Ensure 'zosSecurity-1.0' feature is 'enabled' for SAF authorization

中レベル 1自動websphere

説明

The SAF role mapper should be used to perform SAF authorization checks when accessing applications. This recommendation only applies to Liberty on z/OS; on other platforms the audit reports not applicable and passes. 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. Requires the zosSecurity-1.0 feature and a <safAuthorization> element.

Configure the zosSecurity-1.0 feature and set the safAuthorization element in ${server.config.dir}/configDropins/overrides/<any file name>.xml. <feature>zosSecurity-1.0</feature> <safAuthorization id="saf" />
