Ensure 'httpsRequired' is set to 'true' in OIDC Relying Party (RP)
Descripción
HTTPS protocol protects the integrity and confidentiality of data between the client and the server. Audit: reads server.xml, configDropins/defaults/*.xml, configDropins/overrides/*.xml and files pulled in with <include> for every Liberty server found under WLP_USER_DIR, /opt/ibm/wlp/usr, /opt/IBM/WebSphere/Liberty/usr, /opt/ol/wlp/usr, /usr/local/wlp/usr or /config; it ignores XML comments and fails if no server.xml is readable. httpsRequired on <openidConnectClient> must not be false. Passes when no <openidConnectClient> element is configured (feature not in use). An unset attribute is accepted because the Liberty default is compliant.

Cómo se corrige
Método de corrección: Guía o parche de infraestructura
Add the httpsRequired attribute to the openidConnectClient element to ${server.config.dir}/configDropins/overrides/*.xml and set it to true to ensure that security transport is used for JSON Web Tokens. <openidConnectClient httpsRequired="true" />
