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 Old should be
avoided, as it supports vulnerable protocols, ciphers, and algorithms which
could lead to security breaches.
Update tlsSecurityProfile from Old 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"}, {"op": "remove", "path": "/spec/tlsSecurityProfile/old"}]'
