replace", "path": "/spec/tlsSecurityProfile/type", "value": "Intermediate"}'
