title: "Ensure APIServer is not configured with Old tlsSecurityProfile"
description: |-
The configuration <tt>tlsSecurityProfile</tt> 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:
{{% raw %}}<pre>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"}]'</pre>{{% endraw %}}
For more information, follow
OpenShift documentation:
{{{ weblink(link="https://docs.openshift.com/container-platform/latest/security/tls-security-profiles.html",
text="the relevant documentation") }}}.
rationale: |-
The authenticity and integrity of the container platform and communication
between nodes and components must be secure. If an insecure protocol,
cipher, or algorithms is used, during transmission of data, the data can be
intercepted and manipulated. To thwart the manipulation of the data during
transmission secure protocol, cipher and algorithms must be used.

ocil_clause: 'insecure tlsSecurityProfile is configured for accessing external services'
ocil: |-
To check for the configured tlsSecurityProfile use below command:
<tt>$ oc get apiservers.config.openshift.io cluster -o jsonpath='{.spec.tlsSecurityProfile.type}{"\n"}'</tt>
The output shows the tlsSecurityProfile configured for API Server, and
TLS security profile configured should not be "old".
